  4. Supported the 1155 LGA socket and 2-channel DDR3-1066 RAM.

3rd Generation Intel Processors – Ivy Bridge (2012):

  1. Ivy Bridge processors, introduced in September 2012, boasted a faster 22-nanometer process, compared to Sandy Bridge’s 32 nm.
  2. They offered up to 50% energy savings and a performance boost of 25% to 68% over Sandy Bridge processors.
  3. Notably, Ivy Bridge processors may emit more heat than their predecessors.
  4. Utilized the same 1155 LGA socket and supported DDR3-1333 to DDR3-1600 RAM.

4th Generation Intel Processors – Haswell (2013):

  1. Haswell, released in June 2013, continued to use the 22-nanometer process.
  2. Performance improvement over Ivy Bridge ranged from 3% to 8%.
  3. Haswell introduced new features, including support for new sockets (LGA 1150, BGA 1364, LGA 2011-3), DDR4 technology, and a redesigned cache.
  4. Known for its low power consumption, making it suitable for ultra-portable devices.

5th Generation Intel Processors – Broadwell (2015):

  1. Released in 2015, Broadwell introduced 14-nm process technology, offering a 37% size reduction.
  2. Promised improved battery life, up to 1.5 hours longer.
  3. Featured faster wake times and enhanced graphics performance.
  4. Supported the 1150 LGA sockets with 2-channel DDR3L-1333/1600 RAM.

6th Generation Intel Processors – Skylake (2015):

  1. Skylake, introduced in August 2015, is a redesign of the 14-nm technology used in Broadwell (5th generation).

7th Generation Intel Processors – Kaby Lake (2016):

  1. Kaby Lake, released in 2016, is essentially a refresh of the Skylake architecture with efficiency and power improvements.
  2. Introduced a 14-nm process architecture.
  3. Enhanced 3D graphics and added support for 4K video playback.
  4. Officially supported Windows 10.
  5. Used 1151 LGA sockets and supported dual-channel DDR3L-1600 and DDR4-2400 RAM slots.

8th Generation Intel Processors – Kaby Lake R (2017):

  1. Introduced in 2017 as a refresh of Kaby Lake processors.
  2. Similar to the 7th Generation Intel Processors but with some chipsets supporting DDR4-2666 RAM while lacking DDR3L RAM support.

9th Generation Intel Processors – Coffee Lake (2017):

  1. Introduced in late 2017, Coffee Lake included Intel’s first i9 processors.
  2. Supported up to 8 cores per CPU.
  3. Used 1151 LGA sockets with altered pinouts to support more than 4 cores and up to 16 MB of L3 cache.
  4. Integrated heat spreader (IHS) directly attached to the CPU die for heat management.

10th Generation Intel Processors – Cannon Lake/Ice Lake:

  1. Cannon Lake introduced new 10-nanometer technology in late 2017.
  2. Ice Lake followed as the 2nd 10-nm generation.
  3. Used BGA1526 sockets and supported DDR4 3200 and LPDDR4X 3733 RAM.
