Intel UHD Graphics 32EUs (Alder Lake) vs Intel Iris Xe Graphics G7 96EUs vs Intel UHD Graphics Xe 750 32EUs (Rocket Lake)

The Intel Xe Graphics G7 (Tiger-Lake U GPU with 96 EUs) is a integrated graphics card in the high end Tiger-Lake U CPUs (15 - 28 Watt). It is using the new Xe architecture (Gen12) and was introduced in September 2020. The GPU clocks with a base clock speed (guaranteed) of 400 MHz in all CPUs and can boost up to 1340 MHz (i7-1185G7). The slowest variant offers only 1100 MHz boost (i5-1130G7, 12 Watt TDP).

The performance depends on the TDP settings of the laptop and the used cooling. First informations show that the chip can be configured at 12 and 28 Watt TDP default (as the Ice Lake-U chips) and the performance should be around a dedicated GeForce MX350 in 3DMark benchmarks. For gaming we are expecting a bit worse performance due to the missing dedicated graphics memory and driver support. Many games e.g. had problems when testing the various laptops (e.g. Horizon Zero Dawn or Cyberpunk 2077 did not start or were crashing - see list below). Less demanding games like the Mass Effect Legendary Edition ran in medium settings fine. Compared to the older Ice Lake Iris Plus G7 GPU, the new Tiger Lake GPU should be approximately twice as fast. Therefore, the iGPU is still only for lowest graphical settings and low resolutions in demanding games.

The Tiger Lake SoCs and therefore the integrated GPU are manufactured in the modern 10nm+ (10nm SuperFin) process (improved 10nm process) at Intel and therefore should offer a very good efficiency.

The Intel UHD Graphics Xe 750 (Rocket-Lake GPU with 32 EUs) is a integrated graphics card in the high end Rocket-Lake CPUs. It is using the new Xe architecture (Gen12) and was announced in March 2021.

Compared to the previous generation of UHD Graphics ,the Xe architecture and the improved shader count lead to a big leap in graphics performance. Still, the UHD 750 is only suited for low demanding games or very low settings. The 48 EU version in Tiger Lake SoCs e.g. reached 46 fps in The Witcher 3 low 1024x768 and no fluent framerates in Mafia Definitive Edition.

The Rocket Lake SoCs and therefore the integrated GPU are manufactured in the old 14nm+++ process at Intel.
