FirePro V5800 Game Requirement Analysis
FirePro V5800 is a professional graphics card based on the 40nm Terascale 2 architecture.
It's based on the Juniper XT Core (same used on Radeon HD 6770) and therefore offers 800 Shader Processing Units, 40 TMUs and 16 ROPs on a 128-bit interface of fast GDDR5. The central unit is clocked 700MHz while the memory clock operates at 1000MHZ.
Compared to Radeon HD 6770, its central unit is underclocked and overall its gaming performance is even lower than Radeon HD 6770 because the latter benefits from certified gaming drivers which unlock the Terascale's architecture potential while FirePro W5800 is made for professional applications. Therefore, expect its performance to be between 7% and 10% worse than Radeon HD 6770.
