How much VRAM does Qwen3.5-122B-A10B need at each quantization?

Qwen3.5-122B-A10B needs 83.0 GB of VRAM at Q4_K_M. The table below lists weights-only size and total VRAM including overhead for each common quantization level with 4k and 32k token contexts.

Method: weights = parameters × bits-per-weight (Q4_K_M ≈ 4.8, Q5_K_M ≈ 5.7, Q6_K ≈ 6.6, Q8_0 ≈ 8.5, FP16 = 16), plus 10% loading overhead, plus KV cache from the verified architecture config (48 layers, 2 KV heads, 256 head dim).

Runs Qwen3.5-122B-A10B comfortably (25%+ VRAM headroom)

Minimum GPUs that fit Qwen3.5-122B-A10B at Q4_K_M

These GPUs hold the model but leave little headroom — keep contexts short.

Needs 2+ GPUs to run Qwen3.5-122B-A10B

One of these cards is too small on its own, but a pair (tensor or pipeline parallel, ~90% efficiency) covers the 83.0 GB requirement. See our multi-GPU guide for setup.

Can a Mac run Qwen3.5-122B-A10B?

Yes — these Apple Silicon machines fit Qwen3.5-122B-A10B at Q4_K_M, since macOS lets the GPU use about 75% of unified memory. Generation speed is bound by memory bandwidth, so the GB/s column matters as much as capacity.

Can Qwen3.5-122B-A10B run on mini PCs, Jetson, or NPU devices?

These edge and NPU devices from our database have enough memory for Qwen3.5-122B-A10B at Q4_K_M. Their memory bandwidth is far below discrete GPUs, so expect a fraction of desktop generation speed.

Which pre-built systems can run Qwen3.5-122B-A10B?

These mini PCs and workstations from our database fit Qwen3.5-122B-A10B at Q4_K_M. Usable-memory figures are conservative: Windows shares about half of system RAM with the GPU by default (Linux can expose more), macOS lets Apple Silicon GPUs use about 75% of unified memory, and Linux unified-memory systems such as GB10 expose roughly 90%. Generation speed is bound by memory bandwidth, so compare the GB/s column before buying.
