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.

Your test results make absolutely no sense, none.MetalScythe - Sunday, April 9, 2023 - link
Especially compared to -every- other publication that’s reviewed this CPU. Going by this review, you’d think it’s crap at gaming. Pure insanity.zodiacfml - Thursday, April 6, 2023 - link
with this logic, its the i3s and 5600g are the winners as the performance/price is highest. I'm quite impressed they're holding up well even at the lowest resolutions or fastest GPUs.Ruklaw - Thursday, April 6, 2023 - link
Are the power readings derived from what the processor itself is reporting?My impression is that AMD processors tend to under-report, as the low power readings from the cpu don't quite seem to match up with the readings of whole system power where I've been able to find them.
Obviously motherboard is going to be a big factor in how much power the system uses but with all else being equal the system power is going to be more representative of what we actually have to deal with (in terms of heat and energy cost).

I’m genuinely baffled by your testing, you kneecapped Intel to give AMD a win; who the hell buys a 13900KS and uses crap memory?Worst test I’ve ever seen.

The memory we used, that is following a long-standing testing policy with the site. We test CPUs with the fastest memory they officially support. Overclocked memory a) Voids your processor warranty, and b) Isn't guaranteed - which is to say that you can't RMA a chip because it doesn't overclock to some specified frequency.We've had discussions with AMD and Intel on the matter before. If they change these two policies, we'd be happy to update our testing policies to match. Otherwise, our preference is to stick to settings that won't break your processor, and represent a level of performance that all chips will attain, rather than a level of performance that a subset of chips may attain.

Wel. Your comment can get to the usual list of worst as usual.It is clearly explained why and used for a long time for years.
Who the hell buys the worst cpu ever the 13900ks anyhow... Yes stupidity exists... Power consumption will solve all issues :)
Anyhow scaling works on all platforms and often depending on game.

I’m guessing this is the very same Nerdhard from WCCFkek…MetalScythe - Sunday, April 9, 2023 - link
Anandtech really should update the games they use to benchmark…MetalScythe - Sunday, April 9, 2023 - link
Going by this review, and the unexplained blatantly elderly games used to review the CPU; you would think it’s an absolute dog at gaming.Reality couldn’t be farther from the truth. This site has fallen so far from relevance… it’s saddening.
