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.
4. Integrated support for Wi-Fi 6 (802.11ax) and Thunderbolt 3.

11th Generation Intel Processors – Tiger Lake (2020):
