Radeon HD 6570M Game Requirement Analysis
Radeon HD 6570M is a middle-class GPU based on the 40nm Terrascale 2 architecture.
It's based on the Redwood Core (therefore related to Radeon HD 5670) and offers 400 Shader Processing Units, 20 TMUs and 8 ROPs on a 128-bit memory interface of fast GDDR5. Its central clock runs at 650MHz and the memory clock operates at 800MHz.
Therefore, it's a renamed Mobility HD 5770 and it should perform better than both Radeon HD 6630M & Radeon HD 6650M.
Using a 720p resolution, most of today's games are only playable at medium or high settings but with very fluent frame rates (40+).
