Which is better for ai & machine learning: GeForce RTX 4060 or NVIDIA A40?

NVIDIA A40 performs better for ai & machine learning, winning 8 of 9 benchmarks in our suite with an average 139.9% advantage.

What are the main hardware differences between GeForce RTX 4060 and NVIDIA A40?

GeForce RTX 4060 has 8GB VRAM and a 115W TDP, while NVIDIA A40 has 48GB VRAM and a 300W TDP.

Does VRAM matter more than speed between GeForce RTX 4060 and NVIDIA A40?

For AI, yes, NVIDIA A40 fits 9 more of our 12 workloads than GeForce RTX 4060. 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 4060 and NVIDIA A40?

Stable Diffusion XL: NVIDIA A40 leads by roughly 231% (2.78 vs 9.2 images/min) in our testing.

GeForce RTX 4060 vs NVIDIA A40, AI & Machine Learning Comparison

NVIDIA A40 wins 8 of 9 benchmarks, averaging 139.9% 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 Stable Diffusion XL, where NVIDIA A40 leads by 231% (2.78 vs 9.2 images/min); the closest fight is Qwen3 4B (86% 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.
