The real disconnect there is that this Mac Pro, like EVERY Mac Pro before it, isn’t what most consumers actually want to buy. What we actually want is a well-built mid-tower PC with a ton of ports and PCI-e expansion slots, running standard consumer CPUs like AMD Ryzen or Intel core, priced at a reasonable 35% premium over Dell and HP.
That’s the xMac. But Apple doesn’t want to make it.
That said, it’s 2019 now. Laptops are fast as balls for everything but gaming. If you want to game you aren’t running MacOS anyway, and if you’re just gonna gosh-dark insist, you can get an eGPU box for a $300 premium.
