Intel UHD Graphics G4 (Lakefield GT1 48 EU)

Intel UHD Graphics G4 (Lakefield GT1 48 EU)

The Intel UHD Graphics G4 (Lakefield GT1 with 48 EUs) is an integrated graphics card in the Lakefield SoCs (e.g. Core i3-L13G4) 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 should be a bit slower than the old Intel HD Graphics 620 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.
