Even if Intel were to bring forth hardware mitigations, it'll still slow the chips down. Intel needs a radically new architecture from the ground up for it to leave the attack vector road. It's probably why they hired Keller last year to work on a new architecture for them. If the Mac Pro is delayed for that alone, you're looking at 2021-2023 before something new pops up. While the smart decision is to go with Threadripper 3 or whatever, but this is Apple we're talking about. Smart hasn't been around since Steve passed away.
Though for what it's worth, Ryzen in general is ECC capable, but I believe can only do 1 bit error profiling.
The problem with these vector attacks is you wouldn't know if it hit you or not. And we don't know what else lies in Intel's immediate future in the form of bad news concerning attack vectors.
Mozilla has put out some software mitigations for Firefox, Microsoft and Apple did their own part to help. Intel will be releasing microcode updates next month. The big take away is you could have been infected and you wouldn't ever known until months or years down the road when stuff turns up on the web or worse.
For enterprise, small business, big business, and even render farms, these mitigations slow down work but also are required unless you want to willingly put customer data at risk or not be able to check in with authentication servers for whatever software you're running, at least for render farms.
Speaking for myself, as I prefer to build my own workstations and pop into this thread to give my opinion or correct people, I'm very much going back to AMD after having not used them since Athlon64. I don't see why I should pay for anything Intel when I know this won't be the last time we hear about and Intel architecture fault. The 3900X sings to me, but the rumor of a 16 core Ryzen processor is drool worthy.
The fact that Intel knew about some of these architecture faults and still sold chips and tried to bribe researchers leaves a bad taste in my mouth. They haven't ever learned their lessons over the decades.

We switched to PC and are larger than the 1500 headcount you listed. They are the standard in VFX. Sometimes windows, sometimes Linux. There are still a few Macs kicking around in the art department.
Yep. Plus, places like that will likely be using W10 Enterprise or LTSB, which is very far removed from typical Windows 10.
