Yesterday briefly an iMac 27 with Ryzen 3950 CPU appear at geekbench then removed, consider it maybe an Hackintoshs, or an prototype, looking for captures bringing more details to discard an Hackintosh.

If Ryzen was actually coming to macs we'd know already from device ID/strings in macOS betas that 9to5mac regularly leaks, right?

Yeah, back to RISC (OK, don't come again with x64 being RISC...).
They must have some high power ARM CPU testing in their labs I guess, nothing new here.
But there's a problem: the naming scheme :)
A series is taken by the mobile SoCs. Wx (for workstation) is also taken, so is Sx (server?), as well as Hx (for High Power) and also Ux (for Ultra High Power?) :)
You see, ARM is not an option, no naming available that suits it.
Too bad

i'm all for ARM, the sooner the better.
The CPUs in my office iMac 2015s have been running 24 hours per day, every day of the year with heavy video editing workloads - with very few days down (tsunami related events mainly) since the first day they entered the office... with no issues. I haven't seen any information that ARM chips can hold up under that type of use. Can they?

ARM doesn't make CPUs, so it's not possible to answer your question in general.

Different companies license the ARM architectural designs, tweak them, and contract silicon fabs like TSMC to produce CPUs.

Thanks for the clarification. Do you think the threadripper can handle the workload I described.

Both, as for Threadripper it's just an Rebadged Epyc Server CPU, and about ARM, yes it can as long you source it right, at the moment the best ARM sever CPU is made by Marvel (not Marvell) the ThunderX3 but not widely available, neither you can build a diy desktop or servers with that chip it's for OEM/Server Farms.

Threadripper is NOT a rebadged Epyc.

Threadripper has quad channel memory (256Gb max) and runs at a higher clock speed.

Epyc has 8 channel memory (2Tb max) and a LOT more pcie lanes.

And do the chiplets share the architecture?
Basically both CPU complex share the core chiplets, it's hub it's tailored to the L3 cache and I/O buses by it's SKU, this hub is made with 10nm process and it's different for Threadripper and Epyc mostly about memory I/o buses and pcie.

This hub is the one likely to get customized by or for Apple in an hypothetical Ryzen Mac.

And do the chiplets share the architecture?
Chiplets are the same for every, single chip: from Dekstop Ryzens, through Threadrippers, to EPYC CPUs.

What differs are I/O dies, and feature sets in them. Threadripper and EPYC have absolutely the same I/O dies(for manufacturing scale reasons), but with features disabled on Threadripper dies.

In essence, Threadripper 3000 series is an effect of product segmentation.
