Can the RTX 5090 run Qwen3.6 27B?
Yes. Qwen3.6 27B fits the RTX 5090's 32 GB at Q4_K_M (about 17.8 GB needed), running at an estimated 64 tok/s. There's room for up to Q5_K_M if you want higher quality.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 16 GB | 17.8 GB | Fits easily | ~64 tok/s |
| Q5_K_M | 20 GB | 21.8 GB | Fits | ~51 tok/s |
| Q8_0 | 31 GB | 32.8 GB | Too big | - |
| FP16 | 56 GB | 57.8 GB | Too big | - |
Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the RTX 5090's 1792 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.

Frequently asked
Quick answers
Can the NVIDIA RTX 5090 run Qwen3.6 27B?
Yes. Qwen3.6 27B fits the RTX 5090's 32 GB at Q4_K_M (about 17.8 GB needed), running at an estimated 64 tok/s. There's room for up to Q5_K_M if you want higher quality.
How much VRAM does Qwen3.6 27B need?
About 16 GB of weights at Q4_K_M, 31 GB at Q8_0 and 56 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is Qwen3.6 27B on the RTX 5090?
Roughly 64 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the RTX 5090's 1792 GB/s memory bandwidth.
