AMD Radeon R9 M395 vs Intel Iris Plus Graphics 650 vs Intel HD Graphics P630
AMD Radeon R9 M395
► remove from comparisonThe AMD Radeon R9 M395 is a high-end mobile graphics card that can be found in the 2015 iMac 5K 27-inch. It offers 1792 shader cores (28 compute cores) clocked at 834 MHz. The 2 GB GDDR5 dedicated graphics memory is connected with a 256 Bit bus at 1365 (= 5460 effective) MHz.
The performance should be between the older Radeon R9 M295X and the Desktop Radeon R7 370. Therefore, demanding Windows games like Fallout 4 or Call of Duty: Black Ops 3 should run in maximum details at 1920x1080 (with no headroom).
Intel Iris Plus Graphics 650
► remove from comparisonThe Intel Iris Plus Graphics 650 (GT3e) is a processor graphics card for Kaby Lake models announced in January 2017. As the successor to the Intel Iris Graphics 550 (Skylake), the Iris Plus Graphics 650 is used for 28-Watt models and is equipped with 64 MB eDRAM cache. There should not be any big changes compared to the Iris Graphics 550.
The so called GT3e version of the Kaby Lake GPU probably still has 48 Execution Units (EUs), which can reach up to 1100 MHz depending on the model. Besides eDRAM cache, the Iris 650 can also access the system memory (2x 64 Bit DDR3L-1600/DDR4-2400) via processor interface.
Compared to the Iris Plus 640 from the 15-Watt models, the Iris 650 only has a slightly higher maximum clock as well as almost twice the TDP, which allows a better utilization of the Turbo Boost potential.
Performance
The exact performance of the Iris Plus Graphics 650 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 i7-7567U. Depending on the game, the Iris Plus 650 will probably be on par with a dedicated GeForce 930M 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 650 is used for 28-Watt processor and therefore medium-sized notebooks.
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.
