FAQ & Reference

Frequently Asked Questions: Qwen 3.6 35B-A3B MoE on Apple Mac Studio M2 Ultra (192GB Unified Memory)

How much VRAM does Qwen 3.6 35B-A3B MoE need on Apple Mac Studio M2 Ultra (192GB Unified Memory)?

At standard 4-bit quantization (Q4_K_M) with 32K context, Qwen 3.6 35B-A3B MoE requires 24.1 GB of total VRAM (weights + KV cache + CUDA runtime overhead).

What inference speed will Qwen 3.6 35B-A3B MoE achieve on Apple Mac Studio M2 Ultra (192GB Unified Memory)?

Based on Apple Mac Studio M2 Ultra (192GB Unified Memory)'s 800 GB/s memory bandwidth, expected decode speed is approximately 236 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.
