RDNA 3 · 2022
The RX 7900 XTX introduced AMD's RDNA 3 architecture at the top end in 2022, built on a 5nm process with 6144 stream processors and a huge 24GB GDDR6 frame buffer across a 384-bit bus for 960GB/s of bandwidth - specs that rival far pricier professional cards. It positioned itself as AMD's answer to NVIDIA's RTX 4080.
Running at up to 2500 MHz boost and drawing 355W, it needs a high-wattage power supply and excellent case airflow - this is a flagship desktop card with no mobile equivalent. It handles 4K gaming at maximum settings in nearly everything, and the 24GB of VRAM gives it serious headroom for content creation and AI workloads too.
