FirePro S7000 Game Requirement Analysis
FirePro S7000 is a server GPU based on the 28nm GCN architecture.
It's based on the Pitcairn XT Core (same used on 7870) and therefore offers 1280 Shader Processing Units, 80 TMUs and 32 ROPs on a 256-bit interface of fast GDDR5. The central unit is clocked 950MHz while the memory clock operates at 1200MHZ.
Compared to Radeon HD 7870, its central unit is slightly lower clocked and its gaming performance is even lower as Radeon HD 7870 benefits from certified gaming drivers which unlock the GCN's architecture potential while FirePro S7000 is made for professional applications. Therefore, expect its performance to be between 10% and 15% worse than Radeon HD 7870.
