Can an RTX 3090 run Qwen2.5-Coder-14B-Instruct?
Yes: an RTX 3090 runs Qwen2.5-Coder 14B at 78.2 tok/s at Q4_K_M, measured on llama.cpp with a 131-token prompt in October 2026.
2 signed runs on llm-speed. Single-request decode speed in tokens per second; the short-chat workload unless noted. 1 of 2 runs were measured by llm-speed (@llmspeed); the other one is community-submitted (signed on the submitter's own machine, not measured by llm-speed, and not used for llm-speed verdicts). Runs measured by llm-speed are credited to @llmspeed. Verdicts and headline numbers use only llm-speed's own runs and fit tests.
Measured tok/s by quant and runtime
| Quant | Runtime | Build | Decode tok/s (best run) | Workload | Runs | Source |
|---|---|---|---|---|---|---|
| Q4_K_M | llama.cpp | commit ea0c4c2 | 78.2 | chat-short | 1 | Measured by llm-speed@llmspeed |
| Q4_K_M | ollama | 0.31.1 | 69.2 | chat-short | 1 | Community-submitted |
Fastest quant that fits: Q4_K_M on llama.cpp, 78.2 tok/s (measured by llm-speed; it fits because it ran on this hardware). Quants without a run are not listed.
VRAM: not recorded for these runs. The VRAM calculator gives an estimate (predicted, not measured).
