Which is better for ai & machine learning: GeForce RTX 5070 or NVIDIA H100 80GB HBM3?

NVIDIA H100 80GB HBM3 performs better for ai & machine learning, winning 12 of 12 benchmarks in our suite with an average 220.4% advantage.

What are the main hardware differences between GeForce RTX 5070 and NVIDIA H100 80GB HBM3?

GeForce RTX 5070 has 12GB VRAM and a 250W TDP, while NVIDIA H100 80GB HBM3 has 80GB VRAM and a 700W TDP.

Does VRAM matter more than speed between GeForce RTX 5070 and NVIDIA H100 80GB HBM3?

For AI, yes, NVIDIA H100 80GB HBM3 fits 6 more of our 12 workloads than GeForce RTX 5070. 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 GeForce RTX 5070 and NVIDIA H100 80GB HBM3?

Stable Diffusion XL: NVIDIA H100 80GB HBM3 leads by roughly 471% (6.06 vs 34.58 images/min) in our testing.
