FirePro D500 Game Requirement Analysis
FirePro D500 is a workstation Graphics Card based on the 28nm GCN architecture.
It's based on the Tahite LE Core (same used on Radeon HD 7870 XT) and therefore offers 1536 Shader Processing Units, 96 TMUs and 32 ROPs, but on a 384-bit interface of fast GDDR5. The central unit is clocked 725MHz while the memory clock operates at 1250MHZ.
It is thus considerably lower clocked and its gaming performance is even lower, as Radeon HD 7870 XT benefits from certified gaming drivers which unlock the GCN's architecture potential while FirePro D500 is made for professional applications. Therefore, expect its performance to be similar to Radeon HD 7870.
