Written by Jakub Rusinowski · Last updated July 12, 2026
No — Qwen 3.6 27B at Q4_K_M needs 19.3 GB at 8K context (16.8 GB weights + 2.5 GB KV cache/overhead), and the NVIDIA GeForce RTX 3080 (10GB)'s 10 GB leaves it ~9.3 GB short. The cheapest card that runs it is the AMD Radeon RX 7900 XT (20 GB).

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 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 19.3 GB ✗ · 32K 24.6 GB ✗ · 128K 45.5 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.
