@arqrenderz - search on ebay ES and you will find it.

@Radim Razzak - search on the supermicro site for your country maybe you can find a local re-seller in your country that might be cheaper then ebay or amazon and you have actual warrenty from a local place plus a possibility to get ram from them as well. I searched for the boards on ebay and amazon first the only available in Europe was in London and it costed 750 pounds without shipping not to mention the taxes my country would make me pay if I order. Finally found local re-seller on supermicro website and it costed 530 euros...

I actually have an X299 Taichi XE which is 12 phases I guess. Bought it since I thought I could push the 14 core I9 harder but I just hit a wall at 4.2 Ghz all core on a Kraken X62 and thats it. I won't even start on the topic of some cores (2 best cores) being from 9-11 degrees C cooler then the last 2 which are the worst... I guess deliding the chip and a fency waterloop of at least 400 euros would make it perform better but is there any point to invest in this now that TR 2 is out and that for the same money you can get the upcoming 24 core which is surely faster then then any of the delided I9's I guess even then the 18core XE which delided and waterlooped will cost you more for sure...

When I got the 24cores they were 500usd on Ebay with included shipping while the 28cores were 1000$ and not a good buy but now they are 800usd and I guess they scale the same way as the 24cores do against the 20core-ones. So for sure are 30% faster then the 24core counterparts and are even a better buy now. For me its not more a habit it has become a fetish of sorts... I have to control myself as well. At least the winters in the office feel like summers nowadays :D.

Yes its actually closer to the 1.5k euro since the 2990wx at least where I buy 90% of my components ( Eastern Europe Hungary ) is like 2080 euros rigt now. It was the same with the 1950x after 3 months from release the price went down and I am sure it will for the 2990wx as well. The 1920x was like 360-380 euros a few days ago and I grabed that one as well but the 1950x is like 25-30% better in actual rendering tests. To be honest I am not that happy with amd since I usually want to overclock everything I buy its like an addiction :). I mean the product is great don’t get me wrong you can’t buy anything that gives you this performance from the blue team for the same amount of money. The thing is that I had this small problems when overkloking on asus x399 boards. I increase the cpu ratio and the cpu is not responding - stock speed on all core values when I test it... As soon as I update the bios voila it works but when I hit the limit and reset again not responding and I have to go back and forth with bios flashing... Intel on the other hand, the I9’s, they don’t have this kind of overkloking/bios problems they “just” overheat like crazy and cost 30% more... Also for some reason amd tends to give better CB scores ( 1950x vs 7940x  ) yet the i9 performs better in Corona bench and real-life rendering situations.

Back to the Platinum vs 2990wx as render node story. So aside from the initial 1.5k saving I guess you will also save alot on electricity in the long run. I haven’t had time to check how much power it pulls directly from the wall when its rendering but I will check it today. The cpu’s are also crazy cool when rendering they are at max 45-48 C with the new Noctua lga 3647 14s coolers. And from what I seen the 2990wx has a Corona bench score of 36 sec ( the best result with it on the list ) I actually got 31 sec with the 24c Platinum a few days ago. I attached a photo of a 10 minute rendering. Titan 4 is the dual 2698v4 es cpu with 80 threads I got around 1.5 years ago, Titan 5 is the Platinum 24 core. You can see that after 10min 2698 has 40 passes while Platinum 8160 has 74 even though the difference in CB points is 750-800 and Corona bench is 48-47 vs 31-32. Just another proof that the fast benchmarks are not a real measurement of power...

@Radim

Sorry for hijacking your thread with this post :) I went kinda off-topic.

@Juraj

To be honest I always hated ecc compatibility it even costed me double sometimes... Stupid me for not blindly following the QWL list and trying to save a few bucks with ram that has just one different letter code then the one on the qwl... But to be honest I also had problems with Threadripper ram as well but at least it worked, not at the desired clock speeds but it worked. As for the ram I got for the Platinums it was relativley cheap around 170$ for a stick of 16gigs brand new from Supermicro reseller were I also got the X11 dph-i board. Just told em what board I want and they said they will make sure it will be compatible or they will change it on their expense.

I was actually going for a node this time. Already have a few workstations around like the i9s and the 1950x and 1920x. Will probably make a 2990wx but ill wait a couple of months when all is sattled, coolers, mobos, etc... Its actually more then 1k difference at least with the prices I can get around me here in my country. But yea the 2990wx is just another beast and generally like 99% of my rendering time during the day is interactive rendering not distribute, which is done like once or maybe twice at the end of the day. So makes sense to take the fastest possible machine for a workstation.

Hi you didn’t write for what kind of work you need it. Will this be a workstation pc or a render node? Since you mentioned Ebay I guess you are not shy to get an ES or QS cpu? Anyway a good second hand v3 xeon for a workstation would be the 2683v3, 2686v3 or a 2696v3 ofc all QS samples since ES are only good for render nodes and nothing else. But to be honest at this moment a good workstation cpu that is the best bang for the buck and yet a good performer is not a xeon, but any of the ryzen threadripper chips. Especially the last gen-ones that are really cheap now.

If on the other hand you need it for a render node then Xeons are better since they are cheaper to build and burn less electricity. A good cpu would be a 2698 v4 ES. Gives you around 4200-4400 CB points and a 46-49 sec Corona bench score. Although I would go for the 24 core Platinums now they are really I mean really cheap and give you better then 2990wx performance for half the money (31-33 sec of Corona bench score) but thats another socket... You can always buy an X11 mobo though :).

Anyone got some tips on whta cooler to use for this socket for 24c Dual Intel Xeon Platinum 8160? I found this one >SUPERMICRO 2U Active CPU Heat Sink Socket v2 LGA3647-0 but not sure if it can keep up with the CPU?

Here is a link of the cooler:
https://ipon.hu/shop/termek/supermicro-2u-active-cpu-heat-sink-socket-v2-lga36470/1665364

*EDIT

Actually found that Noctua released their new LGA3647 coolers so they are already available for purchase. Has anyone tried them yet?

Thnx for the quick answer Juraj. No qs is v3 while oem is v2. Seems that vray ignores AVX instrucions and works at same clock speeds as CB.

Just tested 2 other Xeons that are oem and qs. Oem works exactly at same frequency in both CB and Corona benchmark. QS is overclocked about 100 mhz and only shows in CB while in Corona is 100mhz less. Apparently the biggest hit is taken by ES cpu's. Don't know how its not a negative thing since it is 400mhz less per core on 20 cores so its also slower rendering time. Thnx for the answer Juraj but I dindn't really understand if this can be bypassed in bios or not?

Just tried Corona benchmark with 2698v4 es Xeon cpu. I'am guessing this is AVX issues since in Cinebench all cores are running on 2.3 ghz while in Corona benchmark they run on 1.9 ghz? Also tried in distribute rendering in a standard scene not Corona benchmark same problem. Is this issue fixable? Motherboard is Asus z10pe-d8 ws. Haven't tried to play with bios.
