Radeon HD 3450 Game Requirement Analysis
Radeon HD 3450 is an entry-level GPU based on the 55nm, second unified shader architecture, R600.
It's based on the RV620 LE Core and offers 40 Shader Processing Units, 4 TMUs and 4 ROPs a 64-bit memory interface of standard DDR2. The central unit runs at 600MHz and the memory clock runs at up to 500MHz.
Its limited memory bandwidth makes today's games only playable at unattractive resolutions and using low (maybe) or medium presets. DirectX 11 games aren't supported.
