Intel UHD Graphics (Elkhart Lake 32 EU) vs Intel UHD Graphics G4 (Lakefield GT1 48 EU)
Intel UHD Graphics (Elkhart Lake 32 EU)
► remove from comparison
The Intel UHD Graphics 32EUs Elkhart Lake (Gen. 11) is an integrated graphics card (iGPU) in the Elkhart Lake Pentium and Celeron SoCs (e.g., Pentium J6226). It was announced in early 2021 and is used in the high end Elkhart Lake CPUs. It uses all 32 execution units and offers no dedicated graphics memory. The clock speed depends on the CPU model and ranges from 4000 MHz (minimal base clock speed) up to 850 MHz (highest Boost clock).
The gaming performance is very low and only very low demanding 3D games should be playable. The slower 16 EU variant was even struggling in our Dota 2 benchmark.
Intel UHD Graphics G4 (Lakefield GT1 48 EU)
► remove from comparison
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.
| Intel Gen.11 Graphics Cards | Cores | Base | Boost |
|---|---|---|---|
| Intel Iris Plus Graphics G7 Ice-Lake | 64 EUs | 300 MHz | 1100 MHz |
| Intel Iris Plus Graphics G4 Ice-Lake | 48 EUs | 300 MHz | 1050 MHz |
| Intel UHD Graphics G1 Ice-Lake | 32 EUs | 300 MHz | 1050 MHz |
| Intel UHD Graphics G7 Lakefield | 64 EUs | 200 MHz | 500 MHz |
| Intel UHD Graphics G4 Lakefield | 48 EUs | 200 MHz | 500 MHz |
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.
