GPU Fit Matrix
Can the RTX 3090 (used) run DeepSeek V3 0324?
No — this GPU does not have enough VRAM
Planning estimate: DeepSeek V3 0324 (685B total) needs about345 GB of VRAM at FP4(≈4K context). The RTX 3090 (used) has24 GB.
This is a computed planning estimate (parameter count × bytes/parameter × quantization + context overhead), not a measured benchmark. See how we estimate.
VRAM needed by quantization
| Quantization | Est. VRAM needed | Fits 24GB? |
|---|---|---|
| FP8 | 687.5 GB | ❌ No |
| FP4 | 345 GB | ❌ No |
No measured benchmark yet. We don't publish invented tokens/sec — when we have a first-party measured run for this pairing, it will appear here. For now this page is a VRAM planning estimate. Model the exact case in ourVRAM calculator.
