Apple
today announced the M1 Ultra chip, the third iteration to the M1 family, and it represents the next "breakthrough" for Apple Silicon.
M1 Ultra consists of two M1 Max chips connected with die-to-die technology called "UltraFusion." The new highest-end chip of Apple Silicon features 114 billion transistors, with higher support for bandwidth memory at 800GB/s.
UltraFusion allows two M1 Max chips to connect together across more than 10,000 signals, offering 2.5TB/s of bandwidth, according to Apple.
M1 Ultra has a 20-core CPU, with 16 high-performance and four high-efficiency cores. M1 Ultra supports up to 128GB of unified memory, an increase from the up to 64GB memory supported by the M1 Pro and M1 Max.
In graphics, M1 Ultra has a 64-core GPU, which offers 8x faster graphics than M1. M1 Ultra has a 32-core Neural Engine, which can operate 22 trillion operations per second and has two separate media engines.
As is common with Apple Silicon, Apple claims that M1 Ultra offers "unprecedented" power efficiency with equally unprecedented power.
The first Mac to feature the M1 Ultra is the Mac Studio, which is aimed at creative professionals. The Mac Studio is
available for order today.
