Written by Jakub Rusinowski · Last updated September 29, 2026
Yes, but it's tight — Qwen 3.7 35B-A3B at Q4_K_M needs 23.8 GB at 8K context (21.1 GB weights + 2.7 GB KV cache/overhead), leaving ~0.2 GB of the NVIDIA GeForce RTX 4090's 24 GB, at ~193 tok/s (est.), with room for up to 8K context.

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 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 4090: 8K 23.8 GB · 32K 29.4 GB ✗ · 128K 52 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.
