Mac Studio Dilemma: M5 Ultra Bandwidth vs M5 Max RAM for Qwen3.8
Mxmtm · reddit · 2026-08-26
A user debates between M5 Ultra (96GB) and M5 Max (128GB) Mac Studio configs. The Ultra offers double bandwidth and GPU cores, accelerating the current Qwen3.8-27B Q8 workload, but lacks the RAM to run the upcoming 176B MoE Qwen3.8-Flash-Next, which fits on the Max. The analysis weighs memory constraints against bandwidth utility, especially for MoE models with low active parameters, and seeks advice on multi-agent performance, quantization limits, and resale value.
