Intel UHD Graphics Xe 16EUs (Tiger Lake-H) vs Intel Iris Xe Graphics G7 96EUs vs Intel Iris Xe Graphics G7 80EUs

The Intel UHD Graphics Xe 750 (Rocket-Lake GPU with 16 EUs) is a integrated graphics card in the low end Tiger Lake-H CPUs. It is using the new Xe architecture (Gen12) and was announced in May 2021. This variant only uses 16 of the 32 EUs in the chip (=128 shaders) and therefore is significantly slower than the 32 EU version.

Compared to the previous generation of UHD Graphics ,the Xe architecture and the improved shader count lead to a big leap in graphics performance.

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 Xe Graphics G7 80EUs (Tiger-Lake U GPU with 80 EUs) is a integrated graphics card in the mid range Tiger-Lake U CPUs (15 - 28 Watt, e.g. Core i5 11th Gen CPUs). It is using the new Xe architecture (Gen12) and should be announced later in 2020.

The performance depends on the TDP settings of the laptop and the used cooling. First informations show that the chip can be configured at 15 and 28 Watt TDP default (as the Ice Lake-U chips) and the performance should be around a dedicated GeForce MX330 in 3DMark benchmarks. For gaming we are expecting a bit worse performance due to the missing dedicated graphics memory and driver support. Compared to the older Iris Plus G4 in Ice Lake chips, the Tiger Lake GPU should be nearly twice as fast. Benchmarks with various laptops show that the 80EU version lacks about 18% behind the faster 96EU version and on par with the MX330. Compared to AMD iGPUs, the G7 80EU positions itself around the Vega 7 and Vega 8 chips (see chart below for details).

Therefore, the iGPU is still only for lowest graphical settings and low resolutions in demanding games. Some modern games like Days Gone or Cyberpunk wont run over 30 fps in minimum settings (see below).

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.
