NVIDIA L4 vs NVIDIA RTX A4000, AI & Machine Learning Comparison
NVIDIA RTX A4000 wins 4 of 10 benchmarks, averaging 34.8% faster.
Both cards were measured first-party on our bench, same suite, same test rig.
What the numbers say
The gap is widest in Qwen2.5-Coder 14B, where NVIDIA RTX A4000 leads by 50% (27.46 vs 41.13 tok/s); the closest fight is Stable Diffusion XL (1% apart); VRAM decides part of this one: NVIDIA RTX A4000 runs 138 of our 12 AI workloads while the other card runs 4, models that don't fit score zero.

FAQ
- Which is better for ai & machine learning: NVIDIA L4 or NVIDIA RTX A4000?
- NVIDIA RTX A4000 performs better for ai & machine learning, winning 4 of 10 benchmarks in our suite with an average 34.8% advantage.
- What are the main hardware differences between NVIDIA L4 and NVIDIA RTX A4000?
- NVIDIA L4 has 24GB VRAM and a 72W TDP, while NVIDIA RTX A4000 has 16GB VRAM and a 140W TDP.
- Does VRAM matter more than speed between NVIDIA L4 and NVIDIA RTX A4000?
- For AI, yes, NVIDIA RTX A4000 fits 18 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 L4 and NVIDIA RTX A4000?
- Qwen2.5-Coder 14B: NVIDIA RTX A4000 leads by roughly 50% (27.46 vs 41.13 tok/s) in our testing.
