Now I understand why would you think in such way, and I also remember when the first ryzens came out and everyone was shitting themselves, but this is a very special case and I am going to explain it down to the last details why I would still go platinum ES.
First things first, the platinum was always the top of the line, multisocket, most-core variant of the lineup, so yeah, it does have AVX2.
"Crap single core performance" is a bit misleading, isn't it. We are talking about Skylake, not some gunked up Core2duo. So the performance of a core would be pretty much equal if it wasn't a manycore server processor. I don't need to explain this means it's thermally constrained, but keep it in mind, because it will matter.
I don't game. It's not a thing. But if it needs to, these beasts can turbo up to 3.80 Ghz (again, thermals). Summarizing all the cpu specs, Xeon has around 24-28 slower cores compared to the top of the line ryzen 3950x, which has 16 cores, albeit faster and cooler since 7nm lol.
However, moving onto memory, things become a little more interesting and we have to start comparing them as platforms as well. Little known (I didn't know it) that common Ryzens support ECC. Now, if I need that, is an other question, we will go into that in the workloads section, but for now, it's clear that it's a feature both cpus support.
Memory channels. Xeon has 6, SIX, while Ryzen has 2. Then again, the benefits here do really depend on the usecase, and, of course you need to populate the six memory SLUTS to make use of this strong point. The Xeon also supports tons of more memory, a single socket can take on 768GB, although we bump into the very real financial limit posed in the opening post of the thread. I hope these two last features show just how much of a different ballpark the two platforms are and platinum xeons are no joke.
Now, the case for Ryzen, PCIe 4.0. This little thing had my attention earlier in the month while I madly scoured the net for PCIe 4.0 peripherials, but there is not much right now. What already benefits from this is NVME storage, there are some really good offerings at the market right now like the Aorus m.2 drive that has double speed compared to your average samsung evo schtick stick.
