InternLM 3 20B Instruct on the AMD Radeon RX 9070: VRAM by quantization
| Quant | VRAM needed | Fits 16 GB? | Max context | Whole PC |
|---|---|---|---|---|
| F16 | 41.6 GB | ✗ No | — | — |
| Q8_0 | 22.8 GB | ✗ No | — | Build for this |
| Q6_K | 18 GB | ✗ No | — | — |
| Q5_K_M | 15.8 GB | ✓ Yes | 4K | — |
| Q4_K_M | 13.7 GB | ✓ Yes | 8K | Build for this |

| Q2_K | 8.2 GB | ✓ Yes | 32K | — |
Assumes a 4K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 16 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the AMD Radeon RX 9070: 8K 14.5 GB · 32K 19.2 GB ✗. Past 32K it no longer fits 16 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
