If i manually OC, im hitting 14k points in CB but Corona goes down only 1-2s and i have no idea why.

I tried 3.8 max (air) and i went down from 43s to 41. You can see 2990wx hitting 36s at 3.6ghz in the benchmar results.

So im not sure if we can see such a good times with new TR.

Im not getting any proper improvements , not even with PBO. Corona doesnt react to overclock as much as i would like to and i have no idea why. I was able to hit 3200 on the memory as well but again, zero improvements. I think best run was 39s but that happened only once and i wasnt able to reproduce this time again.

Just 2k points less in CB compared to 2990wx. Thats ...impressive.

43 vs 57s in corona. 3970 might be able to hit 30s territory hmm.

Depends on your mobo (MEG / Aorus / Zenith ?? ) , i would check ram kits which were tested and approved by manufacturer.

Regarding speed and timings, if you are planning to run it stock, get 2933/cl14. Thats the best you can get. If you are on budget, go with C15-C16 but not higher.

Depends on the price drop on 2990wx, new 24core might be amazing choice. Just wait for benchmarks. New platform supports 3200mhz as well and you can upgrade later to more powerful CPU. But that means you need to pay for better, more expensive mobo.

Actually i wanted to quote Dfenton ^^


Does anyone know what this could be? As it stands, this system (purchased specifically for rendering animations) is currently slower than my older i9. I'm in a bit of a bind here with a large deadline looming.

Thanks so much for any help!

Are you talking about GI precomp or overall performance while comparing to i9 ?  You probably know it but animation UHD cache takes longer to calculate compared to normal "still image" cache. Maybe you was using normal uhd cache on i9 and comparing it to animation cache ?

I just tested some of my scenes and indeed, while precomputing GI, cpu utilization is around 41-46%.

EDIT : on Intel machine, 100% while precomputing GI. Weird.

Interesting. Since GI always take seconds, I never paid attention to it, but now I am curious so I'll try to benchmark it as well.

Could it be the memory controller for only half the cores ? The Numa? What is your energy profile in Windows?

Good to see you got HyperX stable for 3000 CL15, I tried that same kit on both Alpha and MEG and couldn't, it would always crash. It's on 2800 I think :- (

I had performance issues running 3000mhz on the Aorus. Its default XMP profile for the kit i own so i had to change it to 2933 and difference was noticable.
It was like 10 500pt vs 11 400pt+ (stock). Afaik, 2990wx supports 2933. Everything above needs some fine tuning.

EDIT : Score with 3000 https://i.gyazo.com/4098c922680aeb71712958dd934560fb.png

25s was my "i will upgrade if that happens" estimate. 40% percent improvement in corona would be something im willing to pay for but only god knows what we can expect. Ignoring clock difference and looking just at promised 15% ipc improvement...

What im also curious about is how new TR operates. 2990wx base clock is 3.0 but its operating at 3.2-3.4ghz under load. Maybe we can expect 3970x floating between 3.7-4.0 ? That would def improve a lot of single core tasks.

Yea i was expecting new 24c to to be +- same as 2990wx but considering 15% ipc boost and 800mhz higher base clock, 13-14k points is quite possible. Its like 2990wx in PBO mode. 3970x might be hitting around 16-17k points as you mentioned.

I dont care about anything just Corona atm so thats deciding factor for me. Its just amazing how AMD made 2990wx look like a bit better consumer grade cpu just in 1 year. Overclocked 3950x might score same as 2990wx in Cinebench. Only downside is quad channel and PCIe lanes but honestly, thats not something we are benefiting from (archviz/cpu rendering). From technical POV, 2990wx will remain as 3rd most powerful cpu on the market but from budget perspective, its not that great choice anymore (numa , memory etc).

If 3970x can crunch Corona benchmark in 25s and less , i might be interested in upgrading my rigs but im very skeptical. Not sure if new i/o architecture can help but cosidering that Cinebnech goes up to 13k points after turning PBO on (11 300pt stock) while Corona benchmark does nothing...

Also what do you guys think about higher base clock vs 3ds max ? Running IR while opening HDRis / material editor is quite sluggish for me compared to 4.5ghz intel i had before. This is what drives me nuts the most. I hope there will be some improvement with new i/o architecture in this regard and i dont think 4.5 turbo boost will change anything compared to 2990wx turbo.

I think i`ll wait a bit more for 48c/64c . I dont see any logical reason for me to upgrade from 2990wx. At least not for that price vs speed improvement. Its more about the pcie4 and all the features coming with the new boards (which are hard to fully utilize in archviz anyway).

Im also curious about cooling. Stock 250W in the summer on the air is hard to keep under 65C so i guess 280W will need some custom water loop which is pushnig price even higher.

Im not posting here that much but this is beautiful. Crisp and clean. Metal plating above the chairs on 3rd image is really nice detail.

What HDR was used for dusk shots if i can ask ?

Haha yea.

Now imagine new 32core TR with 17-18k cinebench points. With 10-15% ipc on desktop variants, i`d expect different score but who knows.

https://www.reddit.com/r/Amd/comments/c01sln/according_to_amd_a_stock_3900x_beats_an_all_core/

If stock 3950x can do 9k points, i can sell my 2990wx and just slightly OC that 16core.

Depends how it perform with Corona...

Yea Corona benchmark is not even affected by PBO. Rendertime is still the same with or without it enabled.

And regarding TR, even if they released 64C TR my guess is that it will be attacking 4k+ euro. I dont think we will see 64c TR anyway. There is several logical reasons for it.

There was a lot of rumors about new Ryzens as well and most of those rumors were false.

Absolutely. Any vendor who wouldn't would be massive fool. Look at what happened to prices of 1950X. Yes some shops always keeps their prices up for years, but everyone who actually wanted to sell that CPU did so with up to 60perc. discount. The CPU went for peanuts on bazaars/auctions.

The hype is so strong ! New benchmarks every day. It's crazy that it might obliterate my 18core i9 7980XE (with dellid!!).

Whats your CBR20 score with that cpu ? I was interested in it before buying 2990wx (TR wasnt released yet) after talking with Jakub Cech but im glad i waited for 32c.

Its also sad that in CB R20 i can get almost 12 500 points with PBO enabled but in Corona its always 41s.

In C15 with PBO enabled im getting around 5500 points. Thats 31% difference (just with PBO) compared to new 16c unit. And that should be selling point if someone is deciding between new 16c vs 32c. Overclocked 2990wx can climb even higher.

Question is...it is worth ? Price difference is quite big (if TR prices remains the same).

I`d still get 2990wx but we will see. I hope next gen TR will be compatibile with x399.
