Intel HD Graphics P630 vs Intel UHD Graphics (Elkhart Lake 32 EU)

Intel HD Graphics P630

The Intel HD Graphics P630 (GT2) is an integrated graphics unit, which can be found in various Xeon workstation processors of the Kaby Lake generation. The "GT2" version of the Skylake GPU offers 24 Execution Units (EUs) clocked at up to 1050 MHz (depending on the CPU model). Due to its lack of dedicated graphics memory or eDRAM cache, the P630 has to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133). It uses the same silicon as the consumer HD Graphics 630 in Kaby-Lake-H processors but features optimized drivers for workstaion and CAD software. According to Intel it is certified for 15 applications (see list).

Performance

According to Intel, the performance of the P630 is identical to the Intel HD Graphis P530 (Skylake predecessor) processor graphics card and 1.94x faster than the old Intel HD Graphics P4000. Compared to consumer cards, the gaming performance should be on a similar level to the dedicated GeForce 920M and will handle old games (as of 2015) in low or medium settings.

Features

The revised video engine in the Kaby Lake chips now supports H.265/HEVC Main10 profile at 10-bit color depth and also the VP9 codec in hardware. Furthermore, HDCP 2.2 is also supported in all chips, which allows Netflix 4K videos, for instance.

Power Consumption

The HD Graphics P630 can be found in mobile quad-core Xeon processors with 45 W TDP and also desktop processors of the Xeon range with higher TDPs.

Intel UHD Graphics (Elkhart Lake 32 EU)

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.
