Intel UHD Graphics G7 (Lakefield GT2 64 EU) vs Intel UHD Graphics 64EUs (Alder Lake 12th Gen) vs Intel UHD Graphics 24EUs (Alder Lake-N)

The Intel UHD Graphics G7 (Lakefield GT2 with 64 EUs) is an integrated graphics card in the Lakefield SoCs (e.g. Core i7-L16G7) for laptops. It offers no dedicated graphics memory (no eDRAM cache like the Intel Iris Graphics 655 predecessor of the Coffee Lake SoCs). The clock rate ranges between 200 MHz (guaranteed base clock) up to 500 MHz (boost). The TDP of the whole SoC is specified at 7 Watt.

The GPU performance is similar to the old Intel HD Graphics 630 and therefore only some low demanding games like League of Legends should run with the UHD Graphics.

A special new feature of the Gen11 graphics card is the new Variable Rate Shading (VRS) support. With it game designers can decide where to spend shading time and e.g. shade object in the background or behind fog with less resolution (up to using only one source for a 4x4 block). With this technique early results show up to 1.3x performance in Unreal Engine POC and 1.2x speedup in Civ 6. Up to now VRS is only supported by the new Nvidia Turing architecture (GTX 1650 and up).

The Lakefield SoCs and therefore the integrated GPU are manufactured in the modern 10nm process at Intel that should be comparable to the 7nm process of TSMC.

The Intel UHD Graphics 80EUs (12th Gen Alder Lake GPU, Xe Architecture with 80 EUs) is an integrated graphics card in the mid range Alder-Lake CPUs. It is using the new Xe architecture (Gen12) and was introduced with the Alder Lake-H series. In theoretical benchmarks the GPU is on par with the Radeon RX Vega 8 (iGPU of Ryzen 4000 CPUs) but in games the performance is a bit worse due to less optimized drivers (in 2022). E.g. in our tests only low demanding games like GRID Legends were playable in low settings.

The SoC is manufactured in an improved 10nm process (called Intel 7).

The Intel UHD Graphics 24EUs (Xe-LP, Alder Lake-N, Gen 12.2) is a integrated graphics card in the mid range Alder Lake-N models like the Intel Processor N100. It is using the current Xe-LP architecture (Gen12) and was announced in late 2022. The GPU uses 24 of the 32 EUs (execution units) in the chip (192 of the 256 shader cores).

The performance is severely hindered by the single channel memory controller of Alder Lake-N, the low CPU performance and relatively low shader count. Therefore, only very low demanding games like Dota 2 in lowest settings can be played with the UHD Graphics GPU.

The whole SoC is manufactured in 10nm (Intel 7 process) at Intel.
