Can the RTX 5090 run Laguna-XS-2.1?
Yes. Laguna-XS-2.1 fits the RTX 5090's 32 GB at Q4_K_M (about 20.8 GB needed), running at an estimated 54 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 | 19 GB | 20.8 GB | Fits | ~54 tok/s |
| Q5_K_M | 24 GB | 25.8 GB | Fits | ~43 tok/s |
| Q8_0 | 36 GB | 37.8 GB | Too big | - |
| FP16 | 67 GB | 68.8 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 Laguna-XS-2.1?
Yes. Laguna-XS-2.1 fits the RTX 5090's 32 GB at Q4_K_M (about 20.8 GB needed), running at an estimated 54 tok/s. There's room for up to Q5_K_M if you want higher quality.
How much VRAM does Laguna-XS-2.1 need?
About 19 GB of weights at Q4_K_M, 36 GB at Q8_0 and 67 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is Laguna-XS-2.1 on the RTX 5090?
Roughly 54 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.
