Qwen 3 32B on the NVIDIA GeForce RTX 3090: 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 24 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 3090: 8K 22.8 GB · 32K 29.2 GB ✗ · 125K 54.2 GB ✗. Past 32K it no longer fits 24 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.

No compatible GPU? Qwen 3 32B on 32 GB of system RAM, CPU only: runs comfortably.
