Radeon HD 6990M Game Requirement Analysis
Radeon HD 6990M is a high-end GPU based on the 40nm Terrascale 2 architecture and not a dual-graphics solution, despite its naming.
It's based on the Barts Core (therefore related to Radeon HD 6870) and offers 1120 Shader Processing Units, 56 TMUs and 32 ROPs on a 256-bit memory interface of fast GDDR5. Its central clock runs at 715MHz and the memory clock operates at 900MHz.
Despite being based on the same Core used on Radeon HD 6870, its performance is more comparable to Radeon HD 6850 due to being heavily underclocked.
Today's modern games are playable at the highest settings but a few exceptions will require lower resolutions or modest presets to be played optimally.
