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: Science
Our Science section covers all the tests that typically resemble more scientific-based workloads and instruction sets. For our 2023 CPU suite, we've also added SciMark 2.0 which measures numerical kernels and various computational routines found in numeric coding.
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.
Science
Outside of the 3DPM 2.1 AVX test (only Ryzen 7000 has AVX-512 enabled), the rest of the results are conclusive, the Core i9-13900K is very good as it dominates things in our SciMark 2.0 tests.
It is worth noting that in both 3DPM 2.1 (non-AVX) and in yCruncher, the AMD Ryzen 9 7950X is the clear winner in that battle, but even the Core i5-13600K does well against the previous Intel 12th Generation chips.

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
