Can I Run Qwen 2.5 14B Instruct on NVIDIA GeForce RTX 3070 Ti?
Written by Jakub Rusinowski · Last updated September 29, 2026
Not at Q4_K_M — that needs 10.9 GB at 8K context and the NVIDIA GeForce RTX 3070 Ti has 8 GB. Drop to Q2_K and it fits in 7 GB, with up to 8K of context.

Qwen 2.5 14B Instruct on the NVIDIA GeForce RTX 3070 Ti: 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 8 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 3070 Ti: 8K 10.9 GB ✗ · 32K 15.7 GB ✗ · 128K 35 GB ✗. Past 8K it no longer fits 8 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.
