Methodology
Graphics cards are compared on 3DMark Time Spy scores, average gaming frame rates at 1080p/1440p/4K, FP32 compute throughput, VRAM capacity and type, memory bandwidth, board power (TDP) and launch MSRP — plus AI workload throughput (Stable Diffusion iterations/s and local LLM tokens/s) where measured. Vintage and server GPUs without modern benchmark results are compared on specifications only, clearly labelled. Frame rates are averages across a game suite at high settings; specific titles vary.
