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.

Bit disappointing that the memory controller only supports DDR5-5200, considering that JEDEC compliant DDR5-6400 RDIMMs are available.Ryan Smith - Monday, November 20, 2023 - link
At the end of the day it's the same I/O die as Genoa. So it comes with roughly the same restrictions.TEAMSWITCHER - Monday, November 20, 2023 - link
Not surprised by this at all. My 3960X Threadripper system was never able to run 64gb (16gb x 4) at even the promised DDR4-3200 speed. I tried three different RAM kits and even a different CPU (replaced by AMD) and the problem never went away. In the end I believe it to be motherboard issue, it was simply incapable of running stable with any RAM faster than DDR-3000.After spending so much on the ASUS Zenith II Extreme Alpha motherboard, 64GB of DDR-3600 RAM, and a $1400 CPU, the end result was very disappointing. Support from ASUS, AMD, and G-Skill was a long process, and eventually I had to just accept what was working and move on.
Ultimately, I don't believe that AMD and ASUS can properly deliver and support any HEDT platform that is worth the money they ask for it. I sincerely wish Intel would return to this segment, as I never had a problem with my X99 Deluxe II motherboard.

Intel is definitely in HEDT with their xeon w-2400 chipsStormyParis - Monday, November 20, 2023 - link
I've blacklisted Asus. Lots of issues with both specs, reliability, and service.vfridman - Monday, November 20, 2023 - link
I have two systems with 3990X and two systems with 3970X, ASUS Zenith II Extreme Alpha motherboard and 256GB of 3600 speed G.Skill RAM in each system. All runs perfectly and completely stable, even with maxed out PBO overclock. I regularly run compilation jobs that require almost entire 256GB of RAM and never experienced any problems. I suspect you got unlucky with your CPU memory controller.Mikewind Dale - Tuesday, November 21, 2023 - link
I have a ThreadRipper Pro 3950X on a Supermicro WRX80 motherboard. I run 8x64 (512) GB of Supermicro-branded DDR4 3200 ECC RDIMM without a problem.Adam7288 - Wednesday, November 22, 2023 - link
Same exact config! Ram Bros.tygrus - Saturday, January 6, 2024 - link
How are you going with those >200GB matrices & statistics?Many years ago I had to use raw frequency stats, then a program to generate blocks of SAS code that could analyse cross-tab by cluster (weighted) with smaller subsets of interest from every possible combination (multi-morbidity data). Making sure the stats methods still gave correct results. Divide & conquer to fit in limited RAM of circa 2013 computers. In those days it was mostly constrained by single thread & disk/network IO speed (~100MB/s).

Ya know.. I have yet to build an AMD system that didn't suffer from some kind of issue. I don't think I'm unlucky either. I need to stop buying AMD gear thinking... "this time will be different." Because it never is.
