Overview
- Macworld discovered references to a t8152 identifier and the codename Hidra in Apple’s internal code, suggesting active testing of an M4 Ultra chip.
- An M4 Ultra would mark the first Mac Pro update since its 2023 M2 Ultra debut and could reestablish a performance gap between the Mac Pro and Mac Studio.
- The M4 Max’s lack of an UltraFusion interconnect implies that an M4 Ultra may rely on a single monolithic die, complicating design and raising production costs.
- Bloomberg’s Mark Gurman has highlighted production challenges and low-volume economics for high-end Macs, indicating that internal testing does not guarantee a commercial launch.
- Analysts extrapolate from the M4 Max that the M4 Ultra could feature a 32-core CPU, an 80-core GPU and start with 96GB of unified memory, though official specs remain unconfirmed.
