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: Legacy and Web
In order to gather data to compare with older benchmarks, we are still keeping a number of tests under our ‘legacy’ section. This includes all the former major versions of CineBench (R15, R11.5, R10) as well as x264 HD 3.0 and the first very naïve version of 3DPM v2.1. We won’t be transferring the data over from the old testing into Bench, otherwise, it would be populated with 200 CPUs with only one data point, so it will fill up as we test more CPUs like the others.
The other section here is our web tests.
We are using DDR5 memory at the following settings:
- DDR5-4800(B) CL40
Legacy
Focusing on our older Legacy benchmarks, the Core i9-12900KS is consistently the best performer of all of the processors on test. The additional frequency bumps to both the Performance (P) and Efficiency (E) cores make it slightly better than the Core i9-12900K.
Web
Looking at the performance in our web-based tests, the Core i9-12900KS again beats the competition pretty comprehensively, including the Core i9-12900K, the AMD Ryzen 9 5950X, and the Ryzen 7 5800X3D.

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.
