Up to 96 cores and 12 DDR5 memory channels with AMD Zen4-based server processors.

Up to 96 cores and 12 DDR5 memory channels with AMD Zen4-based server processors.

So in the previous post you've read about the recent Gigabyte breach, which exposed source code from Intel and private papers from AMD. And all of a sudden this data is out; AM5 motherboard BIOS and info on ZEN4 server procs have leaked. 

User Yuko Yoshida (Twitter) has shown that the Genoa series consists of 12 chiplets, on Twitter. This totals 96 cores and 192 threads, all running at the same time. The number of cores has increased, while the number of memory channels has increased by 1.5 times (from 8 to 12).

Zen 4-based server CPU will be the first to support the avx-512 instruction set. The SP5 socket has 6,069 contact pins to accommodate all of this computing power and extra features. Other documents state that the energy consumption goes up, even if the standard and configurable tdp is not indicated ( 320 and 400 watts according to speculations). The value of this quantity is held for a maximum of 1 ms, whereas up to 440 W (one horsepower) of power can be applied for a duration of 10 ms.

At the end of October last year, AMD CEO Lisa Su revealed that the company's Zen 4 processors and RDNA 3 graphics cards are both on schedule, with devices including these architectures set to launch within the next several years. TSMC's 5nm technology is expected to be used for both of them.

I'm going to for a moment ignore that your argument is personal anecdotes, because obviously there are exceptions.
Are you talking about render farms or workstations? Because yeah, if you're actually editing videos or compiling code, TR is the way to go; that's what it's built for. If you're talking about servers and...:
A. ... if there are a lot of servers (like multiple racks), either they're handling a very specific workload that doesn't benefit from any of Epyc's advantages (totally possible), or they're being irresponsible by ignoring why Epyc is different.
B. ... if it's only one rack or just a couple towers, that only further emphasizes my point: even now, AMD doesn't really have any sensible entry-level server options. If you're on a tight budget, I could see people resorting to TR because it's the best bang-for-buck. That's not the norm though.

That sounds like workstation to me.
TRs with over 32 cores are a poor choice for VMs due to the significant RAM limitation. 32 and under, it's a great choice.

EDIT:
Also... none of these places use Intel? I know Intel isn't a great value for high-end stuff but still... none of them?

not in creative.
time equals money the money spent upgrading to AMD is far less than the money saved. if you're doing a film/tv show/ animation the time encoding on Intel (at higher cost of ownership and operation) is days vs. hours on AMD which costs less and is more efficient. and you're talking enough workstations to make electricity a cost concern and heat an infrastructure issue that costs more too.
i'm well familiar with one production company (skydance) in Santa Monica and the editing suite is a thing of (TR) wonder... then they have the animators, artists, set designers, etc... all running TR.
only the studios have server farms (Epyc) for distribution, including streaming to theaters AND services
Google is much the same, but with a greater number of legacy servers

Yes I understand all that, but you're acting like these systems are upgraded to the latest and greatest whenever possible. Though I can see TR being fast and cost effective enough to encourage most studios to upgrade around the same time, you have to consider ROI. Some studios might have an older system that still hasn't yet paid itself off to warrant replacing yet. So it just seems pretty fishy that ALL studios have upgraded to TR.

What was the point of you "disagreeing" with me then? You basically just told me the workstations use TR (which is what it's supposed to be used for) and Epyc for servers. None of that contradicts anything I've been saying. It's like you're arguing for the sake of arguing.
