Can the RTX 3050 OEM run Llama 3.1 8B?
Just. Llama 3.1 8B at Q4_K_M needs about 7.3 GB of the RTX 3050 OEM's 8 GB, running at an estimated 23 tok/s. Keep context short and close other GPU apps.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 5.5 GB | 7.3 GB | Tight | ~23 tok/s |
| Q5_K_M | 7 GB | 8.8 GB | Too big | - |
| Q8_0 | 10 GB | 11.8 GB | Too big | - |
| FP16 | 16 GB | 17.8 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 3050 OEM's 224 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.

Frequently asked
Quick answers
Can the GeForce RTX 3050 OEM run Llama 3.1 8B?
Just. Llama 3.1 8B at Q4_K_M needs about 7.3 GB of the RTX 3050 OEM's 8 GB, running at an estimated 23 tok/s. Keep context short and close other GPU apps.
How much VRAM does Llama 3.1 8B need?
About 5.5 GB of weights at Q4_K_M, 10 GB at Q8_0 and 16 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is Llama 3.1 8B on the RTX 3050 OEM?
Roughly 23 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the RTX 3050 OEM's 224 GB/s memory bandwidth.
