First, im getting 41s with stock 2990wx, not sure how they got 44s but i was expecting sub 30s for new 32c.

Agree with that, look at the render time, this is a video from 2018!!!!  Time is 41, what changed?!!!

Don't stress the seconds my dudes, I've seen plenty of benchmarks with numbers like 31seconds (and also 41 for 2990WX).

Ondra also plans to rework the benchmark for newer core and hopefully linear scaling like the command line version that shows Rays/s instead.
But yes, maybe due to memory latency, Corona doesn't benefit to same ultra-impressive scaling like Vray. Still...highly impressive.

I quickly bought 3950X on local shop (Alza), 15 minutes later, sold out :- ). Will build it during the weekend.

For the TRX40, Zenith II costs 800 Euro here... and Aorus 1000 Euro. That's rather high. Also the temps are high so you might as well build dem loops :- ).

Smoothness of Max, my 4.4Ghz (constant with idle downclocking) i9 with Quadro RTX 5000 is not exactly "smooth" on 2016. I have yet to test newer versions, but by now I would place blame squarely on Max.

Prices on amazon now
MSI Creator TRX40       700$
MSI TRX40 PRO 10G     500
Asus Prime TRX40-PRO 450$

Interesting what price will be for TRX40 Zenith II in the US,  800 euro is too much high.

Well, average for most of the 2990wx is in 41-43s (stock). In such a small time frame, even 3s is few % difference in performance. 41vs34s looks better than vs 44s vs 34s. Visually and mathematically. I have read other benchmarks as well and i have seen 40s for 2990wx and 29s for 3970x. Not sure whats going on. I never achieved anything under 41s without overclocking manually. Not even with PBO.

For the TRX40, Zenith II costs 800 Euro here... and Aorus 1000 Euro. That's rather high. Also the temps are high so you might as well build dem loops :- ).

Thats good point. 82C on air under load (hey, its winter time) sounds a bit scary. Imagine having your PC running for days during hot summer day without custom loop.

Smoothness of Max, my 4.4Ghz (constant with idle downclocking) i9 with Quadro RTX 5000 is not exactly "smooth" on 2016. I have yet to test newer versions, but by now I would place blame squarely on Max.

Thanks for info. Can you tell me if UI is more snappy with your intel compared to 2990wx  ? What about IR or material creation during IR ?

Anyway, whats your opinion guys on 3970x ? Purely as Corona user i dont think having image done in 100min instead of 120min is worth that money. Maybe for someone doing a lot of animations.

EDIT : New chipset driver for x399 and RM is out.

I can get 2 second variation just by clicking the corona benchmark run after run. The benchmark itself starts bit dubiously, then it could be the initial turbo clocks which are often maintained bit higher just for 5-10 seconds.
The Rays/Second is really much better metric.

I've never found personally all those discrepancies in performance caused by 2990WX, but it's true I never compared it a lot, 2990WX is Veronika's PC not mine. Maybe I should look closer at this but I plan to renegate it to render-farm.

I personally find 3970X great as package due to both having great single-core performance now while still increasing multi-core. So there is no compromise being done now compared to 2990WX.
But if you have 2990WX, I wouldn't necessarily upgrade to this, I would go one step at least higher to make it worth the money the whole platform costs, if there is 48core. If not, then the 64.

Re: Prices of TRX40 boards, the new "mid-range" lol, 500 +/- Euros, seems to only have good enough VRM for the 32-core version, while the mammoth Zenith II/MSI Creator/Aorus Extreme, 800-1000 Euro beefed up enough to run even the 64 core.
I really don't find this market segmentation sympathetic from board brands, 500 Euros gave us 19 phases last year, it can't give it to us now suddenly?

Esp. Gigabyte created fantastic TRX40 and X570 boards only at the very top, and imho intentionally made all the rest worse. At least Asus "mid-range" is good enough.

So it seems there might be a 64 core part in the works for next year as well. Surprise! :)

https://videocardz.com/newz/amd-to-launch-ryzen-threadripper-3990x-with-64-cores-in-2020

@JoeVallard
I respect Linus for standing up to what he believes is right there. He did it in a very negative but still tasteful manner imho.

I'm torn between waiting for the 64 core part or getting the new 32 core now. Things seem to be scaling pretty linearly with the new 32 core in the blurred benchmark image above...however the 64 core may not scale as well as I doubt they will be able to sustain as high all-core boost clocks even with an over the top water cooling setup. I can see the CPU easily drawing 700w+ past 3.5ghz all core (if it's even possible to boost that high). So the 32 core might end up being the best bang for your buck?

I tend to agree. I'm being super speculative here but I think the 64 core version will probably land somewhere between 19-24s which is not exactly 2x of the 32 core version but also not that far off. The lower clocks are imho going to be the main reason for that as the cores have doubled + the TDP stayed the same.

Still, those are going to probably be highly binned chips so some extra headroom will probably come from there as well.

My main question mark with the 64core version is not the CPU itself but Windows. Not sure how Windows will handle 128 threads as its supposed to be sucky in ways unimaginable for even 64+ threads :)

As for the overall release, AMD really outdid themselves with this one. Minus 9980xe (the new one) I don't see a chip that could favorably compete with anything AMD has. The only reason I see someone would take the 9980xe is for PCI-E lanes as it fits nicely between the speedy 3950x (non HEDT) and the super speedy 3960x (HEDT lanes and all). Even then though, I think the 3960x is well worth the money as you get a lot more speed, a newer platform (plus compatibility with future Zens), PCI-E 4.0 and even more lanes.

Really, good job AMD, I'm totally onboard with what they are doing :)

AMD's TDP doesn't say much, there is big difference in power consumption and temperature between 3960X & 3970X.

AMD doesn's list PPT which correlates better.

I would not be surprised by 3990X eating 400W during boost without even PBO turned on.

I'd be happy to see it going to 400W, don't have a problem with that if the firepower is equivalently high :P

Over at Anandtech they seem to think (based on the math that a single die eats up to 6W on current TRs) that we are looking at mid to low 3ghz all core boost and a high 2 ghz base clock for the 64 core part. Speculation at this point but I think it does make some sense given the Wattage restrictions (TDP or otherwise) and the math they are doing.

Epyc 7H12 is the only 280W 64-core chip with base clock of 2.6 GHz. With the process improvements, I don't see why the 3990WX would do worse than that.

I'd be delighted if that happens. Lately I quite value the higher all core clocks :)

Just sharing my latest benchmark finding. Can't wait to see 3990x/wx there. Scary stuff.
Btw 3970x is currently just a little bit more expensive than 2990wx and it's still super fresh.

From the handful of benchmarks i've seen with tech reviews even the 3960x is benching higher than the 2990wx. I don't know the technical side of things but the gains in Vray/Blender/Cinebench are much larger from 3rd gen Threeadripper than what they are for Corona. Could it be that the benchmark is still running on version 1.3?

anyone has any idea when 3960x will be on US amazon?

Amazon seems to be slow on zen 2 release and even when they finally do come up they sell out so fast. By the time I got the newegg notification they were available, they were already sold out for all 3 cpus that came out.

Don't forget to add  +- 450 USD to 3970X and 3960X prices, that's how it works in Europe :)

3960X looks like a reasonable compromise between more expensive 3970X and 2990WX. Maybe it's the way to go, what do you think?

Juraj has found 2990WX for less tan 1000 Euro as far I remember, but I could't get anything even closer to that deal. 2990WX is still way too expensive IMHO, 3960X is cheaper at the moment.
