Cubase is not compatible with the i9 cpu.
I’m planning on buying a new 16” MBP. They come with the i9 cpu, super fast chip and up to 64 gb ram, 4 times faster than the i7, 16 gb ram.
But unfortunately Cubase / Steinberg products are not programmed to take advantage of that cpu. The same can be said for window machines:
Personally I wouldn’t wait around for Steinberg to get up to date with new technologies. Logic Pro X works with the new MBP i9.
I was in the same situation as you in 2012 I’m not making sacrifices again for Steinberg. Like returning a $3000 MBP Retina only to get another years later.
Maybe it will take Steinberg years to catch up like it did for the MBP Retina.
