The Intel 12th Gen Core i9-12900K Review: Hybrid Performance Brings Hybrid Complexity
by Dr. Ian Cutress & Andrei Frumusanu on November 4, 2021 9:00 AM ESTCPU Performance: Windows 11 vs Windows 10
There are going to be a lot of Windows 11 vs Windows 10 testing over the next few months, based on different CPUs, chipsets, configurations, and even situations where CPUs are replaced and drivers need to be reinstalled to get full performance. Windows 11 is still young, and most of our tests worked (WSL did not, will need to find out why). In this instance both OS installs were fresh and default with all updates and updated drivers. We haven't had time to run our gaming tests, those should come soon.
Windows 11 has a small effect on some of our Multi-Threaded tests, such as y-cruncher, Speedometer, and AES, but for the most part it's quite minimal.

How's that validation with Denuvo going? Nothing like upgrading to Intel and having your games suddenly start crashing.Iketh - Tuesday, November 30, 2021 - link
please, no more comments from youtuxRoller - Friday, November 5, 2021 - link
Most desktops at enterprise companies could be replaced with terminals given that most of the people are really just performing data entry & retrieval. The network is the bit doing the work.For people who need old school workstations, then I agree, but that's a damn small (but high margin) market.

Alder Lake is extremely efficient when gaming - https://www.igorslab.de/en/intel-core-i9-12900kf-c...Scroll down and you'll find a graph detailing total gaming power consumption (CPU + GPU) and CPU power consumed per fps. In both metrics, Alder Lake is doing better than Zen 3 and much better than Rocket Lake.
PC World's review - https://www.pcworld.com/article/548999/12th-gen-co... - conveys that while 12900K goes volcanic in Cinebench, it sips power in a real world workload.
It seems like Alder Lake for desktop has been clocked way beyond its performance/watt sweet spot. It should be very interesting to compare Alder Lake for laptops v/s Zen 3 for laptops.

To give a short summary for (only) CPU power consumption v/s FPS when playing Horizon Zero Dawn11900K consumes 100 watts for 143 fps
5950X consumes 95 watts for 145 fps
5800X consumes 59 watts for 144 fps
12900K consumes 52 watts for 146 fps
12700K consume 43 (!) watts for 145 fps
Intel is very, very competent with AMD. Considering that 12700K has less E cores and consumes less power, I am very curious how it would do with all E cores disabled and running only on P cores.

Sounds like there is only gaming world!In PCs it may not be considered as a egregious blunder however you're right Intel is now competitive but to previous AMD's if and only if we wink at Intel's guzzling power.
Some examples from Tom's benches:
y-cruncher
12900k DDR5 consumes 197 watts whereas 5950x consumes 103 watts.
handbrake
12900k DDR5 consumes 224 watts whereas 5950x consumes 124 watts.
blender bmw27
12900k DDR5 consumes 205 watts whereas 5950x consumes 125 watts.
Will you calculate power efficiency, please?

My 5950X uses 130-140W in y-cruncher. And @TweakPC on twitter tested lower PL1 and found the 12900k was only around 5% slower using 150W than 218W. Alderlake being power hungry is only because Intel is pushing 8 P-cores and 8 E-cores (collectively equal to around 4 P-cores according to Intel) to the limit, to compete against 16 Zen 3 cores. You can argue that it's still not as good as the 5950X but efficiency in this case is purely a problem of how much power Intel is allowing by defaultflyingpants265 - Thursday, November 4, 2021 - link
Because they need all that extra power to increase their performance a tiny bit. They're not just doing it for fun.Netmsm - Saturday, November 6, 2021 - link
Exactly 👍Netmsm - Thursday, November 4, 2021 - link
Even Ian has "accidentally" forgotten to put nominal TDP for 12900k in results =))All CPUs in "CUP Benchmark Performance: Intel vs AMD" are mentioned with their nominal TDP except 12900k.
It sounds there's some recommendations! How venal!
