Many of us keep an emergency external drive at the ready by our Mac, in case we need to use it to recover from problems. What’s the equivalent for Apple silicon?
How much faster are P cores at running the same thread as E cores, and how much more energy do they require? And how do they compare with using the GPU?
A look at some of the factors determining the performance of new M3 chips compared to the M1 and M2 versions, and how not to compare them.
