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.

performance per watt for these CPUs is abismall!bug77 - Friday, July 29, 2022 - link
Which is weird, because high-end CPUs (and GPUs, for that matter) are usually hallmarks of efficiency. Right?But yeah, Alder Lake can take so much punishment, your PSU might cave in before the CPU does...

Sadly AMD is also headed in this direction with their new CPUs (Zen 4)...... 5.5 GHz and 70% higher TDP for what, 40% or so better MT performance?Apples high end CPU and GPU performance scales quite well with power. They just throw a lot more silicon at the problem, but it is effective.

Eyup, this is another Netburst..bennyg - Monday, August 8, 2022 - link
When you get up to 5ghz, yeah, but OC has always been that way, turbo boost is just factory auto OCDown at 80W in mobile the perf per watt looks far better for the 6p8e parts
It's all Ohm's fault for that law of his

Huh. Makes you wonder how a stock 12900KS would perform under Dry Ice since I doubt any phase change cooler can keep up with the 400 watt heat output.ddhelmet - Friday, July 29, 2022 - link
Factoria updates per seconds are too low.healbunny - Friday, July 29, 2022 - link
stock voltage is way too high, please try undervolt. my 12900ks with undervolt able to get P core all core 5.3Ghz, Ecore 4.2Ghz (vcore 1.2v). 2 core boost is 5.6Ghz at 1.3v vcore. All core full load in cinebench r23 consume 240w, cpu package temperature around 80C. Single core consume around 48W, 53C. (using Msi K360 aio). Score for R23, multi 30006 pts, single 2143pts.Oxford Guy - Saturday, July 30, 2022 - link
You are clearly unfamiliar with their justification for only using JEDEC RAM settings. Undervolting is more complex than picking a vetted XMP profile.Carls Car - Saturday, July 30, 2022 - link
healbunny didn't mention XPM at all.
