The Mac Studio launch during Apple’s ‘Peek Performance’ event suggests that the 2022 Mac Pro unveiling is still on the cards, and we can expect something more powerful than the M1 Ultra as part of its innards. The first evidence of a powerful silicon was spotted online, revealing that the upcoming workstation could use two of these M1 Ultra chipsets to form a single but exceptionally powerful solution.

On Twitter, Majin Bu has posted an image showing that there will be a bridge that helps to connect two M1 Ultra chipsets to form a single custom Apple Silicon. As for what it will officially be called, we have yet to stumble upon those details, though he does mention the codename of the unnamed chipset as Redfern. During its ‘Peek Performance,’ Apple demonstrated that it employed a process called UltraFusion to create the M1 Ultra.
