Can I Run Yi 1.5 9B Chat on AMD Radeon RX 9060 XT 8GB?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 12 lipca 2026
Yes. Yi 1.5 9B Chat needs 6.9 GB at 8K context (5.3 GB weights + 1.6 GB KV cache/overhead) at Q4_K_M and the AMD Radeon RX 9060 XT 8GB has 8 GB, leaving about 1.1 GB of headroom, at roughly 34 tok/s (estimated) with room for up to 16K of context.

Yi 1.5 9B Chat on the AMD Radeon RX 9060 XT 8GB: VRAM by quantization
| Quant | VRAM needed | Fits 8 GB? | Max context | Whole PC |
|---|---|---|---|---|
| F16 | 19.3 GB | ✗ No | — | — |
| Q8_0 | 11 GB | ✗ No | — | — |
| Q6_K | 8.8 GB | ✗ No | — | — |

| Q4_K_M | 6.9 GB | ✓ Yes | 16K | — |

| Q2_K | 4.5 GB | ✓ Yes | 16K | — |
Assumes an 8K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 8 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 9060 XT 8GB: 8K 6.9 GB · 31K 9.3 GB ✗. Past 31K it no longer fits 8 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
