The Intel Core i9-12900KS Review: The Best of Intel's Alder Lake, and the Hottest

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.

peak power was 276 watts...Carls Car - Saturday, July 30, 2022 - link
Peak power can get way higher.dicobalt - Saturday, July 30, 2022 - link
I'm sure kilowatt PCs will cause no electrical problems at all. At this rate people will need to hire an electrician to make sure it's safe. It's not like DIY repairs in hurricane and flood zones ever cause fires or deaths.Tunnah - Saturday, July 30, 2022 - link
It's just so violently 'Murican. Pure horsepower and engine size, drinks tons of fuel and is inefficient as hell. The alternatives do way better with less power and cost you less to run. It's just so..brash.But people will buy it because they wanna wave their willys.

All the top CPU designs are American ;pGrapple - Saturday, July 30, 2022 - link
Would have loved to see one 12th Gen Core i9 at each power level in the charts — i9-12900T, i9-12900, i9-12900K, and the i9-12900KS — to see how the power/performance looks across the gamut.stephenbrooks - Saturday, July 30, 2022 - link
Yes - the 12900T looked the 2nd-most-interesting chip to me in this lineup, I'm curious what this does at lower power.I think the 12900F looks best because: it's the cheapest, doesn't have a iGPU you won't use, uses less power but not a particularly bad regression on clocks.

but the 5800x3d is far ahead of the 12900fhansip87 - Sunday, July 31, 2022 - link
Those heat output could be linked to the LGA 1700 locking issue. i bet those who bought such a chip won't mind using the aftermarket bracket.
