Can I Run StarCoder 2 15B on AMD Radeon RX 9070?
作者： Jakub Rusinowski · 最后更新： 2026年7月12日
Yes. StarCoder 2 15B needs 10.8 GB at 8K context (9.4 GB weights + 1.4 GB KV cache/overhead) at Q4_K_M and the AMD Radeon RX 9070 has 16 GB, leaving about 5.2 GB of headroom, at roughly 40 tok/s (estimated) with room for up to 16K of context.

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 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 10.8 GB · 16K 11.5 GB. Every window this model publishes still fits 16 GB.
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.
