AMD Radeon HD 8280 vs Intel HD Graphics P630

AMD Radeon HD 8280

The AMD Radeon HD 8280 is an integrated DirectX 11.1 graphics card typically paired with AMD Kabini-class APUs (for example, E2-3000). It offers 128 shader cores and two Compute Units based on the GCN architecture and is clocked at 450 MHz with no support for Turbo. The graphics card does not have dedicated VRAM and will access the main memory of the system (up to single-channel DDR3L-1600).

The HD 8280 integrates both UVD 4.2 and VCE 2.0 video encoders. It supports up to two external monitors via VGA, DVI, HDMI 1.4a and DisplayPort 1.2.

Depending on the benchmark, the performance of the Radeon HD 8280 is slightly below the Intel HD Graphics (Haswell). This is on par with a dedicated Radeon HD 7370M, but is still too slow for most demanding games as of 2013. However, some older and less demanding games should run fluently if the performance of the CPU is sufficient.

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.
