Apple Silicon M1 Ultra is official: Apple announced it during the Peek Performance event. Basically these are two M1 Max chips connected to each other through a proprietary technology called UltraFusion , which has remained secret in the M1 Max die so far.
Johny Srouji, head of Apple’s chip division, said the company has implemented a feature in the M1 Max that allows two chips to connect to each other but behave as one , thus avoiding potential problems in programming and memory sharing. The link transfers up to 10,000 signals simultaneously and has a bandwidth of 2.5 TB per second.
In other words: M1 Ultra is like putting two M1 Max chips on one card, but without the downsides of a traditional dual processor system. The resulting chip is monstrous from many points of view: first for the size (just see the comparison above), and then for the performance, especially in relation to energy consumption . We list some numbers provided by Apple (unfortunately some terms of comparison are usually difficult to trace):
