Can I Run Qwen3-Coder-Next (80B-A3B MoE) on NVIDIA A100 80GB (PCIe)?
Written by Jakub Rusinowski · Last updated September 29, 2026
Yes. Qwen3-Coder-Next (80B-A3B MoE) needs 51.6 GB at 8K context (48.3 GB weights + 3.3 GB KV cache/overhead) at Q4_K_M and the NVIDIA A100 80GB (PCIe) has 80 GB, leaving about 28.4 GB of headroom, at roughly 209 tok/s (estimated) with room for up to 64K of context.

Assumes an 8K-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 80 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 A100 80GB (PCIe): 8K 51.6 GB · 32K 59 GB · 128K 88.8 GB ✗. Past 128K it no longer fits 80 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.
