MagyarAMD Radeon HD 8570D vs AMD Radeon HD 8470D
AMD Radeon HD 8570D
► remove
The AMD Radeon HD 8570D is a processor graphics card in the desktop Richland A8 series of APUs from AMD (e.g. A8-6600K). It is the second fastest model of its family and is based on the VLIW4 architecture of the Radeon HD 6900 desktop series. Compared to the faster HD 8670D, the 8570D features much less shader cores (384 vs. 256 cores). The graphics card features no dedicated graphics memory and thus depends on the speed and size of the system memory.
The performance of the Radeon HD 8570D differs depending on the benchmark. In synthetic benchmarks like 3DMark 11, final scores suggest better gaming performance when in practice the frame rates are slightly lower. In our gaming tests the HD 8570D was similar to the fastest Trinity desktop model, the Radeon HD 7660D, which features more shader cores at lower clock speeds. Demanding games like Crysis 3 are therefore only playable in low details and resolutions (see below).
The integrated UVD3 video decoder (Avivo HD) allows full decoding of Multi-View Codec (MVC), MPEG-4 Part 2 (DivX, xVid), MPEG-4 AVC/H.264 and Adobe Flash HD videos.
The shader cores of the chip can also be used for general computing via OpenCL or DirectCompute 11.
AMD Radeon HD 8470D

The AMD Radeon HD 8470D is a processor graphics card featured in the desktop Richland A6 series of APUs from AMD and is based on the VLIW4 architecture of the Radeon HD 6900 desktop series. Compared to the faster HD 8670D, the 8470 features only 128 of the 384 cores clocked at 800 MHz compared to 844 MHz of the 8670D. The graphics card does not offer dedicated video memory and thus depends on the speed and size of the system memory.
The performance of the Radeon HD 8470D differs depending on the benchmark. In synthetic benchmarks like 3DMark 11, final scores suggest better gaming performance when in practice the frame rates are slightly lower. In our gaming tests the HD 8470D was similar to the Trinity Radeon HD 7660G in the mobile A10-4600M and comparable to the average HD Graphics 4000 on Ivy Bridge chips. Therefore, very demanding games like Company of Heroes 2 will not run fluently on the APU (see below for detailed benchmarks).
