Apple has just introduced the most powerful member of the M1 family, the M1 Ultra chip at the Peek Performance launch event. The new chipset powers the recently announced Mac Studio.
The M1 Ultra features an UltraFusion Architecture that connects the die of two M1 Max chipsets. The architecture uses a silicon interposer that connects the chips across more than 10,000 signals. This provides 2.5TB/s of low latency inter-processor bandwidth.
Thanks to the new architecture, the new chip has a 20-core CPU with 16 high-performance cores and four high-efficiency cores. It allows the chipset to reach peak performance using 100 fewer watts.
Moreover, it has a 64-core GPU that’s 8x the size of the M1 chip. The chip also has a 32-core Neural Engine that runs up to 22 trillion operations per second.
The unified memory architecture has also been scaled up to 800GB/s and the chip can be configured with 128GB of unified memory.
