AMD’s Radeon 6700 XT is the closest PC GPU match for Xbox Series X, based on specs and performance, but it is not a direct equivalent. The Xbox GPU has 52 RDNA 2 compute units and about 12 TFLOPS; the 6700 XT has 40 CUs and higher clocks.
Clock and memory designs differ: the Xbox GPU runs at 1.825 GHz and draws from a 16GB unified pool shared with the CPU and system; the 6700 XT runs at a 2.321 GHz game clock, with boost up to 2.581 GHz, and has 12GB of dedicated VRAM. These differences make on-paper specs an imperfect guide to performance.
The article notes that developers can optimize games for the Xbox’s fixed hardware, while PCs span many configurations and software layers. Both GPUs support hardware ray tracing and AMD FidelityFX Super Resolution, but differ in areas including cache and memory bandwidth.
