Can I Run Qwen 2.5 Coder 32B on NVIDIA L40S?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 21 lipca 2026
Yes. Qwen 2.5 Coder 32B needs 22.3 GB at 8K context (19.3 GB weights + 3 GB KV cache/overhead) at Q4_K_M and the NVIDIA L40S has 48 GB, leaving about 25.7 GB of headroom, at roughly 36 tok/s (estimated) with room for up to 64K of context.

Qwen 2.5 Coder 32B on the NVIDIA L40S: VRAM by quantization

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 48 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 NVIDIA L40S: 8K 22.3 GB · 32K 28.7 GB · 128K 54.5 GB ✗. Past 128K it no longer fits 48 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.
