Radeon HD 6630M Game Requirement Analysis
Radeon HD 6630M is a fast-middle-class GPU based on the 40nm Terrascale 2 architecture.
It's based on the Turks Core (therefore related to Radeon HD 6670) and offers 480 Shader Processing Units, 24 TMUs and 8 ROPs on a 128-bit memory interface of standard DDR3. Its central clock runs at 485MHz and the memory clock operates at 800MHz.
Compared to both Radeon HD 6650M and Radeon HD 6730M, it's heavily underclocked and performs much worse.
Using a 720p resolution, practically all of today's games are only playable at medium settings but with very fluent frame rates (40+).
