The performance improvement of Haswell as compared to the Ivy Bridge is from 3 to 8.I asked the person the difference between first-generation and the fourth generation but he was unable to answer properly, saying that the fourth generation was faster than the 1st, 2nd and 3rd generations.I have updated this article to add all the latest generations released after initially writing this article.If there is anything missing in the article, please let me know and I will try to add it as soon as possible.
So I came home and wanted to know about the philosophy of processor generations on the Internet. To my astonishment, 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 that I can write and document the differences which I have found in this article. The misconception First of all, many people think that Core i3, i5, and i7 are the processor generations. I will write another article about these later as it requires a lot of discussions. Let me list down 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 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. Intel Processor Generations Intel processor generations simply have an enhanced feature set and speed compared to previous generations. Lets discuss each generation separately. 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 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. 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. ![]() 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. Generation Intel Processors Haswell Haswell was released by Intel in June 2013.
