Intel UHD Graphics P630 vs Intel UHD Graphics G4 (Lakefield GT1 48 EU) vs Intel HD Graphics P630
Intel UHD Graphics P630
► remove from comparisonThe Intel UHD Graphics P630 (GT2) is a professional integrated graphics card, which can be found in various Xeon desktop and notebook processors of the Coffee-Lake generation. 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 UHD P630 has to access the main memory (2x 64-bit DDR3L-1600 / DDR4-2133). Compared to the older HD Graphics P630 (Kaby-Lake), the newer UHD GPU is identical but can be clocked slightly higher. Compared to the regular UHD 630, the P630 supports ECC main memory and is intended for professional applications.
Performance
The exact performance of the UHD Graphics P630 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 and HD Graphics 630 and therefore only suited for low demanding games like Overwatch or Farming Simulator 2017 (low details).
Features
The features of the UHD P630 are the same as for the HD 630 and therefore H.265/HEVC Main10 profile at 10-bit color depth are supported 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 UHD Graphics P630 can be found in several notebook and desktop processors of different TDP classes.
Intel UHD Graphics G4 (Lakefield GT1 48 EU)
► remove from comparisonThe 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.
Intel HD Graphics P630
► remove from comparisonThe 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.
