FirePro W8000 Game Requirement Analysis
FirePro W8000 is a server GPU based on the 28nm GCN architecture.
It's based on the Tahiti Pro Core (same used on 7950) and therefore offers 1792 Shader Processing Units, 112 TMUs and 32 ROPs on a 256-bit interface of fast GDDR5. The central unit is clocked at 900MHz while the memory clock operates at 1375MHZ.
Compared to Radeon HD 7950, its central unit is slightly higher clocked but comes equipped with a 256-bit bus width (against 7950's 384-bit) and so it features less memory bandwidth.
Overall, its gaming performance is considerably lower than Radeon HD 7950 because Radeon HD 7950 benefits from certified gaming drivers which unlock the GCN's architecture potential while FirePro W8000 is made for professional applications. Therefore, expect its performance to be between 10% and 15% worse than Radeon HD 7950.
