Which is better for ai & machine learning: NVIDIA A100 80GB PCIe or NVIDIA L4?

NVIDIA A100 80GB PCIe performs better for ai & machine learning, winning 11 of 11 benchmarks in our suite with an average 233.9% advantage.

What are the main hardware differences between NVIDIA A100 80GB PCIe and NVIDIA L4?

NVIDIA A100 80GB PCIe has 80GB VRAM and a 300W TDP, while NVIDIA L4 has 24GB VRAM and a 72W TDP.

Does VRAM matter more than speed between NVIDIA A100 80GB PCIe and NVIDIA L4?

For AI, yes, NVIDIA A100 80GB PCIe fits 24 more of our 12 workloads than NVIDIA L4. 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 A100 80GB PCIe and NVIDIA L4?

Wan 2.2 5B (720p): NVIDIA A100 80GB PCIe leads by roughly 46% (0.61 vs 0.15 frames/s) in our testing.

NVIDIA A100 80GB PCIe vs NVIDIA L4, AI & Machine Learning Comparison

NVIDIA A100 80GB PCIe wins 11 of 11 benchmarks, averaging 233.9% faster.

Both cards were measured first-party on our bench, same suite, same test rig.

What the numbers say

The gap is widest in Wan 2.2 5B (720p), where NVIDIA A100 80GB PCIe leads by 307% (0.61 vs 0.15 frames/s); the closest fight is Qwen3 4B (136% apart); VRAM decides part of this one: NVIDIA A100 80GB PCIe runs 138 of our 12 AI workloads while the other card runs 12, models that don't fit score zero.
