TR 7000 vs. Intel: Encoding
One of the interesting elements of modern processors is encoding performance. This covers two main areas: encryption/decryption for secure data transfer and video transcoding from one video format to another.
In the encrypt/decrypt scenario, how data is transferred and by what mechanism is pertinent to on-the-fly encryption of sensitive data - a process by which more modern devices are leaning towards for improving software security.
We've updated our list of encoding benchmarks for our 2024 CPU suite to include some of the most relevant and recent codecs, such as AV1, HEVC, and VP9. Not only this, but we have also included FLAC audio encoding as well as WebP2 image encoding into the mix to show not only how the latest processors perform with these codecs but also to show discrepancies in performance throughout the different segments.
We are using DDR5-5200 RDIMM memory on the Ryzen Threadripper 7980X and 7970X as per JEDEC specifications. For Intel's Xeon W9-3495X, we are using DDR5-4800 RDIMM memory as per Intel's JEDEC specifications. It should be noted that both platforms are run with their full allocation of memory channels, eg, TR7000 in 4-channel and Sapphire Rapids in 8-channel.
Below are the settings we have used for each platform:
- DDR5-5200 RDIMM - AMD Threadripper 7000
- DDR5-4800 RDIMM - Intel Xeon Sapphire Rapids WS
- DDR5-5600B CL46 - Intel 14th Gen
- DDR5-5200 CL44 - Ryzen 7000
Starting with the WebP2 Image encoding tests, the Ryzen Threadripper 7980X and 7970X perform well compared to the other chips we've tested. Interestingly, in the SVT AV1 encoding using the fastest preset, the desktop chips with the faster core frequencies win. The tables turn using the mid preset, with both Threadripper 7000 chips sitting on top of the charts.
In the SVT-HEVC benchmark, the Intel Xeon W9-3495X sits at the top of the list, and the same is prevalent in the VP9 encoding benchmark. In the FFmpeg 6.0 benchmark with x264 and x265, the desktop processors with the faster cores win in this situation, with the Core i9-14900K and the 6.0 GHz boost core frequencies playing a bigger hand than simply having more cores.
Looking at 7-Zip performance, both the Threadripper 7980X and 7970X are vastly superior to the Intel Xeon W9-3475X and the flagship desktop chips, including the Core i9-14900K, Ryzen 9 7950X, and Ryzen 9 7950X3D.

One of the most common issues of AMD is sketchy performance and stability with non samsung chips.If you ram had hynix or similar chips..it would usually not post at the advertised max speed.
As soon I moved to Samsung chips in all my AMD builds, all problems went away.

Just unlucky. Should RMA the mb. Asus imho, is still the best for HEDT whether AMD or Intel.clsmithj - Sunday, December 31, 2023 - link
I have a 3960X Threadripper on a MSI TRX40 Creator, and a 2990WX Threadripper on a MSI X399 MEG Creation board.Both system use 4 sticks of Kingston 64GB (16GB x 4) DDR4 3200 dual rank memory (HyperX Predaor/Fury) that worked fine at their C16 3200 MT XMP rate.
I used DRAM Calc app and managed to get the RAM of my 3960X to run stable at gear 1 C16 3800 MT with UCLK=MCLK set 1900Mhz.
The ZEN2 CPU is definitely capable of this high memory OC. I've watch Buildzoid clips of him showing how with ZEN2 TR it can go even higher than 3800.
My ZEN+ 2990WX I have running at Gear 1 C16 DDR4-3466 speed, and I checked ZenTimings that revealed its UCLK=MCLK is at 1733Mhz.
The high memory clocking is doable you do need a good motherboard, but I always observed the TRX40 boards having a fast amount of decent boards with high amount of VRM phases.
It was the X399 boards that only had a total of two good boards, which was either the MSI MEG Creation or the ASUS ROG Zenith Extreme.

Where have you seen JEDEC compliant 6400 RDIMMs? The highest I've seen is 5600.Rοb - Wednesday, November 29, 2023 - link

I was able to run my 3960X with G.Skill Trident Neo 4x16GB 3600CL16 (B-die) at 3600CL14 and/or 3766 CL16 (Asus ROG Strix TRX40-E Gaming) for weeks without any problems.Broke down the processor about two months ago. Touched accidentally USB-A -port with an USB-C -cable and the processor no longer booted (or booted and went trough all but the last POST test and then stuck - tried two different MB) :(
Put all components into a new 5800X3D system and got 4x16GB memory to work @3600CL16.
Now considering the new 7960X.

So looks like the difference between your system Demu and Teamswitcher is you paired it with high-quality memory.Which is no surprise and it's why I never go cheap on memory.

It's not about cheap or expensive, it's if you got Samsung B-die or not.I have G.Skill F4-3600C18-16GVK, and it only works at 3200 CL18. Why? because I was told it would be Samsung B-die, but it turned out to be SK Hynix, and the AM4 platform doesn't like working with anything other than Samsung B-die.

I have B-die and that is what I'm talking about when I said don't buy cheap memory. B-die = expensive but you get what you pay for and it just works. And you should have done your own research I would have caught the memory was Hynix before purchase.meacupla - Monday, November 20, 2023 - link
That's the thing though, I did do my research.
