Radeon HD 8570D Game Requirement Analysis
Radeon HD 8570D is an embedded Graphics Card on the mainstream Richland APUs A8-6600 and A8-6600K.
They offer 256 Shader Processing Units, 16 TMUs and 8 ROPs. The memory interface depends on whether or not the system's RAM is dual channelled.
While the central unit runs at 844MHz (for 6600K, 800MHz for 6600), since the GFX doesn't have dedicated memory, the bandwidth will depend on the system ram speed which can be up to 1866MHz (the max speed supported by the CPU). Therefore, the max operating memory clock is 933MHz.
Its performance is slightly worse than Intel HD 4600 and only very slightly better than previous Radeon HD 7560D.
