FAQ
- Which is better for ai & machine learning: NVIDIA H200 or NVIDIA RTX A6000?
- NVIDIA H200 performs better for ai & machine learning, winning 9 of 9 benchmarks in our suite with an average 208% advantage.
- What are the main hardware differences between NVIDIA H200 and NVIDIA RTX A6000?
- NVIDIA H200 has 141GB VRAM and a 700W TDP, while NVIDIA RTX A6000 has 48GB VRAM and a 300W TDP.
- Does VRAM matter more than speed between NVIDIA H200 and NVIDIA RTX A6000?
- For AI, yes, NVIDIA RTX A6000 fits 2 more of our 12 workloads than NVIDIA H200. 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 H200 and NVIDIA RTX A6000?
- FLUX.1 dev: NVIDIA H200 leads by roughly 340% (9.514 vs 2.164 images/min) in our testing.
