Question: what graphics card does xbox one have?
Answer: The Xbox One is powered by an 8-core x86 AMD CPU (almost certainly based on AMD's Kabini), and a GPU that's very similar to the Radeon 7790. There's 8GB of DDR3 RAM (shared between the CPU and GPU), 32MB of very fast SRAM on the graphics die, and a total of 200GB of memory bandwidth (more on that later).
