Apple announced two chips on August 25: M6 for the new Mac mini and M5 Ultra for the new Mac Studio. M5 Ultra joins two dual-die M5 Max chips into Apple's first quad-die design, with up to 80 GPU cores, up to 512 GB of unified memory and up to 1.2 TB/s of memory bandwidth, 50% more than M3 Ultra. M6 is Apple's first 2 nm chip and supports up to 32 GB of memory at up to 170 GB/s. Apple says M5 Ultra can run language models with hundreds of billions of parameters entirely on the device.

## Why it matters locally

On Macs, generation speed tracks memory bandwidth, so M5 Ultra keeps M3 Ultra's 512 GB ceiling while our bandwidth-based estimate puts it nearly 50% faster on the same model.
