The Intel Core i9-12900KS Review: The Best of Intel's Alder Lake, and the Hottest
by Gavin Bonshor on July 29, 2022 8:00 AM ESTCPU Benchmark Performance: Encoding and Compression
One of the interesting elements on 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.
Video transcoding as a tool to adjust the quality, file size and resolution of a video file has boomed in recent years, such as providing the optimum video for devices before consumption, or for game streamers who are wanting to upload the output from their video camera in real-time. As we move into live 3D video, this task will only get more strenuous, and it turns out that the performance of certain algorithms is a function of the input/output of the content.
We are using DDR5 memory at the following settings:
- DDR5-4800(B) CL40
Encoding
In the Encoding and Compression section of our CPU benchmark suite, the Core i9-12900KS was either around the same or performed slightly better than the Core i9-12900K. The Core i9-12900KS was also consistently better than the AMD Ryzen 7 5800X3D in all encoding tests except in our WinRAR 5.90 benchmark.

It's not the CPU that's bent. It's the ILM that is the issue.charlesg - Friday, July 29, 2022 - link
Meh. I like my 1.5 year old 5950X thank you.Alistair - Friday, July 29, 2022 - link
The 12900KS has already been discontinued at our store, as nobody bought one. Terrible chip.Don't forget that Ryzen 7000 series is releasing in a few weeks only, and will beat it soundly, with half the power consumption.
But even if you were buying today I'd get the 5800X3D which is now on sale. $390 at our store. Much more popular.

Emulation with the 12900KS is a dream though... that's the one high spot for me, as Ryzen is still not a great emulation chipI hope Ryzen 7000 fixes this in the Dolphin benchmark.

Is emulation worth the heat, power use, and cost?Alistair - Saturday, July 30, 2022 - link
Emulation is single core heavy, there isn't a heat or power use issue.Tunnah - Saturday, July 30, 2022 - link
I have a 3700X that runs switch emu at 60fps, so I don't see why more single core performance is any more necessary. You're not unlocking something previously undoable, you're just paying a shedload of money for a few more FPS.Silver5urfer - Saturday, July 30, 2022 - link
RPCS3, Xenia, PCSX2Ryzen cannot run games vs 10th+ gen processors in performance. You do not need to dump a ton of cash. A 10700K can perform much better in either of these and that is available for peanuts now. Z590 is also super cheap.

I heard that if anyone upgrades to a regular 13900K that this chip will be faster then the current 12th Gen KS model?PeachNCream - Friday, July 29, 2022 - link
Burn the planet! 241W TDP not high enough for my video gaming habit to destroy our world in the name of keeping me amused and allow me to brag to my superficial circle of so-called friends on Discord and disinterested coworkers about how many more FPSes I get in Fortnite!
