Question: what graphics card does the xbox one x use?
Answer: The heart of the Xbox One X is a GPU that's roughly based on AMD's GCN 4 (Polaris) architecture. It offers 40 compute units, 2560 stream processors, and 32 ROPs. For comparison, an AMD Radeon RX 480 offers 36 CUs, so the Xbox One X offers 11% more compute hardware than the RX 480.
