Intel UHD Graphics P630 vs Intel UHD Graphics G4 (Lakefield GT1 48 EU) vs Intel Iris Plus Graphics 645
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 Iris Plus Graphics 645
► remove from comparisonThe Intel Iris Plus Graphics 645 (GT3e) is a processor graphics card that was first seen in the Apple MacBook Pro 13 (Entry, 2019) in mid 2019. It is similar to the Iris Plus Graphics 655 in the 28 Watt CPUs.
The so called GT3e version of the Coffee-Lake GPU still has 48 Execution Units (EUs), which can reach up to 1150 MHz depending on the model. Besides eDRAM cache, the Iris 645 can also access the system memory (2x 64 Bit DDR3L-2133/DDR4-2400) via processor interface.
Performance
The exact performance of the Iris Plus Graphics 645 depends on the CPU model, because maximum clock as well as the size of the L3 cache can differ a bit. The system memory (DDR3/DDR4) will influence the performance as well.
The fastest chips are high-clocked Core i7 models like the Core i7-8557U. Depending on the game, the Iris Plus 655 will probably be on par with a dedicated GeForce 930M or GeForce 940MX and can handle smooth gameplay in modern titles in low up to medium settings.
Features
The reworked video engine now fully supports hardware decoding of H.265/HEVC videos. Contrary to Skylake, however, Kaby Lake can now also decode H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The video output is possible via DP 1.2/eDP 1.3 (up to 3840 x 2160 @60 Hz), whereas HDMI is also supported in the older 1.4a standard. An HDMI 2.0 output can be added via converter from DisplayPort. The GPU can drive up to three displays simultaneously.
Power Consumption
The Iris Plus Graphics 645 is used for 15-Watt processor and therefore small-sized notebooks.
