NVIDIA GeForce RTX 5090 vs NVIDIA RTX A4000, AI & Machine Learning Comparison
NVIDIA GeForce RTX 5090 wins 6 of 8 benchmarks, averaging 261.1% faster.
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 GeForce RTX 5090 leads by 302% (21.08 vs 5.24 images/min); the closest fight is Qwen3 4B (223% apart); VRAM decides part of this one: NVIDIA GeForce RTX 5090 runs 7 of our 12 AI workloads while the other card runs 4, models that don't fit score zero.
