Radeon HD 6550D Review
Radeon HD 6550D is an integrated GPU in one of AMD's processors. It's part of the high-end class GPUS of this Series. It supports DirectX 11 and uses system memory and it only supports DDR3-1866 memory type.
The performance, is obviously, limited but demanding games should still be playable from low to medium settings (depending on the resolution + DirectX version used), while very demanding games might not run at all or might require very reduced settings.
All in all, even though it supports DirectX 11, most likely games that use it are unplayable to the lowest settings or only playable on the lowest settings because every game out there using DirectX 11 is either demanding or very demanding.
