in my opinion, the 64c is overpriced... 3200$-3400$ would be a great price.

All aboard the hype train :- )!

When did 3970X benchmarks leaked, on their launch day?
No TRX/WRX80 platform though. So I guess it's 4-channels.

for me, 3970 is the best choice, for now, will order tomorrow :)  + this TRX40 AORUS MASTER

Yeah it well could be the best choice due to higher base clock and no processor groups. Let's wait for the benchmarks to see if 3990X is miracle, or has some caveats in overall productivity.

But you have to give it to AMD, they do deliver on CPU front.

25399 cinebench r20 score phew. For double the cores/thread and price of the 3970x, the performance seems like its a bit low (getting about 50%?) Noticed they didn't list the TDP lol

Soooo when you gonna build yours Juraj? hahah

Get the feeling that the 3990x is gonna do the Corona Bench in 18-20 seconds. Not even enough time to stretch it legs!

Bit of an issue even sourcing stuff!

Fast memory kits for TRX40: Impossible to buy anywhere almost.
Aorus Xtreme: Nowhere. Every shop is "on demand".
OptimusPC waterblock: Nowhere, still on pre-order.

They did list the TDP, 280W, but it really doesn't say anything. 3950X has 105W TDP and it eats 150+ Watts. TDP is next to useless metric at this point.

Everything is just starting to come back into stock here in the States at a markup of course. The high end boards and both cpus have been out of stock for awhile now.

3600Mhz 32gb sticks all i'm seeing is a couple Corsair 2x32gb kits (RGB and Non RGB) Not even very many 3200Mhz kits either, I see what you mean.

I'll have to see more tests, maybe there is a issue running 64 cores in windows or cinebench that needs to be worked out. But 25,000 is kinda disappointing especially for $4k. Was hoping double 3970x. That would be around 33,000 score.  Seems you might be better off buying 2 3960s.

I actually think the pricing is kind of a marketing misfire.  Going with $3,990 is too 'cute.'  When you're spending that much money you don't want it to feel like an arbitrary number :)

$2.6k more for a CPU vs having to buy another mobo/cpu/ram/psu/case/cooling/gpu probably run you close to that same 2.6k little less if you go with a bottom end gpu.

The 3970x takes 16 seconds to render R20. High possiblity that the 3990x is finishing the test too fast and giving inaccurate results. The 3990x is more than likely finishing R20 faster than what my 2950x can do R15 in :D

Dual Epyc 7742 (128 cores 256 threads) reaches 30k.

This is single 64core with 85perc. of that performance. It can't scale linearly at this point that would be almost impossible, or lead to absurdities like that 50 000 euro 9289 400W Xeon that you have to specifically order as whole system and apparently almost none were made.

Given that this CPU is water-cooling must basically, you might as well be able to do such thing yourself. At 4k CPU, 800 Euro loop is not exotic investment anymore and nothing holds you from putting the power limit at 500W which should give you that last 10perc. of performance to nicely square of 30K points :- ).

No info on TRX WX80,hmm.. they ditched that completly? No mention of 48core 3980 either..
So 3970X seem like best choice now, or wait one year for 7+nm refresh.

I'm now second guessing whether to get the 64 core due to the anomalies listed above (windows processor groups, low R20 score, no mention of the TRX80 boards).

I guess the low R20 score could be attributed to two things:

1. Low all core boost to keep the stock TDP at 280w - I assume this can be resolved with a touch of overclocking?
2. The benchmark finishing too quickly to give an accurate/scalable result.

Seeing as my main use case will be for Corona, I'm going to wait until I see a nice linear Corona bench score pop up else I think I'll go with the 3970x and upgrade again in 2 years+ when the quirks of a mainstream 64 core CPU have been ironed out - by then we'll also have DDR5...so much to think about.

Also Juraj, I spoke to Optimus and they are aiming to ship out the Threadripper blocks next week.
Vray who?

At the moment I am 50/50 on whether to build 3970X or 3990X. I am trying to have as little as necessary PCs and only the fastest so 3990X as workstation fits the bill (maybe even keep just super-fast workstation + cloud rendering as one smart person advised me :- ).
On other hand, 3970X is package without any hardware or system compromise. It's the ultimate chip (just like Xeon-3175X would be if it had normal power draw when clocked properly).

Heh I just wrote them another email today but didn't get reply yet :- ). I really put a lot of faith into their product because the issue with cooling Zen architecture is not so much thermal dissipation but the transfer away from dies, so the block could really be a game changer.
Or not. Who knows..without any test, it's kind of risky to place 4000 Euro chip under new block that 'could' even potentially leak (through cracking or whatever, they do swear by their use of plastics).

Bit sad there is no TRX80, would have been interesting to see another potential behemoth motherboard like ROG DOMINUS.
