The profit margins on Macs must be insane because it just doesn’t make sense at all Apple just doesn’t give a fuck about data center workloads when they have some of the best ARM CPUs and whole packages on the market.
If Xserve is any basis of comparison, Apple struggles to sell datacenter hardware in the best of markets. The competition is too hot nowadays, and Apple likely knows the investment wouldn't be worth it. ARM CPUs are available from Ampere and Nvidia now, Apple Silicon would have to differentiate itself more than it does on mobile. After a certain point, it probably does come down to the size of the margins on consumer hardware.
I will never not be forever saddened by the fact that Apple killed their Xserve line shortly before the App store got big. We all ended up having to do dumb things like rack-mount Mac Minis for app CI builds for years and it was such a pain.
there was news they recently bought a lot of nvidia gpus since their progress was too slow to use their own chips even in their own data centers for their own purposes
