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 A4500 leads by 56% (4.18 vs 6.5 images/min); the closest fight is Qwen3 4B (0% apart); VRAM decides part of this one: NVIDIA RTX A4500 runs 6 of our 12 AI workloads while the other card runs 3, models that don't fit score zero.
