Which is better for ai & machine learning: NVIDIA GeForce RTX 3070 Ti or NVIDIA A100 80GB PCIe?

NVIDIA A100 80GB PCIe performs better for ai & machine learning, winning 12 of 12 benchmarks in our suite with an average 144.5% advantage.

What are the main hardware differences between NVIDIA GeForce RTX 3070 Ti and NVIDIA A100 80GB PCIe?

NVIDIA GeForce RTX 3070 Ti has 8GB VRAM and a 290W TDP, while NVIDIA A100 80GB PCIe has 80GB VRAM and a 300W TDP.

Does VRAM matter more than speed between NVIDIA GeForce RTX 3070 Ti and NVIDIA A100 80GB PCIe?

For AI, yes, NVIDIA A100 80GB PCIe fits 9 more of our 12 workloads than NVIDIA GeForce RTX 3070 Ti. 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 GeForce RTX 3070 Ti and NVIDIA A100 80GB PCIe?

Stable Diffusion XL: NVIDIA A100 80GB PCIe leads by roughly 347% (3.76 vs 16.8 images/min) in our testing.

NVIDIA GeForce RTX 3070 Ti vs NVIDIA A100 80GB PCIe, AI & Machine Learning Comparison

NVIDIA A100 80GB PCIe wins 12 of 12 benchmarks, averaging 144.5% 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 A100 80GB PCIe leads by 347% (3.76 vs 16.8 images/min); the closest fight is Qwen3 4B (28% apart); VRAM decides part of this one: NVIDIA A100 80GB PCIe runs 12 of our 12 AI workloads while the other card runs 3, models that don't fit score zero.
