8 PCIe slots, 4 of them double wide, 64 PCIe lanes, 1.4 KW power supply, just need to figure out how to install Ubuntu on it :)

Lol, what a joke, a 15k+ desktop based on 8180 Platinum weaker than under 5k 2990x Zen based machine.

The new zen machines will have PCIe 4 communication.
July 7th, I think, for up to 16 cores. A bit more wait for something beefy.
We know that there will be a new threadripper, but timing for that one is shrouded in mystery

7/7 only Ryzen's. 3rd gen Zen's not before Q1 2020.

Yea, the CPU is lame compared to AMDs Threadripper/Epyc, and it is pricey,
and it is even unknown if the new Mac OS will have Cuda and OpenCL...
but hey, it's an Apple ;-)

Yea, AMD has currently the forehand, but Intel will switch 2020 or 2021 to 10nm
production i guess, so Apple will surely do an refresh of the system...

Hmm, Apple ships them with an 2*2 AMD Radeon Pro Vega II GPU option,
up to 16384 cores, 128 GB HBM, 56.4 TFLOPs fp32, 112.8 TFLOPs fp16 in sum,
so the new Mac Pro competes with Nvidia's DGX-1 Station with 4 Voltas,
and these are pricey, 37K to 52K Euros...

so the question is, which dude will tune LC0 for Apple's AMD Vega II GPU :)

Considering that dot product in OpenCL is at least 10x slower than in cuDNN, probably no one.

You can check LC0 benchmarks using cuDNN and NVIDIA RTX cards and using openCL and AMD RX Vega cards.
