What hardware do I need to run Qwen3.6 35B-A3B?

35.9B MoE · 3.3B active 256K context Apache 2.0

At Q4_K_M the weights are 20.2 GB; with an 8K KV cache and runtime overhead that is 20.9 GB, so it wants a 32 GB card to run with headroom — in practice 32 GB VRAM: GeForce RTX 5090 and 2 others. Every figure below is computed from the model’s published shape against each device’s usable memory; tokens per second are estimates. The method.

Totals add 0.6 GB runtime overhead and an f16 KV cache; "needs" is the smallest discrete card class whose usable memory (after display and driver reserve) leaves 15% headroom. A q8_0 cache roughly halves the KV columns.
