No. Qwen3-Next 80B-A3B (MoE) does not fit on RTX 3090 24GB: Q4_K_M needs 52.4 GB and 23.5 GB is usable.
Hardware: RTX 3090 24GB · Model: Qwen3-Next 80B-A3B (MoE)
RTX 3090 24GB has 24 GB of VRAM and 936 GB/s of memory bandwidth. The checker holds back 0.5 GB of VRAM for the driver and assumes 16 GB of system RAM, so fast memory usable by Ollama is 23.5 GB. Partial offload may also use 60% of that system RAM. Qwen3-Next 80B-A3B (MoE) (80B, 3B active, Alibaba) at Q4_K_M is a 50 GB download and needs 52.4 GB with headroom for about 8k tokens.

Smallest hardware that runs it: M1 Max (32c GPU) 64GB at Q4_K_M (fits if the Mac GPU limit is raised, 52.4 GB needed, 48.0 GB usable, about 85 tok/s (estimate)). Can a M1 Max (32c GPU) 64GB run Qwen3-Next 80B-A3B (MoE)?
A smaller Alibaba model that fits this hardware: Qwen3.5 35B-A3B (MoE) at Q4_K_M (partial offload (slower), 23.9 GB). Can a RTX 3090 24GB run Qwen3.5 35B-A3B (MoE)?
