Both cards were measured first-party on our bench, same suite, same test rig.
What the numbers say
The gap is widest in Stable Diffusion XL, where NVIDIA RTX A6000 leads by 140% (4.18 vs 10.02 images/min); the closest fight is Qwen3 4B (24% apart); VRAM decides part of this one: NVIDIA RTX A6000 runs 9 of our 12 AI workloads while the other card runs 3, models that don't fit score zero.
