Apple Mac Studio M5 Ultra
From $5,499
Up to 512GB of unified memory at 1.2TB/s — double the M3 Ultra ceiling, and the first single silent desktop that holds frontier-scale MoE models entirely in memory. This is a capability purchase, not a value one: nothing else in the Apple lineup comes close, and nothing else needs to.

The Ryzen AI Max+ PRO 495 raises unified memory 50% to 192GB but bandwidth only 6.6%, to 273 GB/s, with the same 40 RDNA 3.5 compute units. Here's the arithmetic that decides whether you wait for 192GB or buy a 128GB Strix Halo box today.
How to Run Mistral Large 4 Locally (2026): The Hardware It Actually Takes — Before the Weights Drop
Mistral Large 4 is a ~1.05T-parameter multimodal MoE with 52B active parameters, and the open weights are due by October 31. At 4-bit it needs roughly 635GB of memory. Here's the full quant-size table, the bandwidth math that sets your tokens per second, the four hardware paths that can actually hold it (512GB Mac Studio, GPU + RAM offload, a Spark/Strix cluster, an 8-GPU server), and the honest offramp for everyone else.
