Can I Run Qwen 3 32B on NVIDIA GeForce RTX 4070 Ti Super?
作者： Jakub Rusinowski · 最后更新： 2026年9月19日
Not at Q4_K_M — that needs 19.8 GB and the NVIDIA GeForce RTX 4070 Ti Super has 16 GB. Drop to Q2_K and it fits in 13.7 GB, with up to 8K of context.

Qwen 3 32B on the NVIDIA GeForce RTX 4070 Ti Super: VRAM by quantization

Assumes a 4K-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 NVIDIA GeForce RTX 4070 Ti Super: 8K 22.8 GB ✗ · 32K 29.2 GB ✗ · 125K 54.2 GB ✗. Past 8K it no longer fits 16 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Quantize to Q2_K. That is the cheapest fix — it costs some quality but no money.
