Apple at WWDC surprised us with the M2 Ultra chip, which is the key feature in the new second-generation Mac Studio. We thought we'd compare it to the first-generation Mac Studio with M1 Ultra chip to see whether it's worth upgrading. Subscribe to the MacRumors YouTube channel for more videos. Compared to the base M1 Ultra, the base M2 Ultra has a 24-core CPU (up from 20 cores) and a 60-core GPU (up from 48 cores). It has the same 64GB unified memory and 32-core Neural Engine.
