The Apple M2 Ultra gets 24 CPU cores and up to 192GB of shared memory

Apple has kicked off its developer conference WWDC 2023 and a new processor was introduced on it Apple M2 Ultra. This innovation connects two M2 Max chips using the ultra-fast UltraFusion bus, which ensures a throughput of 2.5 TB/s. Everything is designed to make the processor appear to the system as a single processor, so nothing changes for developers when developing applications. Their apps can run on the M2, M2 Pro, and M2 Max chips as well as the M2 Ultra, even though the latter is a fusion of two processors. The resulting processor has 24 CPU cores, 16 powerful and 8 economical. The M1 Ultra also had 16 powerful cores, but only 4 economical ones. The total number of cores thus increased by 20%. However, since it increased in the area of ​​energy-saving cores, the total performance should increase by less than the 20%. But further modifications of the processor produced by the second generation of the 5nm process at TSMC made it possible to achieve that the CPU performance is just that 20% higher. However, in the case of DaVinci Resolve, there were much larger increases, up to 50%.
