CPU Benchmark Performance: Rendering And Encoding
Rendering tests, compared to others, are often a little more simple to digest and automate. All the tests put out some sort of score or time, usually in an obtainable way that makes it fairly easy to extract. These tests are some of the most strenuous in our list, due to the highly threaded nature of rendering and ray-tracing, and can draw a lot of power.
If a system is not properly configured to deal with the thermal requirements of the processor, the rendering benchmarks are where it would show most easily as the frequency drops over a sustained period of time. Most benchmarks in this case are re-run several times, and the key to this is having an appropriate idle/wait time between benchmarks to allow for temperatures to normalize from the last test.
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 to for software security.
We are using DDR5 memory on the Ryzen 7 78000X3D and the other Ryzen 7000 series we've tested. This also includes Intel's 13th and 12th Gen processors. We tested the aforementioned platforms with the following settings:
- DDR5-5600B CL46 - Intel 13th Gen
- 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.
Rendering
As expected, the Ryzen 7 7800X3D delivered the performance we anticipated in our rendering tests. While we did observe instances where the performance was similar to that of the Ryzen 7 7700, the most significant takeaway was that the Ryzen 7 7800X3D outperformed the Ryzen 7 5800X3D, as it is the direct successor to that CPU.
Encoding
When we examine the encoding performance of the Ryzen 7 7800X3D, we see that it performs on par with the Ryzen 7 7700. Additionally, the Ryzen 7 7800X3D is competing with Intel's Core i5-13600K, which is still less expensive but is a more versatile chip with 14C/20T.

It’s because Anandtech’s gaming benchmarks are using insanely outdated games.Do your due-diligence and read other publications’ reviews of the chip. They’re much faster at gaming than this “review” makes them seem.

Looking at the results in this review, are we certain that there was no "core parking driver" contamination? Because the 7800X3D seems really slow where it shouldn't be.Gamers Nexus had this issue and had to do a clean install to get their 7800X3D to work properly and not park cores.

Hi Meacupla, I can confirm I had no core parking driver issues, but I did use a fresh install of Windows 11 as per AMD's suggestion. I knew that issues could arise before even installing the CPU, but as I confirmed earlier, I didn't notice any odd behavior.Can I ask, where do you believe the 7800X3D is slow in our testing?

The cases where it loses from the 5800X3D maybe.I find it also fascinating how often the 7600x is faster. And isn't mentioned when you make the "Cheaper CPU will enable you to buy a better GPU" point.
But that's a different story.

this partAll the other reviews I've seen put the 7800X3D ahead by a wide margin in gaming results at 1080p and 1440p when compared against a 7600X and 7700X.

Again, it’s because the games Anandtech uses for game reviews are incredibly outdated.I mean… GTA V in 2023!??

People need to stop bitching about memory speed. 7000 series are hard-capped at 6000 MT/s (up to 6400 MT/s with questionable stability) and regular non-3D chips barely show the impact of faster memory. For these 3D V-cache chips, faster memory is literally a waste of money. As a matter of fact I'd argue it is one of the benefits of using these chips that you can get away with budget memory.roboiii - Thursday, April 27, 2023 - link
If you do a decent amount of reading/video watching it's fairly evident that 6000 @ 30 is the "sweet spot". I think rather than "bitching" people want to see their tech sources engage in actual tech that's applicable to the part in question. x3d is a part designed & marketed to gamers, who typically have a rig with high end parts and utilize the highest memory settings to achieve better performance.tjrneal - Thursday, April 6, 2023 - link
The borked 7950x3d results are still there for Dwarf Fortress and Factorio.Gavin Bonshor - Thursday, April 6, 2023 - link
They are because they are the figures we got when running the original test suite. I did run the suite a couple of times to see where the PPM driver got things wrong, and the 7950X3D running on the 3D V-Cache enabled CCD performs as well as the 7800X3D does in Factorio and Dwarf Fortress.
