Apple today announced new Mac Studio models with the M5 Max and M5 Ultra chips, the latter of which is the company's most powerful chip ever.
The new Mac Studio features a next-generation SSD architecture built on PCIe Gen 6 that Apple says is up to twice as fast as before. The machine also gains Thunderbolt 5 ports with up to 120Gb/s of bandwidth, along with Wi-Fi 7 and Bluetooth 6 for the first time via Apple's N1 chip. The new Mac Studio also supports genlock over USB-C and can drive up to eight displays.
The M5 Ultra chip includes an up to 36-core CPU that contains 12 super cores and 24 performance cores. It delivers up to 1.25x higher single-threaded performance and up to 1.3x higher multithreaded performance than the M3 Ultra from the previous generation Mac Studio.
The M5 Ultra features a GPU with up to 80 cores, and a Neural Accelerator is built into each core, offering up to 4.5x the peak GPU compute for AI tasks compared to the M3 Ultra and more than 6x compared to the M1 Ultra. Apple says the GPU's latest shader core technology, paired with second-generation Dynamic Caching, hardware-accelerated mesh shading, and third-generation ray tracing, delivers up to 40% faster graphics performance than the M3 Ultra.
The chip also includes a more capable Media Engine, with dedicated hardware for H.264, HEVC, four ProRes encode and decode engines, and hardware-accelerated AV1 decode, along with a 32-core Neural Engine for on-device AI tasks.
The M5 Ultra is built by connecting two dual-die M5 Max chips using Apple's next-generation UltraFusion technology, which increases inter-die bandwidth to over 4.4TB/s and connection density by more than 6x, allowing the four dies to function as a single processor.
The new Mac Studio with the M5 Ultra supports up to 512GB of unified memory and up to 1.2TB/s of memory bandwidth, which is a 50% increase over M3 Ultra. Apple says the added memory and bandwidth allows users to store large datasets locally, increase tokens per second, and run large language models with hundreds of billions of parameters entirely on device.
Users can also cluster multiple Mac Studio systems together using built-in support for Thunderbolt 5 and RDMA (remote direct memory access), creating a shared memory pool across systems. Apple says a cluster of four Mac Studio systems delivers up to 3x faster AI inference than a single system.
The Mac Studio is also now available with the M5 Max chip, offering an 18-core CPU with 6 super cores and 12 performance cores, up to 40 GPU cores, up to 128GB of unified memory with up to 614GB/s of memory bandwidth, and up to 8TB of storage. Apple says the M5 Max delivers up to 3.9x faster AI performance than the previous generation.
The new Mac Studio will be released on September 22, but the model with 512GB of unified memory launches in late October. It is available for pre-order now.
