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.

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).

Questions

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.

How many tokens per second does Qwen2.5-Coder-14B-Instruct get on an RTX 3090?

Decode speed measured by llm-speed, by quantization and runtime: Q4_K_M on llama.cpp: 78.2 tok/s. Based on 1 run measured by llm-speed; single-request chat-short unless noted. 1 community-submitted run is listed on the page, labelled, and not counted here.

What is the fastest quant of Qwen2.5-Coder-14B-Instruct that fits on an RTX 3090?

Q4_K_M on llama.cpp was the fastest measured setting at 78.2 tok/s; it fit because it ran. Other quants are listed only where a run measured them.

How much VRAM does Qwen2.5-Coder-14B-Instruct use on an RTX 3090?

Memory use was not recorded for these runs. The VRAM calculator gives an estimate, not a measurement.
