Frequently Asked Questions: Qwen 3.8 235B-A22B MoE on Apple Mac Studio M3 Ultra (256GB Unified Memory)
How much VRAM does Qwen 3.8 235B-A22B MoE need on Apple Mac Studio M3 Ultra (256GB Unified Memory)?
At standard 4-bit quantization (Q4_K_M) with 32K context, Qwen 3.8 235B-A22B MoE requires 149.84 GB of total VRAM (weights + KV cache + CUDA runtime overhead).
What inference speed will Qwen 3.8 235B-A22B MoE achieve on Apple Mac Studio M3 Ultra (256GB Unified Memory)?
Based on Apple Mac Studio M3 Ultra (256GB Unified Memory)'s 819 GB/s memory bandwidth, expected decode speed is approximately 37 tokens per second.
Can I expand context beyond 32K tokens?
Each additional 32K tokens of context requires additional KV cache memory. For longer context windows, consider 8-bit or 4-bit KV cache quantization.
