Intel HD Graphics 630 vs Intel UHD Graphics 770

Intel HD Graphics 630

The Intel HD Graphics 630 (GT2) is an integrated graphics card, which can be found in various desktop and notebook processors of the Kaby-Lake generation (Kaby-Lake-H quad-core chip). The "GT2" version of the GPU offers 24 Execution Units (EUs) and the clocks depend on the CPU model. Due to its lack of dedicated graphics memory or eDRAM cache, the HD 630 has to access the main memory (2x 64-bit DDR3L-1600 / DDR4-2133).

Performance

The exact performance of the HD Graphics 630 depends on various factors like TDP, L3 Cache, memory (DDR3/DDR4) and maximum clock rate of the specific model. However, it should be fairly similar to the HD Graphics 530 (see for gaming benchmarks) and therefore only suited for low demanding games like Overwatch or Farming Simulator 2017 (low details).

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. HDMI 2.0 however is still only supported with an external converter chip (LSPCon).

Power Consumption

The HD Graphics 630 can be found in several notebook and desktop processors of different TDP classes (35 - 91 W). Thanks to the improved 14nm+ process, the power consumption could be slightly lower compared to Skylake CPUs.

Intel UHD Graphics 770

The UHD Graphics 770 is an integrated graphics card (IGP, GT1) in Alder Lake and Raptor Lake SoCs that offers 32 execution units (EUs) and a clock speed of up to 1.65 GHz (depending on the CPU model).

The performance depends on the CPU model it is integrated in and the used memory. The gaming performance is even on fast models only suited for low demanding games in 720p and low detail settings. Higher demanding games like Cyberpunk 2077 or Dying Light 2 (see benchmarks below) did not run well in our tests.

The GPU supports up to 4 displays with eDP 1.4b (5k120), DisplayPort 1.4a (8k60) and HDMI 2.1 (4k60). 

The Alder Lake SoCs are manufactured in the "Intel 7" named process (enhanced 10nm at Intel).
