Intel Core i9-13900K and i5-13600K Review: Raptor Lake Brings More Bite

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 Core i9-13900K, the Core i5-13600K, the Ryzen 9 7950X, and Ryzen 5 7600X, as well as Intel's 12th Gen (Alder Lake) processors 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
Identifying what core comes where in our rendering tests, both the Core i9-13900K and Ryzen 9 7950X sit comfortably at the top of the tree. Depending on the test, it’s a consistent battle for rendering supremacy. Where things aren’t as close are in our POV-Ray and V-Ray tests, where the Core i9-13900K has a distinct advantage; likely down to having eight more logical cores than the 7950X.
Encoding
In our encoding tests, interestingly the Core i9-13900K looks to have the advantage in compressing files with 7-Zip. It’s a little different for AMD as the Ryzen 9 7950X decompresses the data better, with the overall combined advantage going to AMD in this particular test. In our updated x264 benchmark, Intel takes the lead in 4K encoding, while AMD has the lead in 1080p encoding; both are equally viable options, however.

Did you even read the article? Intel advertises the 13900k as a 253w chip. It drew 32% more than it advertised while AMD advertises its 7950x as a 170w and it drew 30% more than they advertised.“Processor Base Power
125 W
Maximum Turbo Power
253 W” Reply

You're comparing the PL2 of one chip with the TDP of the other. Also, the article mentioned the motherboard may have something to do with ignoring the PL2 on the 13900k.If the chip can't dissipate PL2, it'll incrementally step down to TDP gracefully. It's like you're complaining your 130mph sedan went 165mph on the race track... Reply

Oh, so the motherboards are the culprits for overclocking the CPU's to new height of financial success, not Intel? ReplyWhatYaWant - Thursday, October 20, 2022 - link
7600x seems a bit overpriced, doesn’t it? Replyingwe - Thursday, October 20, 2022 - link
Yeah it does. $250 seems like a better price--maybe even a bit lower. It will probably come down. I just picked up a 5600 for $125 though so I am set. I suspect that the price will only come down on the 7600x once the stock of 5 series is cleared out. Replymeacupla - Thursday, October 20, 2022 - link
I am happy that Raptor Lake offers stiff competition to Zen 4. Hopefully AMD brings down the price of 7600X, and hurry up and launch their B650 boards Replycaqde - Thursday, October 20, 2022 - link
?? B650 is released? At least on Newegg and amazon you can purchase a selection of B650 motherboards today. Out of the 23 boards listed, 1 is out of stock and 5 are preoders for the 21st or 27th. So that leaves 17 boards that you can purchase today that are in stock, the in stock boards go from 170-350 (Asrock 650M PG Riptide and Gigabyte B650E Aorus Master respectively). But yeah AMD should and from what I have heard can lower Zen 4 prices to compete with Intel's prices. Replyhaukionkannel - Thursday, October 20, 2022 - link
When AMD release 3d cache versions, it will reduce the prices of normal versions.How much, is interesting question. I expect that AMD also will release 7600 to compete with intel in price, so 7600x may not come down a lot. Reply

Oh, B650 is out already? I saw no news coverage of them, so I thought they were still waiting to be released. Replytechguymaxc - Thursday, October 20, 2022 - link
You list Handbrake under legacy tests however, either the graphs or mislabeled or the tests are not included. Did you test these CPUs with Handbrake? If so, please post the results. If not, please consider testing and updating the article. This is the only workload that matters to me, and the number one reason I come to Anandtech for CPU reviews/benchmarks. Reply
