Intel Core i9-13900K and i5-13600K Review: Raptor Lake Brings More Bite
by Gavin Bonshor on October 20, 2022 9:00 AM ESTCPU Benchmark Performance: Simulation
Simulation and Science have a lot of overlap in the benchmarking world. 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.
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.
Simulation
Outside of the AMD Ryzen 7 5800X3D's dominance in our Factorio testing, the rest of the results paint an interesting picture; the Core i9-13900K excels in simulations. Whether that's the addition of eight more efficiency cores over the Core i9-12900K, or that it's also partly due to increased core clock speeds, if it works, it works. The AMD Ryzen 9 7950X is also a solid contender, however, and it tears the competition a new one in our new John the Ripper MD5 test.

Yes, TDP has a meaning, and technically, neither company is using it correctly. Back in the good-ol’ days when TDP was really max power under load, it easily allowed you to spec a cooler. Clock boosts were meant to be temporary, transient states so that *on average*, you’d still lie within the thermal budget of the cooler. Obviously, we are well past that.So yes, AMD is playing it a bit loose (+31 %). But Intel is playing it ridiculous: the i9’s max power (as tested here) is 2.7x (!) their “TDP”. Reply

AMD does the same thing. dont be a fanboy Replyyh125d - Thursday, October 20, 2022 - link
If you're equating AMD going ~50w over TDP to intel going 210w over TDP, you're being the fanboy. ReplyYojimbo - Friday, October 21, 2022 - link
AMD's turbo clocking is more than 50W. ReplyYojimbo - Friday, October 21, 2022 - link
i checked and it's 60 W. That doesn't make AMD "less dishonest”. Neither company are being dishonest. It means AMD does not intend their desktop products to be used in lower power products. If you want to design a product around a Ryzen 7950X you need a 170 W cooling solution. Whereas you can put an i9 13900K in a product that can only dissipate 125 W. That's the difference between the two processors in terms if the TDPs. That's what TDP means. ReplyTruebilly - Friday, October 21, 2022 - link
I'd like to see someone run that 13900k with 120mm rad ReplyWrs - Friday, October 21, 2022 - link
I mean, it works. The processor automatically steps down the v/f curve and doesn't hiccup with a puny cooler good for 140'ish W. I tested a 12900k with a low-profile AXP-200 from my Skylake days. Performance wasn't bad, over 4GHz all 16 cores. I left all the OC settings on, or else stock E-cores would be 3.9GHz. Replynandnandnand - Thursday, October 20, 2022 - link
Go look at some efficiency curves for the 7950X and 13900K, for example at 19:00 in Hardware Unboxed's review: https://www.youtube.com/watch?v=P40gp_DJk5E ReplyYojimbo - Friday, October 21, 2022 - link
none of the companies "do” anything here. The "doing" is by the people who, though they are ignorant, write seething rants in comment sections damning the companies. Replybji - Friday, October 21, 2022 - link
This issue would be a lot less contentious if technical sites like Anandtech actually used their expertise to curate information presented. They just shouldn't even show TDP as it's simply not relevant to the end users who are reading the articles. They should have some standard benchmark they run to determine peak and maximum sustained power draws and show ONLY those values in any charts. Reply
