AMD Zen 4 Ryzen 9 7950X and Ryzen 5 7600X Review: Retaking The High-End

Simulation and Science have a lot of overlap in the benchmarking world, however for this distinction we’re separating into two segments mostly based on the utility of the resulting data. The benchmarks that fall under Science have a distinct use for the data they output – in our Simulation section, these act more like synthetics but at some level are still trying to simulate a given environment.
One of the interesting elements on 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 to for software security.
Video transcoding as a tool to adjust the quality, file size and resolution of a video file has boomed in recent years, such as providing the optimum video for devices before consumption, or for game streamers who are wanting to upload the output from their video camera in real-time. As we move into live 3D video, this task will only get more strenuous, and it turns out that the performance of certain algorithms is a function of the input/output of the content.
We are using DDR5 memory on the Ryzen 9 7950X and Ryzen 5 7600X, as well as Intel's 12th Gen (Alder Lake) processors at the following settings:
- DDR5-5200 CL44 - Ryzen 7000
- DDR5-4800 (B) CL40 - Intel 12th Gen
All other CPUs such as Ryzen 5000 and 3000 were tested at the relevant JEDEC settings as per the processor's individual memory support with DDR4.
Simulation
Starting with the Dwarf Fortress section of our simulation suite, the performance of the Ryzen 9 7950X and Ryzen 5 7600X is inconsistent, to say the least. In the smaller of our three Dwart Fortress tests, there's around 2-3% difference between the Ryzen 7000 chips, the Core i9-12900K and Core i7-12700K, and AMD's impressive Ryzen 7 5800X3D with its incredibly large 96 MB pool of cache to play with.
In the larger Dwarf Fortress workloads, and the Alder Lake based Core i9-12900K, the Core i7-12700K and the Core i5-12600K show better scope for performance, with the exception being the Ryzen 7 5800X3D which due to its large 3D V-Cache, keeps the pressure on Intel.
Looking at performance in our Factorio benchmarks, the AMD Ryzen 7 5800X3D with its 3D V-Cache is streets ahead of the competition, with both the Ryzen 9 7950X and Ryzen 5 7600X both lagging behind considerably. Comparing Ryzen 7000 to Intel's Alder Lake, Alder Lake has the overall advantage here, even with the many optimizations and improvements that Zen 4 brings to the table.
Encoding
Focusing on encoding, and the Ryzen 9 7950X is the clear winner, beating the Core i9-12900K in all but one of the Handbrake tests (1080p30). The Ryzen 5 7600X trades blows with last generation Ryzen 7 5800X, which is an improvement within itself, as the Ryzen 5 5600X does lag behind the rest of the pack.

Because MS is far less trustworthy then intel, and has been making moves to block, censor, and lock down everything whenever possible via hardware. Pluton should scare people, giving MS the keys to your hardware is a nightmare. ReplyIketh - Thursday, October 6, 2022 - link

Hi. What happened to RDR2 at 4K, please? ReplyRyan Smith - Monday, September 26, 2022 - link
RDR2 did not behave itself properly at 4K on some of our test systems. We're still trying to isolate why. ReplyAndrewJacksonZA - Monday, September 26, 2022 - link
Thanks Ryan. I'm really interested in that and GTA V at 4K. Thank you! :-) Replypiskov - Monday, September 26, 2022 - link
Please add current Apple CPUs if tests allow it. ReplyGhwomb - Tuesday, September 27, 2022 - link
Yes. That would be nice. Especially since Linux and openBSD support is coming along nicely on M1 and M2. Making it a viable option for non-macOS users. Replyddhelmet - Monday, September 26, 2022 - link
No Dolphin benchmark? ReplyHarry_Wild - Monday, September 26, 2022 - link
Buying Zen 4 7600X and motherboard, DDR5, MvME on Black Friday and/or CyberMonday! Might be $1K! Use my current graphics card, PSU and SFF case. Still a lot of dough! Reply
