Gen9.5 Gen11

Gen10 (Generation 10) is the microarchitecture for Intel's graphics processing unit utilized by Cannonlake-based microprocessors. Gen10 is the successor to Gen9.5 used by Kaby Lake.

The display portion of this architecture is also used by Goldmont Plus, however, it still uses Gen9.5 for the execution units.

Due to Intel skipping over Cannon Lake, Gen10 graphics have never been productized.

Codenames

Various models support different Graphics Tiers (GT) which provides different levels of performance. Some models also support an additional eDRAM side cache.

Code Name	Description
GT1	Contains 1 slice with 24 execution units.
GT2	Contains 1 slice with 40 execution units.
GT3	Contains 2 slices with 48 execution units.
GT3e	Contains 2 slices with 48 execution units. Has an additional eDRAM side cache.
GT4e	Contains 3 slices with 72 execution units. Has an additional eDRAM side cache.

Key changes from Gen9.5

• Display
  • HDMI 2.0 (from 1.4a)
    • 2160p (4K) @ 60 Hz (from 24 Hz)
• Execution Units
  • Double EU for graphics tier 1 (GT1) (24 Execution Units, 2x EUs)
  • Higher EU count for graphics tier 2 (GT2) (40 Execution Units, 1.7x EUs)

This list is incomplete; you can help by expanding it.

Overview

Gen10 graphics were originally intended to ship with Cannon Lake-based chips, however, continuous issues and prolong delays with their 10 nm process as forced Intel to skip over this design. No Gen10-based chips have ever been productized.
