Apple has unveiled another M1 chip, the M1 Ultra, which Apple claims can outperform the M1 Max without sacrificing power efficiency.

The new M1 Ultra, announced during Apple's March 8 keynote, is essentially two M1 Max chips combined into one. Apple claims this approach, called UltraFusion, enables a new M1 chip that can deliver up to 2.5TB of bandwidth between the two processors with low latency and without much power consumption.
If we look at the M1 Ultra as a single processor, Apple says it can handle up to 800GB per second of memory bandwidth and support up to 128GB of unified memory. It also packs a 20-core CPU and a 64-core GPU, making it eight times faster than the original M1 chip and double the performance of the Media Engine compared to the M1 Max.
Compared to desktop PCs, Apple claims the M1 Ultra can deliver up to 90 percent higher performance than the fastest 16-core system in the same power category. And in terms of power, Apple says the new chip can do this while using 100 watts less than those 16-core systems.
