The Intel Core i9-13900KS Review: Taking Intel's Raptor Lake to 6 GHz

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 12th and 13th Gen Core parts, as well as the Ryzen 7000 series, at 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
Both the Core i9-13900KS and Core i9-13900K trade blows regarding rendering performance. In some instances, such as POV-Ray, it seems that the slight thermal throttling of the 13900KS did hinder things here a little, but in Cinebench R23, the Core i9-13900KS shone in the single-threaded test.
Encoding
When it comes to encoding, the Core i9-13900KS takes away as many wins as it does losses against the Core i9-13900K. The Core i9-13900KS does take a big win in our WinRar 5.90 benchmark by a solid 3.3 seconds.

They won't, but for a practical reason. It's an always online, frequently updated game, and test data would only be relevant for a single, back to back comparison between parts. No way to accurately compare to previous test results.Peskarik - Saturday, January 28, 2023 - link
Exactly!Please add Microsoft Flight Simulator, Anandtech!!!

There was a screenshot floating around not too long ago (from Anandtech iirc) showing why not - the activation process is a nightmare if you try to flip it between machines for testing. The want to use it, MS stand in the way.scottrichardson - Friday, January 27, 2023 - link
I know this is primarily a PC/Windows oriented review but I would have loved to have seen the M2 pro/max included in here. I know that it would have been smoked in most of these benchmarks, especially multi-core, but it would still be interesting to see the power usage and relative performance. Whether we want it or not, there’s a 3rd player in the CPU game now!dontlistentome - Saturday, January 28, 2023 - link
There's a 3rd player taking part, but in a different game. If it can't run the same software or platform, it's irrelevant other than for comparing instruction sets.Tunnah - Friday, January 27, 2023 - link
1/3rd more power for single digit performance increase, how very Intel.Peskarik - Saturday, January 28, 2023 - link
AMD Ryzen 9 7900 wins for me.Carmen00 - Saturday, January 28, 2023 - link
10-20Mhz extra on average, for the "Favoured Cores" only, and for an additional $110 and 25W more. I know there are plenty of Greater Fools in the tech space, but surely there is a limit to how much even they will tolerate?albie_ - Saturday, January 28, 2023 - link
"The peak power figures from our power testing show that the Core i9-13900K drew an impressive 359.9 W at full load."I'm dumbfounded by this statement. Is this supposed to be selling point and good to have? What sort of tech journalist are you?

"What sort of tech journalist are you?"The sarcastic kind.
That statement was fully tongue in cheek. Intel made a consumer desktop chip that draws 360 Watts. It's all a bit silly, innit?
