Apple plans to introduce a new Mac Studio desktop powered by the M5 Ultra chip at its Worldwide Developers Conference on June 9, 2025. Designed for professional workloads, the new Mac Studio features a substantially increased number of processing cores and up to 512GB of unified memory compared to its predecessors. Supply chain constraints may delay the actual release of the hardware until October 2026.
New desktop features massive memory upgrade and advanced chip packaging technology
The new Mac Studio will feature Apple's M5 Ultra processor built on TSMC's N3P manufacturing node. This chip utilizes SoIC-mH packaging technology to integrate multiple silicon dies through bumpless hybrid bonding. The design allows Apple to package the CPU and GPU separately for independent scaling of processing clusters.
Rumored specifications indicate the M5 Ultra will include a 36-core CPU and an 84-core GPU. The system supports up to 512GB of unified memory with interconnect bandwidth exceeding 1000GB/s. These figures represent expected configurations based on current industry reports.
The SoIC-mH architecture enables the separation of CPU clusters and GPU dies within a single package. The adoption of SoIC-mH packaging technology allows for independent scaling of CPU clusters and GPU dies, which is expected to enhance overall system density and efficiency. Institutional investors note that this packaging method supports flexible scaling for different performance tiers.
Apple expects to announce the Mac Studio with M5 Ultra at WWDC on June 9, 2025. Supply chain limitations currently threaten a potential delay of the product launch until October 2026. The final specifications and release timeline remain subject to change based on manufacturing progress.
