Description
Apple is replacing Intel CPUs in all machines with ARM cpus. Already have Mac laptop and Mac Mini models with ARM (Apple M1) cpu since late 2020. Apple M1 CPU is 5 nm process vs 10 nm for latest Intel cpus so much more energy efficient, or higher performance at comparable energy.
Macs use Rosetta 2 to run Intel apps on ARM cpu machines. This seems to be working fine for ChimeraX. Native ARM ChimeraX may give higher performance. Python is reported to run up to 3 times faster on ARM cpu vs Intel emulation on Mac.
