FAQ
- Which is better for ai & machine learning: NVIDIA L40S or NVIDIA Titan RTX?
- NVIDIA L40S performs better for ai & machine learning, winning 11 of 11 benchmarks in our suite with an average 53.2% advantage.
- What are the main hardware differences between NVIDIA L40S and NVIDIA Titan RTX?
- NVIDIA L40S has 48GB VRAM and a 350W TDP, while NVIDIA Titan RTX has 24GB VRAM and a 280W TDP.
- Does VRAM matter more than speed between NVIDIA L40S and NVIDIA Titan RTX?
- For AI, yes, NVIDIA Titan RTX fits 4 more of our 12 workloads than NVIDIA L40S. 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 L40S and NVIDIA Titan RTX?
- Stable Diffusion XL: NVIDIA L40S leads by roughly 159% (17.02 vs 6.56 images/min) in our testing.
