| 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 | 30 GB | 31.8 GB | Tight | ~34 tok/s |
| 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 Qwen3.8-27B-OBLITERATED?
Yes. Qwen3.8-27B-OBLITERATED 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 Q8_0 if you want higher quality.
How much VRAM does Qwen3.8-27B-OBLITERATED need?
About 16 GB of weights at Q4_K_M, 30 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 Qwen3.8-27B-OBLITERATED 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.
