Are you pulling assets from nas or over Ethernet? Are you rendering local on all? We can try a sample scene rendered on your be mine too see if there is a difference.

Going to go back to this again as there's something wrong. Recently bought another 64core threadripper 3995wx (used) to complement my existing 3990x and 4 other 3970x machines. It really annoyes me that all 4 3970x machines are way faster than the 64 core machines at rendering!! All latest drivers, os builds, bios, Corona 11 (+hotfix), 3dsmax 2024.2, 10gbe lan, AC on all machines. There is something going on here as we've now tested this setup with win 10 and win 11.your saying your 3970x is faster than your 3990x machines? What are both pulling in Corona benchmark. I'll compare to my 3990x.
Thank you! It's been great but need sleep! So yesterday I though you was talking about the 7995WX 96 core, was reading it on my phone and like I said I need sleep, lol. The EPYC 9654 96 core seem not to be very good at all, they only pull a 31k on Corona Benchmark and that's with 2x AMD EPYC 9654 96 core CPU's. my 7980x at stock pulls a 34k. But from what I've seen I do think there is some issues with Corona and 2x CPU's.I'm in the US, but I would buy a 96 core at 50% off. Where did you find that? I saw people on eBay selling 7980X for like 3,500... But I'm a little sus about that. Sorry I haven't posted in a while, just had a new baby, and it's my first so it's a learning experience. But I got some really good updates on the 7980X. Pulling over a 39k on Corona bench and staying under 80c. I'll post results when I get home.
Oh duuude, congratulations!! That's quite the news! May the learning experience be a linear curve :)
US you say? Well Newegg has one listed for below 5k. Here is the link:

I'm looking at a chart that Supermicro provides and they've been discounted like this since basically the first week of this year. I have no idea why and even though these are clearly still expensive products they are also almost comically cheap at the same time lol.
I am beyond tempted myself. A single 96 core can replace and possibly even outperform two Zen 3 64 core Epycs at a much lower power consumption. Sheesh.
@dfcorona got any updates maybe? Totally curious to hear how the 7980x has been treating you.I'm in the US, but I would buy a 96 core at 50% off. Where did you find that? I saw people on eBay selling 7980X for like 3,500... But I'm a little sus about that. Sorry I haven't posted in a while, just had a new baby, and it's my first so it's a learning experience.

By the way, I have just noticed that roughly since the start of the year the top of the line 96 core Zen 4 Genoa is being heavily discounted (and other CPUs too). A new 9654 is commonly available at below 6000€ and I even found stores that sell them for 2500€. They used to cost like 10.000€.
I mean it is still a lot of money but we are talking about 96 cores that seemingly go above 3ghz with all cores. These are now basically 50% off.
It's the same ultimately, like setting a pass or time limit for rendering :- ) Temp limit sounds nice on paper, but could be quite fluctuating. Watt limit should still adhere to temp limit since that's hardcoded into the firmware (otherwise our PCs would burn).Thanks, I'll give it another try soon. See where it gets me and I'll post some benchmarks and temps. Even 10 percent is kind of worth it if temps are good for long animation renderings. I will be building another 7980x system soon also, decided 2 of them is a better investment compared to one 7995wx.
10perc. rendering improvement for 2X the power draw and massive temp spike might not be worth it though. Looks like the 350W was quite smartly chosen. Thank you for testing it out though :- ).
Nice build, looks like worthy investment.
700Watts at 95C degree is not bad at all with just AIO cooler :- ). So what performance did you gain?I tried it real quick for like half the benchmark, but didn't let the full benchmark finish since the motherboard was beeping like hell at me. Corona was reporting around a 37k. There is a temp limit I can set in overclocking, not sure if I should go that route or try by wattage like you say.
You can try 600Watts manual limit.
@dfcorona may I ask what the all core turbo is when running say the Corona 10 benchmark for example?The system is busy rendering right now, but once it's done I'll run it and post the results.
Oh I never cared for specific number. Laptops run for 105C for last decade and they do ("mostly") fine. At worst, you will shorten their lifespan from two decades to single decade..My experience is that most people do not setup good airflow and don't choose better cooling options. I was always big on cooling, and my systems always ran cooler than most I have seen.
With desktops, it's mostly about using the temps to gauge potential for additional performance (or silence).
But temps in fifties.. that's a bit miraculous :- ) 3990X/5990WX can run in 60s for simple multi-threaded tasks (like Corona rendering when not doing denoising or other demanding tasks). But mid-50s?
Maybe really good silicon lottery, or good room ambient (my room very quickly gets into 25C... even with all heating turned off and windows open in middle of December).
So the 7980X perhaps is really good chip in this regard and may easily eat lot more than stock 350.
But then the general temps I see on Reddit are quite bit worse in general compared to 3xxx and 5xxx series, which would make sense for Zen4 chips.
Threadripper and AMD in general always had issues with reporting accurate measurements with all the Tctl/Tdie and Offsets being taken into account differently by different applications. Ryzen Master vs HWiNfo vs HWMonitor, etc.
Checked the 7970X temps, yeah that's not doing well. So putting that idea on ice.
Threadripper with 8-dies like the 64/96C is more reasonable choice. Your reported temps still seems fairly weird, I haven't see anyone report anything that low. How are you reading/measuring these?
