AMD Pro A12-8800B | AMD Radeon R7 (Carrizo) | 14.00" | 1.6 kg
The AMD Radeon R7 (Carrizo) is an integrated graphics card in the fastest Carrizo APUs. At launch in mid 2015 the R7 was used in the AMD FX-8800P SoC with 512 GCN shaders and 800 MHz clock rate (Boost?). Depending on the configured TDP (ranging from 12 to 35 Watt) and used main memory (up to DDR3-2133 in dual channel mode supported) the performance can differ greatly.
The Radeon R7 is using the third generation GCN architecture (sometimes also called GCN 1.2) similar to the desktop Tonga chip. Therefore, it offers DirectX 12 (FL 12_0) hardware support and advanced color compression that leads to 5-7% improvement in games. Furthermore, the shaders can be used with Mantle, OpenGL and OpenCL. HSA 1.0 is supported to easily run code on CPU and GPU cores together.
The improved video decoder UVD 6 (Unified Video Decoder) is now able to decode HVEC / H.265 in up 4K in hardware. Furthermore, the VCE (Video Codec Engine) was improved for faster transcodes of H.264.
More information on architecture and features of the Carrizo chips can be found in our launch article.
The gaming performance of the integrated R7 depends on the configured TDP (12 - 35 Watt) of the chip. AMD e.g. published 3DMark 11 scores of a 15 and 35 Watt version, where the 35 Watt version was 38% faster than the 15 Watt version. Demanding games like Evolve or Far Cry 4 will struggle to achieve fluent frame rates. However, less demanding games like Call of Duty: AW may even run in high detail settings (see the slightly slower Kaveri R7 GPU for benchmarks).
Depending on the configured TDP the chip may be used in thin and light machines (12 - 20 Watt range) or normal sized laptops (35 Watt TDP).
