FAQ
- What are the main hardware differences between NVIDIA GeForce RTX 4070 and NVIDIA L4?
- NVIDIA GeForce RTX 4070 has 12GB VRAM and a 200W TDP, while NVIDIA L4 has 24GB VRAM and a 72W TDP.
- Does VRAM matter more than speed between NVIDIA GeForce RTX 4070 and NVIDIA L4?
- For AI, yes, NVIDIA GeForce RTX 4070 fits 16 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 GeForce RTX 4070 and NVIDIA L4?
- Qwen2.5-Coder 14B: NVIDIA GeForce RTX 4070 leads by roughly 85% (50.74 vs 27.46 tok/s) in our testing.
