From a quick read, in case anyone is wondering, this is built on the latest-gen 10nm process which is a refinement on the previous 10nm process. Intel's goal was to focus on clock increases, so the instruction per clock is apparently not much changed. From looking at the tables, the whole line of processors appear to have nicely improved one core max clock speeds, which should hopefully help single core performance,…
There's only 15-20% IPC increase from Ivy Bridge (which a 2012 Macbook Pro would've used) to Skylake, there's a similar increase once again to Ice Lake but the clock has actually dropped from 2.5 to 2.0 at least on the 13" side (at least that's what everymac tells me). It is only the core count that shows an increase and their use case might not be more than two cores.
