Apple reshapes desktop Macs with M6 and M5 Ultra

Apple has launched Mac mini models with M6 or M5 Pro chips and Mac Studio models with M5 Max or M5 Ultra. The refresh raises local-AI performance and memory-bandwidth ceilings while also lifting the Mac mini’s U.S. starting price by $300 versus the 2024 M4 model.

Apple has formally refreshed both desktop Mac lines: Mac mini now comes with M6 or M5 Pro, while Mac Studio offers M5 Max and M5 Ultra. This is more than a routine silicon update. It moves Apple’s desktop local-AI proposition toward higher memory bandwidth and a higher price tier, particularly for users running large models, video production and complex development workflows.

A new desktop segmentation takes shape

Apple says the new Mac mini comes in M6 and M5 Pro configurations, with preorders in mainland China beginning August 27 and sales starting September 22. Mac Studio now comes with M5 Max or M5 Ultra. The top M5 Ultra configuration reaches a 36-core CPU, 80-core GPU, 512GB of unified memory and 1.2TB/s of memory bandwidth; the 512GB version is expected in late October. Compared with the 2025 Mac Studio’s M3 Ultra, the headline change is not a doubling of GPU core counts, but a combined advance in CPU resources, memory bandwidth and architecture.

Local AI shifts toward memory and bandwidth constraints

Apple positions M5 Ultra for on-device AI and exceptionally demanding professional workflows, claiming up to 4.3 times the peak AI performance of M3 Ultra. It also cites LM Studio testing in which prompt processing can be up to four times faster than the prior generation. For local-model users, 512GB of unified memory and 1.2TB/s of bandwidth expand the size of models that can be accommodated and driven efficiently. The actual benefit, however, will depend on model quantization, inference-software optimization and workload characteristics. The M6 Mac mini extends this performance ladder to smaller desktop systems.

The performance update also resets the entry price

The new M6 Mac mini starts at $899 in the U.S. MacRumors reports that this is $300 above the $599 starting price of the 2024 M4 version; the M5 Pro model starts at $1,699 and the M5 Max Mac Studio at $2,499. The shift means Apple is not expanding local-AI desktop access solely through a lower entry point. It is raising the ceiling while increasing the cost of entry. Apple’s performance comparisons are primarily company measurements, so cross-platform value will still require independent testing.

What to watch next

The next evidence to watch is independent testing of M6 and M5 Ultra on local-model throughput, long-context workloads and energy use; delivery timing and enterprise demand for the 512GB Mac Studio; and whether Apple connects these capabilities more deeply to developer tools, Apple Intelligence or agent-oriented system functions. Strong benchmark gains paired with weak demand for high-priced configurations would limit the refresh’s broader effect on local AI.
