Which is better for ai & machine learning: GeForce RTX 5070 or NVIDIA A40?

NVIDIA A40 performs better for ai & machine learning, winning 6 of 9 benchmarks in our suite with an average 9.9% advantage.

What are the main hardware differences between GeForce RTX 5070 and NVIDIA A40?

GeForce RTX 5070 has 12GB VRAM and a 250W TDP, while NVIDIA A40 has 48GB VRAM and a 300W TDP.

Does VRAM matter more than speed between GeForce RTX 5070 and NVIDIA A40?

For AI, yes, NVIDIA A40 fits 8 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 A40?

Stable Diffusion XL: NVIDIA A40 leads by roughly 52% (6.06 vs 9.2 images/min) in our testing.

GeForce RTX 5070 vs NVIDIA A40, AI & Machine Learning Comparison

NVIDIA A40 wins 6 of 9 benchmarks, averaging 9.9% faster.

Both cards' 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 Stable Diffusion XL, where NVIDIA A40 leads by 52% (6.06 vs 9.2 images/min); the closest fight is Qwen3 4B (12% apart); VRAM decides part of this one: NVIDIA A40 runs 8 of our 12 AI workloads while the other card runs 3, models that don't fit score zero.
