Difference Between Intel Processor Generations

The last time I went to the computer shop to inquire about the latest prices of laptops, I was told the new laptop had the Intel fourth-generation processor. I asked the person the difference between first-generation and fourth generation, but he was unable to answer properly, saying the fourth generation was faster than the 1st, 2nd and 3rd generations.

So I came home and wanted to know about the philosophy of processor generations on the Internet. To my surprise, there was no complete guide available, which could tell clearly about the Intel processor generations and their differences. After researching a lot, I have enough knowledge to write and document the differences I have found in this article.

Intel Processors

The misconception

First of all, many people think that Core i3, i5, and i7 are the processor generations. These are models or brands of processors from Intel. I will write another article later, as it requires a lot of discussion. Let me list all the major processor models released by Intel.

  • Pentium 1, 2, 3, 4
  • Celeron
  • Pentium M and Celeron M for mobile devices
  • Pentium Dual Core
  • Core Solo
  • Core Duo
  • Core 2 Duo
  • Core 2 Quad
  • Core i3, i5, i7, i9

The concept of generations mainly comes after the release of the Core i series. The difference in processor micro-architecture is the main difference in processor generations. We will discuss these generations in detail below.

Intel core processor names and numbers

As you can see from the image above, the complete name of the processor can confuse you. That is why we are here to clear out any doubts about the information contained within the names of a Core processor.

The name of an Intel Core processor contains the following information:

  • Brand
  • Brand Modifier
  • Generation Indicator
  • SKU
  • Product Line Suffix

Brand

The Brand signifies the overall product line. It could be any one of the following:

  • Core
  • Xeon
  • Pentium
  • Celeron

Brand Modifier

A Brand Modifier is only used in the Core series to signify the processor’s performance. You can find the following modifiers currently available (at the time of writing this post):

  • i3
  • i5
  • i7
  • i9

The higher the modifier, the greater its performance.

Generation Indicator

In the 4 or 5-digit processor number, you will find the generation of the processor in the 1st or the 1st and 2nd digits.

If the processor is from a generation with only one integer (for example 8th or 9th), then the numbers would be starting like 8XXX or 9XXX. However, if it is of the 10th or 11th generation, the numbers would be line 10XXX or 11XXX.

The generation signifies some of the processor’s attributes, such as when it was released, the size of the transistors used, cache type and size, etc.

SKU

The SKU signifies the model number, which is usually the last 3 digits in the product number. The higher the SKU, the more features the processor is likely to have.

That said, SKUs cannot be used to compare processors amongst different Intel brands or different generations.

Product Line Suffix

The suffix at the end also signifies the capabilities of a processor. This is an alphabet that highlights the key features of the processor. Below is a list of all the suffixes currently in use by Intel and their meaning:

  • C: Desktop processor with high-end graphics
  • F: High-performance processor used with discrete graphics cards (ex. Gaming)
  • H: High-performance graphics
  • K: Unlocked for overclocking
  • M: Mobile
  • Q: Quad-core
  • R: Desktop processor, BGA1364 (mobile) package, high-end graphics
  • S: Performance-optimized lifestyle
  • T: Power-optimized for best desktop computing
  • U: Ultra-low power for laptop efficiency
  • X: Extreme unlocked for high desktop performance
  • Y: Extreme low power

Let us now continue to discuss the different Intel Core generations.

Intel Processor Generations

Intel processor generations simply have an enhanced feature set and speed compared to previous generations. Let’s discuss each generation separately.

1st Generation Intel Processors – Nehalem

Nehalem was the Intel processor micro-architecture which was the successor to the initial Core architecture which had certain limitations like inability to increase the clock speed, inefficient pipeline, etc. Nehalem was released for production in 2010.

Nehalem used the 45-nanometer process as opposed to the 65nm or 90nm used by previous architects. Nehalem reintroduced hyper-threading technology which was left out mainly in the initial Core i3 processor models.

The Nehalem processor has a 64 KB L1 cache, 256 KB per core L2 cache and 4 MB to 12 MB L3 cache which is shared with all the processor cores. It supports 1156 LGA socket and 2-channel DDR3 RAM.

2nd Generation Intel Processors – Sandy Bridge

Sandy Bridge micro-architecture was introduced in 2011 to replace Nehalem architecture. Sandy Bridge uses the 32-nanometer process as opposed to 45 nm used in Nehalem. Sandy Bridge processor average performance enhancement as compared to Nehalem was about 11.3%.

Sandy Bridge uses the same 64 KB L1 cache and 256 KB per core for L2 cache but the difference is in the L3 cache. Normally the Sandy Bridge processor L3 cache was from 1MB to 8 MB. For extreme processors, it was from 10 MB to 15 MB. It uses 1155 LGA socket and 2-channel DDR3-1066 RAM.

3rd Generation Intel Processors – Ivy Bridge

Introduced in September 2012, Ivy Bridge processors are faster than Sandy Bridge processors and use the 22-nanometer process as opposed to 32 nm used in Sandy Bridge. This processor model consumes up to 50% less energy and will give 25% to 68% increase in performance as compared to Sandy Bridge processors.

The only problem with Ivy Bridge processors is that they may emit more heat as compared to Sandy Bridge processors.

Ivy Bridge architecture uses the same 1155 LGA socket with DDR3-1333 to DDR3-1600 RAM.

4th Generation Intel Processors – Haswell

Haswell was released by Intel in June 2013. It uses the same 22-nm process as Ivy Bridge. The performance improvement of Haswell as compared to the Ivy Bridge is from 3% to 8%. Haswell carries a lot of features from Ivy Bridge with some very exciting new features like support for new sockets (LGA 1150, BGA 1364, LGA 2011-3), DDR4 technology, a completely new cache design, etc.

The main benefit of Haswell is that it can be used in ultra-portable devices due to its low power consumption.

5th Generation Intel Processors – Broadwell

Broadwell was released by Intel in 2015. It uses 14-nm process technology which is 37% smaller in size than its predecessors. According to Intel, with the Broadwell CPU, the device’s battery life could be improved as long as 1.5 hours.

The Broadwell chips also feature faster wake times and improved graphics performance. It supports 1150 LGA sockets with 2-channel DDR3L-1333/1600 RAM.

6th Generation Intel Processors – Skylake

Intel introduced Skylake, the 6th generation processors in August 2015. Skylake is a redesign of the same 14-nm technology which was introduced in Broadwell, the 5th generation architecture.

7th Generation Intel Processors – Kaby Lake

Intel’s 7th generation processors, codenamed Kaby Lake, were introduced in 2016. Kaby Lake is essentially a refresh of Sky Lake architecture with few efficiencies and power improvements. It uses a 14-nm process architecture.

Kaby Lake is the first micro-architecture from Intel that does not come with an official driver for Operating Systems older than Windows 10.

Kaby Lake introduced a new graphics architecture to improve 3D graphics performance and 4K video playback. It uses 1151 LGA sockets and has dual-channel support for DDR3L-1600 and DDR4-2400 RAM slots.

8th Generation Intel Processors – Kaby Lake R

In 2017, Intel introduced a refresh of Kaby Lake processors as their new 8th generation release. The details are the same as mentioned in the 7th Generation Intel Processor but some 8th generation chipsets have support for DDR4-2666 RAM but lack DDR3L RAM support.

9th Generation Intel Processors – Coffee Lake

Coffee Lake processors were introduced by Intel in late 2017. With this architecture, Intel Core i9 processors were introduced.

Coffee Lake processors break the limit of 4 cores per CPU. The new processors can now support up to 8 cores per CPU.

Since the heat produced in these cores will be enormous, Intel attached the integrated heat spreader (IHS) to the CPU die instead of the thermal paste which is normally used in earlier processors.

It uses 1151 LGA sockets with altered pinouts to support more than 4 cores along with up to 16 MB of L3 cache.

10th Generation Intel Processors – Cannon Lake/Ice Lake

Cannon Lake, Intel’s 10th generation architecture, comes with an all-new 10-nm technology. It was released in late 2017 but production properly started in 2018.

Ice Lake is produced as the 2nd generation of 10-nm processors.

They use BGA1526 sockets and come with DDR4 3200 and LPDDR4X 3733 support. This is the first CPU architecture that comes with integrated support for Wi-Fi 6 (802.11ax) and Thunderbolt 3.

11th Generation Intel Processors – Tiger Lake

The 11th generation Intel, Tiger Lake, is the third generation of 10-nm transistor technology, released on September 2, 2020. The Tiger Lake architecture has up to 19% performance gains compared to Ice Lake. L4 cache has been introduced in this generation for further performance boosts.

Furthermore, this was the first generation to feature Intel Iris Xe graphics with significant FPS boosts whilst gaming.

12th Generation Intel Processors – Alder Lake

The 12th generation of Intel Core processors is referred to as Alder Lake. It also has 10-nanometer transistor technology, but with hybrid capabilities. This means it is both designed for power and scalability with its P-cores and E-cores, which essentially means power core and efficiency cores, respectively.

This generation supports DDR5 memory, Thunderbolt 4 connectivity, and WiFi 6E (Gig+).

Intel claims the 12th generation provides an average of 13% performance gains in gaming and offers up to twice the performance of its predecessor in terms of content creation.

The next generations

The next generation of Intel Core processors is the 13th with the codename Raptor Lake. It is anticipated to be released in the second half of 2022. It is rumored to have double-digit performance boosts in comparison to Alder Lake, and may have up to 24 threads.

  1. Muy laptop is core m3 , what is core m3

  2. At least get gen 6th if you’re buying a computer. Support for NVMe begins in gen 6th. It’s a worthy improvement above gen 5th and before.

  3. Excellent. Thank you for taking of your time to explain about the generation. I spent time looking making my research for my laptop purchase but none of the sites explain it as you did. Thank you. It was very helpful for me.

  4. Bro Usman

    Make the discussion easier for the fellows like me, who is just a common layman, never mind please. I ain’t really good or at home in the pretty vast amd versatile field of computer hardware and its technology, etc. Please help me pinpointedly what should I buy for my domestic or day to day office use, or for my school going kids: a 1st Gen Core i7, or better a 3rd Gen Core i3 instead?

    Salam alykum
    Faraz (Karachi)

    1. Hi Faraz, this really depends upon your exact needs. You have to take a lot of things into account while buying a PC like processor generation and speed, cache, the support RAM frequency, hard drive/SSD support etc. Generally speaking, the newer generations are always faster than the previous ones.

  5. THIS IS BRILLIANT…..THANK YOU VERY MUCH USMAN KHURSHID!!!!!

    Im in the process of getting a new laptop. I was so focused on getting a core i5 or i7 and SSD vs HDD and other specs i completely forgot about the generation. When i was in town earlier comparing prices at different shops i asked one guy why he were much more expensive than other shops. He couldnt answer me. When I got back home i googled his shop & laptop and compared it to the other guys and realize both were exacly the same exept his were a 10th gen and the others were 6th gen… i was like no way, this is going to be days of research and its black friday time…lol

    Your article were 2nd on the list when i googled about generations. It took me 5 min instead of many days of research. Great work bro, i am grateful!!!

  6. Edward Hart says:

    You have the last few code names mixed up a little bit. Kaby Lake is the name for the 7th gen processors, but the code name for 8th gen is Coffee Lake, and 9th gen is Coffee Lake Refresh. This is from Intel’s website. 10th gen is listed as Comet Lake, although I am pretty sure I saw Ice Lake listed somewhere, and 11th gen for the IoT applications is Tiger Lake.

    Best information arounding generation
    It helps to find out processor generation how work its performance
    Thank You

  8. Nitesh Modi says:

    Thanks for the information.

    Please give the info about this(First of all, many people think that Core i3, i5, and i7 are the processor generations. These are models or brands of processors from Intel. I will write another article about these later as it requires a lot of discussions.) Is this article uploaded?
    And at last thanks for the information about generations…

  9. Cyron Rome Natividad says:

    thanks for the info…
    it helps me to know which generation is better…

    i hope you can make a research if which processor is recommended for office, for online tutors, and for gaming..

    thanks ????

  10. This article is unfortunately very low level quality, and not complete. There is also lots of mistake.
    For example, Haswell was still DDR3. Natively supported DDR3-1600 Mhz.

    First generation Nehalem, was not introduced in 2010, but in 2008. Socket 1156 was actually later one, mid-range. Primary, Nehalem was for socket 1366 high-end platform. Even Lynnfield processors (socket 1156) have been released in 2009, not in 2010. In 2010, there was die-shrink, from 45nm process to 32nm process, this architecture was called Westmere, or Nehalem-C. It’s still considered as first generation though.

    You should rewrite this article with more info, and repair false info.

  11. Wian Knoetze says:

    Good info except for one thing. The 4th gen i7 CPU’s are 4 core 8 thread CPU’s, which means they have 4 physical cores with hyper-threading. The 4th gen i5 CPU’s also have 4 physical cores but no hyper-threading. The 4th gen i3 CPU’s are 2 core 4 thread CPU’s, which means they have 2 physical cores with hyper-threading.

  12. You’re correct. This Usman guy has no idea what he’s talking about. He’s clearly never heard of an i7 4770 or i7 4700hq.

    1. Dustin thank you for the comment. I definitely have used those processor models myself. But those are high-end processor models with four cores (usually seen in workstation laptops). By default, the normal 4th generation Core i7 processor comes with only 2 cores.

      1. no. just no. even the 2nd gen i7 had 4 cores.

        1. By default, the 2nd gen had two cores. Four cores were available only for special processors made for Workstation laptops etc. But with Gen 8th, Core i7 comes with 4 cores by default.

  13. Jerry Schimpf says:

    Usman Khurshid, thank you so much for your comprehensive history of the different Intel processor generations. Your information is so valuable for me to see the evolution of the Intel generations. I’m in the process of choosing a new laptop for business & surveillance purposes and don’t know if I should wait for the newest Tiger Lake laptop (since I’m not a “gamer”). I would like the most powerful processor I can get as I need lots of ram to manage my wifi cameras in two locations. If you have time to make any suggestions, I would be extremely grateful. In the meantime, thank you again for the timeline you provided and hope you have a Happy New Year 2020, Jerry

    1. Hi Usman, It’s 2020. We’re trying to make a point with my wife’s stingy university why the 4th generation i7 processor is so much slower than today’s generation of i7 processors. For the the Haswell you write “The performance improvement of Haswell as compared to the Ivy Bridge is from 3% to 8%. ” Can you tell us in general what the improvement is for each successive generation? Thank you.

      1. The most prominent and easy difference between a 4th generation Core i7 processor and an 8th/9th/10th generation Core i7 processor is that the later comes with 4 physical cores while the 4th gen processor comes with only 2 cores. This can have double performance benefits depending upon the type of work we’re doing. This alone is convincing enough to go for the latest generation processors.

        1. This is clearly incorrect. All 4th gen i7 processors come with 4 physical cores.

          1. Jason 4th Gen Core i7 processors come with 2 cores by default and hyper-threading enabled. This means that you will see 4 logical processors in Windows 10 task manager. If you have an 8th Gen Core i7 processor, you will see 8 logical processors in the task manager.

        2. Technical Issues says:

          Incorrect, the core i7 4th gen comes with 4 cores and you can tell just by doing a simple google search. You’re mostly correct though, the newer generation comes with more cores (6 cores for 8th gen i7). This means the main difference is that the Core i7 has more performance, can run multiple programs easily, and way faster than the 4th generation.

  14. Jerrod Looney says:

    Hi, good info just a note on one of them: It says 9th gen broke the 4 core/cpu barrier, but the 7th gen 7820 has 8 cores and my 8700k has 6 cores. I believe that the 6700 uses DDR4 from then forward as well. Just thoughts on what I have personally.

    1. Good points Jerrod. By breaking the barrier I meant that the 6 and 8 core CPUs will be available as standard options. I have used some Dell laptops which were 7th gen and had 6 cores but they had and “H” processor. Likewise, your 8700K means you have the fastest of the Intel processor processors available. DDR4 was selectively available in sixth generation laptops but was not common. 7th gen laptops normally come with DDR4 RAM.

  15. What is 2nd generation dual core processor? Does it fit LGA 1155 socket?
    Then CPUs which for LGA 775 are of which generation?

    1. For LGA 775, you have no generation. It is basicaly pre-first generation.

      They were Core 2 duo and Core 2 Quad processors. It was even before first generation of Nehalem. The core 2 had basicaly 2 generations. First, when it was introduced, on 65nm process in 2006. The processors like Q6600, Q6700, QX6800. Average speed was 2,4Ghz. Then, little bit later, they made second socket 775 generation on 45nm process. The average speed was about 2,8-3 Ghz. It was mainly famous Q9650, Q9400 etc… line. But also Q8400.

      For dual-core processors, they used number like E6800 for first generation, and E8600 etc… for second.
      There were only 2 and 4 core processors.

      After it, nehalem first generation came, and they started to use i3-xxx/i5-xxx/i7-xxx names.

  16. Thank you for this information. It might seem trivial for some people but you’ve compiled it really well.

  17. DR SUHAIL YOUSAF CHUGHTAI says:

    Great informative blog .. thank you for the effort.

  18. By chance i have read this CPU related article in 2019 which is now half unrelated scinece many generations have come to existence.

      1. Yup!..:) And Waqas’ comment is “now half unrelated”, as the article has been updated. Thank you Admin! (Hehe)

  19. Javeria Fayyaz says:

    Can’t anybody pl tell processor speed difference according to different generations

  20. Mohammed Mehboob says:

    Hi,
    How about 5th,6th & 7th generations of i3 processor? What about their names?

  21. How about an updated article? It’s 2019. Thanks.

      1. Floyd Sullens says:

        Isn’t there a 9th Generation already out or on the verge?

        1. 10th Gen Intel® Core™ processors is out, btw. That’s not the issue. Problem is that Meltdown and Spectre (& ALL of the variants) are still ever-present on Intel’s CPU hardware – and there seems to be NO solution in sight; and this is YEARS later -now- after the initial discovery…

          Nobody is talking about how this is a BACKDOOR provided by the IME, Intel Management Engine: originally designed for “ease of use” (or, whatever their -evil- spin is on the matter) and, then, it has backfired; & they can’t get rid of it, as it is part of their hardware manufacturing system.

          With AMD on the rise (once again!), there will -hopefully- never be a need to, ever, purchase any Intel CPUs, ever again..:)

          P.S. For anybody interested, there are companies which HAVE BEEN aware of these issues (since while back!) & are working on solutions. For example, run a search query for: “System76 disable Intel IME”.

          1. v1adimir thanks for your detailed comment. The ninth-generation Core i series includes hardware fixes for Meltdown V3 and L1 Terminal Fault. As you said, they are not fully patched yet but Intel is working towards a permanent solution.

            When it comes to AMD processors, I don’t see a lot of variety when it comes to AMD laptops. AMD still has a long way to catch up.

    1. Joanna Nasios says:

      yes please update !

  22. What is the difference between i3 -6’th gen and 8th gen?

    1. Tapas majumder says:

      cache memory have different i3 6th generation cache memory 4mb and
      i3 8generation have cache memory 12mb

  23. Prabhu ran says:

    It’s good research guy

  24. Cool, very good work thanks friend. I thin you should update this post and add the socket used the gen

  25. thanks for the detail information on intel processors

  26. Ron Slater says:

    being a tech idiot. I cannot under stand what you have written. My question is still what difference is there to the average purchaser between 1st 2nd 3rd or 4th generation of Tablets.

    1. Abhishek Dubey says:

      Difference is same like Hero Spelender and Hero Passion, you will feel the difference when you will do hardcore computing, it depends on your work as well. if you are doing typing work only then any processor will workout but when you will use new applications, advanced software applications then you will require more calculation power which you will get only in new processors. Every time in computer world technology changes and you need something better. And you know, research work is always moving forward in computer world. So that is why you get a new generation every year. I hope it helps.

  27. Monica DiFranco says:

    It would be nice to see this article updated to include the most recent processors. The laptop I just bought this past week has a Core I-7 Generation 8 processor, so there is more information to be catalogued.

    1. I’m I am thinking to buy a new desktop PC. does your laptop works fast then please tell me what processor and how much RAM you are using

      1. my laptop has i7 processor with amd radeon gpu and 6gb ram….with these inside my laptop alhamdulillah I’m able to play games on my laptop peacefully.
        but it will be better if you have 8gb ram. so you can avoid any unwanted things from happen to your pc/laptop’s gaming perfomance
        but I’d prefer pc…it’s just because I’m a student so I can’t bring my whole desktop with me all along.

  28. Hammad Ahmed says:

    sir what is the difference b/w core i7 and core i7 quadcore processor?

  29. Vincent LaVallee says:

    This list as jut about anything I can find online does not give a list of CPUs by generation. This is a critical list because when buying CPUs you must marry the CPU with a motherboard that can support them. Motherboard support is by CPU generation for the Intel processors. Therefore, I need to know the exact CPU model number and what generation it belongs to. The best list would be by generation, giving all the CPU model numbers that are in each generation. But if you give me a list simply by CPU model number, I can always use Excel and reorder them into the generation group.

  30. I was confusing about the different between 1rst 2 3 4 generation, thanks for explaining

  31. Wow.. It helps me alot.. Thanks :)

  32. wish you could tell us how to identify the generation of a processor – it is, IMO, more useful than know the weird names given to them. Will i7-8700 be the 8th generation? because of the 8 in 8700?

  33. sadik shaik says:

    I am in small confusion, i need to buy a new laptop. but i saw two laptops, one is i5 processor 7th generation, and another one is i5 processor 8th generation.
    Can you please let me know which one is best?
    Thanks in advance.

    1. Rahul Kumar says:

      7th generation of computer is working fine from progressing time and 8th generation is new in market. You should compare the both laptops with clock speed, ram cache size, HDD RPM and with more configurations. Happy New Year.

  34. Please update. Also please create a graphic showing the performance of each generation (you could use typical frequency for each generation if the same frequency is not used across all generations). Also, another graphic showing the energy consumption for a mix of tasks. A table summarizing everything would be great. Thank you.

  35. pratik malaviya says:

    I shared my leptop detail with friends the one of them ask me ” which processer in your leptop?..and which genration? “… my answere was i-7 GEN and processer is also same… i’m confuse to answere it… if possible you can tell me this in briefly ….

    1. i7 is processor model after the model name you will have 4 digits. first one indicates which generation and the rest indicates the speed.
      eg i7 7200U
      i7-model
      7-generation
      200-speed

  36. This gaves me idea to all those generation thing.. u help me decide what to buy, coz I was about to purchase a computer set..
    Thanks man. Good Job.

  37. sherjeel ch says:

    little bit informative but not as relevant as i need

    1. Sharjeel what type of information do you need? The article seems outdated. I’m updating it right now to reflect the latest changes in processor generations.

      1. Krishna Requina says:

        Yes the article is outdated, kindly update it. It is really helpful. Thank you and God bless.

      2. I have an i7 2nd gen. Considering upgrading to maybe a 6th gen. Is it worth the upgrade or no? I dont want the expense of a new 7th or 8th gen machine.

  38. Darren Chenery says:

    If my memory serves me correctly.
    Intel’s first PC processor was the 8086 (often referred to as the AT) followed by the 80186, 80286, 80386 80486 (referred to without the 80 prefix eg 286) then came the pentiums.

    1. first was 8088 then 8086

  39. nSedrickm says:

    thanks this was helpfull please update to include up to 7th gen processor architecture

  40. k vaidyanathan says:

    thanks for your explanation. till i read this article i was thinking that there is vast difference in working of the system because of the generation change.

  41. William Bevalet says:

    Great article…Can I swap a first generation to a sixth gen without changing anything else? Thanks

    1. its not as simple as replacing the processor to upgrade. since these processors support different ram eg ddr 4 ddr3 , also the motherboard needs to be replaced since the CPU architecture is not supported on all motherboards .so yiu need to do some research first.

  42. Mukeem Khan says:

    this is awesome information for me. Please update and collect new information about next generation. thanks

  43. hey like someone said previously there are more generations out now and we would like you to continue the article and compare the 5th, 6th, and 7th generations of the intel core thanks for the well need article that listed all and only information listed.

  44. Mohd Azher shareef says:

    It’s great knowledge article.thank you very much

    Thank You Very Much That Is Much Helpful For Me.

  46. Currently there are more generations now available 5th 6th 7th and counting. I believe that 4th generation was the best one (Hasswell). Great Explanation by the way.

    In list of early processors, I don’t see the ‘Pentium Pro.’ I remember that it was highly rated at the time. I have one in my computer junk pile. Good article. Thanks for doing the research!

  55. Ahmad Nofal says:

    Man I wanna thank you very much for this nice and helpful topic

  56. A little correction about that line:
    “Nehalem used 45 nanometer process as opposed to the 65nm or 90nm used by previous architectures”

    Nehalem was actually a fourth processor series to use 45nm production process. Previous architectures using it were Core 2 Duos: Wolfdale (2 cores mostly), Penryn (mobile, 1 to 4 cores) and Yorkfield (4 cores). First of these were introduced about a year before first Nehalem. I still use some of them.

    Thank you so much,

  62. Like the article.it widen my knowledg in processor generation thanks

  63. Muhammad Akram Rana says:

    Really useful article to understand generations of the processors -thanks.

  64. Syed Imran says:

    can you please explain about graphic card

    1. 1st gen = directx10
      2nd gen = directx10.1
      3rd gen = directx11
      4th gen = directx11.1
      5th gen = directx11.2
      6th gen = directx12

  65. Good summary. Thanks for the info! I had the same trouble finding a good walk through the Intel generations.

  66. The Truth says:

    In a nutshell they are all the same shit

  67. Nice Knowledge,
    Thanks for sharing …

  68. I am confused between two processors. Shall I go with first generation i7 or forth generation i5

  69. LouisGelua says:

    broadwell then skylake

  70. So if I have a third generation Core i7 in my laptop, could I buy a new laptop with a fourth or fifth gen i5 chip and still have superior performance?

    1. checkout the processor performance charts at passmark.com. select “benchmarks” then “cpu benchmarks”. you just might find a new i5 beats an old i7. but if the performance is similar, is it really worth upgrading?

  71. NANDA KISHORE says:

    Thanks for your nice article. You mentioned that “The only problem with Ivy Bridge processors is that they may emit more heat as compared to Sandy Bridge processors.” How about Haswell processor–Does it also emits more heat? Thanks for your clarification.

    1. As far as I have read in different forums, Haswell also has problems with heating the CPU but haven’t done any experimentation on that.

    which kind of generations are they?

    1. Hi
      these are not generatoins, these are brand names(or models)

  74. Sathishkumar says:

    Thank you so much for your information.

  75. Mohammad Azharuddin Qadri says:

    Its true there is no complete guide about processors,
    I asemble a new PC (desktop) i3 (i3-3210) third generation in februry. I am confuse about AMD and Intel processor I have no time research so I go to intel. But after 6 months I discover AMD is better for small office and daily works, some time I feel its better then intel. I want your opinion or post about it.

    1. Azharuddin, I am still in process of writing about i3, i5 and i7 processors. You can a good idea that I should also write about AMD in addition to Intel. Will definitely keep this in mind.
