Once Intel does release this new crop of Xeon-W's that will be inside the new Mac Pro, why don't you go build one and find out if you can do it for half the cost and let us know?
Why would i do that, when i could build
32 core AMD Threadripper, with a couple of terabytes of M.2 SSD, with a pair of more recent GPUs, STILL for less money than what apple are charging for 8 cores and an SSD i wouldn't even consider big enough for my Macbook?
I've had 8 cores, 32 GB of RAM and dual Vega 64 GPUs for around $4k aussie for 18+ months now.
Yes, it isn't a Xeon. It clocks faster. I could have gone Threadripper (with way more than 8 cores) instead and still come in under Apple's budget by a LONG way.
Literally the only reason to even consider the Mac Pro is for the ASIC (which is of limited use) and/or MacOS. Their hardware costs are a joke.
Part of that reason is because Apple somehow refuse to use processors from AMD despite Intel being massively out-classed at the moment. But that's their choice.
Another part is because they seem obsessed with un-necessarily reinventing the wheel with custom fancy looking enclosures that simply do not provide any benefit for performance. Its going to live under a desk - focus on performance per dollar, not fashion, thanks. This is a pro machine.
They could/should have got AMD to get them some highly binned EPYCs - you can get 64 core EPYCs now for WAY less than what intel are charging for 28 cores. AMD are also doing custom processors for plenty of others, they wouldn't even have been limited to what AMD have in their parts bin...
