Which is better for ai & machine learning: NVIDIA A40 or NVIDIA H200?

NVIDIA H200 performs better for ai & machine learning, winning 9 of 9 benchmarks in our suite with an average 282.2% advantage.

What are the main hardware differences between NVIDIA A40 and NVIDIA H200?

NVIDIA A40 has 48GB VRAM and a 300W TDP, while NVIDIA H200 has 141GB VRAM and a 700W TDP.

Does VRAM matter more than speed between NVIDIA A40 and NVIDIA H200?

For AI, yes, NVIDIA A40 fits 2 more of our 12 workloads than NVIDIA H200. A model that exceeds VRAM doesn't run slower, it doesn't run at all, so the card that fits the model wins that workload outright.

Where is the biggest performance difference between NVIDIA A40 and NVIDIA H200?

Z-Image Turbo: NVIDIA H200 leads by roughly 619% (3.225 vs 23.175 images/min) in our testing.

NVIDIA A40 vs NVIDIA H200, AI & Machine Learning Comparison

NVIDIA H200 wins 9 of 9 benchmarks, averaging 282.2% faster.

NVIDIA A40's numbers are anchored estimates calibrated against our measured cards, pending first-party measurement. Treat small gaps as ties.

What the numbers say

The gap is widest in Z-Image Turbo, where NVIDIA H200 leads by 619% (3.225 vs 23.175 images/min); the closest fight is Qwen3 4B (98% apart); VRAM decides part of this one: NVIDIA A40 runs 150 of our 12 AI workloads while the other card runs 8, models that don't fit score zero.
