Can I Run Qwen3-Coder on NVIDIA GeForce RTX 3080 (10GB)?
作者： Jakub Rusinowski · 最后更新： 2026年9月29日
No — Qwen3-Coder 30B-A3B (MoE) at Q4_K_M needs 20 GB at 8K context (18.4 GB weights + 1.6 GB KV cache/overhead), and the NVIDIA GeForce RTX 3080 (10GB)'s 10 GB leaves it ~10 GB short. The cheapest card that runs it is the AMD Radeon RX 7900 XT (20 GB).

Qwen3-Coder 30B-A3B (MoE) on the NVIDIA GeForce RTX 3080 (10GB): 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 10 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 GeForce RTX 3080 (10GB): 8K 20 GB ✗ · 32K 22.4 GB ✗ · 128K 32.1 GB ✗. Past 8K it no longer fits 10 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Qwen3-Coder 30B-A3B (MoE) on 16 GB of system RAM, CPU only: runs, but it is tight.
Why It Does Not Fit
Every Qwen3-Coder variant requires more VRAM than the NVIDIA GeForce RTX 3080 (10GB) provides (10 GB).
Nearest GPU That Fits
AMD Radeon RX 7900 XT (20 GB VRAM).
Qwen3-Coder needs ~20 GB but this GPU has 10 GB. Rent a RTX 4090 (24 GB)-class GPU by the hour instead of buying one:
