Apple has announced the M2 Ultra chip as part of its WWDC 2023 keynote. The new high-end chip succeeds the current M1 Ultra and joins the M2, M2 Pro, and M2 Max chips as the company’s current generation of Apple silicon.
Like its M1 Ultra predecessor, the M2 Ultra comprises two interconnected M2 Max chips through Apple’s UltraFusion technology. UltraFusion is a silicon interposer connecting two M2 Max chips through 10,000 signals, with a maximum inter-processor bandwidth of 2.5TB/s. This enables the M2 Ultra to pack 134 billion transistors compared to the M1 Ultra’s 114 billion, and a maximum memory bandwidth of 800GB/s
A new 24-core CPU powers the M2 Ultra, spread across 16 high-performance and eight high-efficiency cores. Apple says the new CPU is up to 20% faster than its M1 Ultra predecessor. M2 Ultra can be configured with up to 192GB of unified memory, the highest ever of any Apple silicon chip. This represents a 50% increase over the M1 Ultra’s maximum memory capacity of 128GB.

M2 Ultra offers up to a 76-core GPU, up from its predecessor’s count of 64 cores. The new GPU enables a performance boost of up to 30% compared to the M1 Ultra. In addition, it also boosts a new 32-core Neural Engine capable of 31.6 trillion operations per second, which is 40% faster than the one on the M1 Ultra.
The M2 Ultra chip is available as a higher-end configuration of the refreshed Mac Studio and the new Mac Pro with Apple silicon.
