AMD Radeon R5 (Bristol Ridge) vs Intel HD Graphics P630

AMD Radeon R5 (Bristol Ridge)

The AMD Radeon R5 (Bristol Ridge) is an integrated graphics card for a number of mid-range mobile Bristol-Ridge-based APUs, such as those from the A10 series. It features 384 shader cores clocked at 720 MHz (15 Watt APUs) or 800 MHz (35 Watt APUs). Depending on the configurable TDP (set per laptop model) and the used main memory, the performance can also differ.

Architecture and Features

The Radeon R5 utilizes the third generation GCN architecture (sometimes referred to as GCN 1.2) similar to the desktop Tonga chip. As a result, it supports DirectX 12 (FL 12_0) with advanced color compression that leads to a 5-7% improvement in games. Furthermore, its shaders can be used with Mantle, OpenGL and OpenCL. HSA 1.0 is supported for running code on both CPU and GPU cores simultaneously. The improved video decoder UVD 6 (Unified Video Decoder) is now able to decode HVEC / H.265 up to 4K in hardware. Furthermore, the VCE (Video Codec Engine) has been improved for faster transcoding of H.264. More information on architecture and features of the Bristol Ridge architecture can be found in our launch article.

Performance

Gaming performance of the integrated R5 GPU depends on the configured TDP, model and main memory of the system. A typical ULV version with a TDP of 15 Watt paired with fast dual channel main memory is nearly on a level with the dedicated GeForce 920M or Radeon R7 M260 (see gaming benchmarks below). Therefore, demanding games of 2015 and 2016 may only run in the lowest detail settings fluently (and some not at all).

Power Consumption

Depending on the configured TDP, the still in 28 nm produced chip may be used in thin-and-light (12 - 20 Watt range) to standard-sized laptops (35 Watt TDP).

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.
