People need to look past the ugly RGB lighting and understand the point: What Intel and Apple are calling "professional" performance is now mainstream with AMD.
Did you notice that the CPU used in that build has just 2 memory channels, and tops out at 128GiB, with a max 47GiB/s memory bandwidth ? Or that it has only 20 lanes of PCI?
For reference, the 12 core Xeon Apple will use has 6 memory channels (3x as many), tops out at 1TiB (8x as much) with a max 131GiB/s memory bandwidth (3x as fast), and 64 lanes of PCI (more than 3x as many).
So that machine, is not comparable, at all. Even if you ignore the PCI lanes and memory speed, it supports less memory than a 2017 model iMac Pro, so to suggest it's appropriate/better than a 2019 Mac Pro shows exactly who that stupid PC is aimed at: people who want a tower but don't have *any* use for the actual features a Mac Pro has. That's fine, you can want that, you can even go build that - but that doesn't make it "better" than a Mac Pro.
Just for kicks I went and looked to see at what point the AMD processors a select group are circling up around like a game of soggy sayo actually start to match the Xeons in terms of memory channels, memory speed, PCI lanes, etc. (A million cores won't help you if you can't get data to them quickly enough to keep them busy).
So the first Ryzen 9 with 64 lanes of PCI is the 3960X, with 24 cores.. It supports half the memory of the 24 core Xeon (1TiB vs 2TiB), has 4 rather than 6 memory channels.
Which one is better for a given task will depend on the demands of that task. My point is that all this foaming at the mouth about core counts from AMD processors ignores the other aspects where they're still worse than the Xeon offering.
The only released AMD processors that are close to/match the Xeon in terms of PCI lanes are the two "High End Desktop" models, which both support fewer memory channels than any of the Xeon's Apple will be using, and are limited to the same memory capacity as the base model 8-core Xeon Apple will use.
So based on all this, I have to ask, what is the expectation of all you who circled up around AMD to show your appreciation?
Would you really prefer a Mac Pro with only two processor options, with significantly slower memory bandwidth and half the memory capacity? Just so you can say "ooh looky 32 cores"?
I thought after the ridiculous inflated MHz ******** at the beginning of the century people had learned that a single higher number doesn't necessarily mean the whole thing is "faster" or performs a given task "better".
