Intel UHD Graphics (Jasper Lake 16 EU) vs Intel UHD Graphics G7 (Lakefield GT2 64 EU) vs Intel UHD Graphics (Elkhart Lake 16 EU)

The Intel UHD Graphics 16 EUs (Jasper Lake, Gen. 11) is an integrated graphics card in the Jasper Lake Celeron SoCs for laptops and small desktops. It is the low end GPU version in the Jasper Lake series (Celeron Dual-Cores) and offers only 16 of the 32 EUs (Execution Units / Shader Blocks). It offers no dedicated graphics memory and the clock rate depends on the processor model. At launch there are two Celeron models (N4500 with 6W and N4505 with 10W) clocked at 350 - 750 MHz.

Thanks to the improved architecture and more EUs, the UHD Graphics is clearly faster than the old Gemini Lake SoCs (e.g. UHD Graphics 600).

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).

Another improved hardware piece is the integrated video de- and encoder that was improved significantly according to Intel. They did not specify any more details, but the previous generation was able to decode VP9 and H.265/HEVC in Main10 profile with 10 bit color depth using the dedicated hardware.

The Jasper Lake SoCs and therefore the integrated GPU are manufactured in the 10nm process (like Ice Lake probably) at Intel that should be comparable to the 7nm process of TSMC.

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.
