I agree.
Honestly, I’m interested in a Mac Mini or 16” MBP using ARM. The Mac Mini could probably get a dGPU again in its current power budget. The MBP could probably quiet down for CPU-heavy loads, and be easier to cool when running dGPU loads.
And those would honestly be competitive using A12-derived silicon. Die yields being the risk there as it grows in size to accommodate more cores and more I/O that these computers need compared to the iPad.
It’s just not obvious to me that you can take the A12Z and get something in the 32-core range meant to handle Workstation level loads without a lot of work. Apple has done a lot of good work with the A series, but past performance is never a guarantee of future results in the CPU space.
This is also the same company that released the 2013 Mac Pro and let it rot. In their own words it was because they misjudged the direction of the market. So there’s the optimist in me that agrees with you, but there’s also the skeptic that points in the direction of the Mac Pro’s history over the last 7 years.
As I said, I think it’s fair to be skeptical at this point about the high end. At least until Apple gives us something more substantial than a DTK using existing silicon, and silence about the roadmap.
I think you are missing the point here....the GPU is built in, that is why apple is building its own as it does both functions very well....
