The Intel Core i9-13900KS Review: Taking Intel's Raptor Lake to 6 GHz
by Gavin Bonshor on January 27, 2023 10:00 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 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.
Science
Our science-focused benchmarks highlight the fact the Core i9-13900KS and Core i9-13900K are both very similar in regard to performance. Outside of the 3DPM v2.1 AVX test where AMD gains the advantage in actually supporting AVX-512 instruction sets, the additional bump to base and turbo clock speeds doesn't yield too much benefit here.

It is doing weird and crazy things with all my chips. On half of them, it will even refuse to POST. I've reached out to MSI UK, but I'm yet to receive a response. At this point, I may as well re-test all the 13th Gen SKUs on another board for parity purposes.PeachNCream - Friday, January 27, 2023 - link
I could think of better things to do with 360W of power like running ALL of the lights in my home, running my laptop at full load, charging and using my phone, and feeding the router necessary to support my internet connection (and I would still have close to 100W left for other things). With a 13900KS, you get a CPU and nothing else, not even cooling for said processor let alone the rest of the computer hardware in the system required to support it. Enthusiasts are apparently idiots with bottomless lines of credit that Intel thinks will brainlessly pay interest to VISA and, sadly, they might be right.jgrimm2364 - Thursday, February 2, 2023 - link
I paid cash for mine and love it. Cheaper than the i74930k I built 8 or 9 years ago. When a processor kicks most others butts for that long, it's worth paying for. It's like buying a performance car vs a grocery getter. It performs!PeachNCream - Sunday, February 5, 2023 - link
Car people "logic" also escapes me because of how self-centered it is to expend more of our limited energy resources than necessary to accomplish something, but huge pickup trucks, gigantic SUVs, and pointlessly overpowered cars are around in large numbers so at least you can safely say you followed the school of fish into the proverbial mouth of a demise of your own making as you suffer while living on a trashed planet.

320w. Just disgusting waste.This is the most retarded CPU since the dying days of the Pentium 4.

I think you have blotted the 9590 out of your memory.Jorgp2 - Saturday, January 28, 2023 - link
Or the 7950x which still uses 260wemike09 - Friday, January 27, 2023 - link
Please add Microsoft Flight Simulator to your benchmark tests. Few games are so demanding on the CPU as MSFS. When you look at the posted gaming benchmarks, there's little difference between most CPUs for each game benchmarked. Throw in a game that really showcases what a CPU can do in a CPU demanding title.ballsystemlord - Friday, January 27, 2023 - link
Is MFS really CPU intensive? Or does it just use one thread much like Quake III? If that's the case then you can just benchmark ioquake or OpenArena.Or for an even more hilarious result, why not try a multi-threaded python program? Then you could watch that CPU intensive GIL (Global Interpreter Lock) wreak havoc on the tested CPUs via python's polling process.

PS: You'd have to request a high frame rate, like 500fps, for a Quake III client to saturate the CPU.
