FirePro M4000 Game Requirement Analysis
FirePro M4000 is a Professional Graphics Card based on the 28nm GCN architecture.
It's based on the Cape Verde PRO Core (same used on 7750M & 7750) and therefore offers 512 Shader Processing Units, 32 TMUs and 16 ROPs on a 128-bit interface of fast GDDR5. The central unit is clocked 600MHz while the memory clock operates at 1000MHZ.
Compared to Radeon HD 7750M, its central unit is slightly higher clocked but overall its gaming performance is identical to Radeon HD 7750M because the latter benefits from certified gaming drivers which unlock the GCN's architecture potential while FirePro M4000 is made for professional applications.
