Intel Core i9-12900K 36% Faster Than Stock in Maximum Turbo Power Mode
The recently announced Intel Core i9-12900K is set to launch on November 4th alongside the i7-12700K, and i5-12600K which is the date when we will see reviews for the processors released. We have already seen numerous leaks regarding the processors performance leading up to the announcement and we have now received some new leaked performance figures for the processors when operating in Maximum Turbo Power (MTP). The MTP is defined by Intel as the maximum sustained power dissipation of a processor compared to TDP which is the base power draw. The performance difference between these two power modes has been revealed from Cinebench R20 multi-threaded results posted by Wofstame the Gaming Desktop Product Planning Manager for Lenovo China.
The Intel Core i9-12900K scores 7492 points when running at its TDP of 125 W and 10180 points or 36% faster when operating at the MTP of 241 W. This performance difference is less notable for the other processors with the Core i7-12700K seeing a 30% improvement between its 125 W and 190 W power modes while the Core i5-12600K sees a 10% improvement from the 125 W TDP to 150 W MTP. Intel appears to be extracting the maximum performance from their Core i9-12900K with diminishing returns from the increased power budget compared to the other processors.

We are approaching Captain Obvious territory here
*edited originally had two thoughts in one sentence*
Benchmarking for high performance? Of course "PL2" is not overclocking, it's on by default on motherboards! Measuring power consumption? Of course TDP guidance from Intel is observed. Measuring power consumption while in "PL2"? We'll let Anandtech do that, and they don't get free CPUs any more for doing that...
36%+performance for 100%+ power? Sure no.
If the little cores were as good as they say, they would do a 4P + 24E design with the same area.
If they can't dissipate fast enough, you can run more power through the chip, but it'll just not work within safe parameters even in the typical 24/7 Intel test bed of water chiller plus nuclear plant.
Aaand... boy what a surprise, Intel chips still get hot on the fabled 10nm that is ALSO clocked way out of its comfort zone like 14nm was. You don't say.
Yeah Alder Lake might consume more power than Ryzen (when under turbo and sustained load) but it will still put pressure on AMD to react. If the 12600k beats the 5800x and the 12700k beats the 5900x (or at least gets close or trades blows) for less money, that will put pressure on amd. Also, Z690 is a big platform upgrade over z590 and also x570/b550. Some Z690 boards come with thunderbolt, aquantia 10gbps lan, 4 pcie4.0 m.2 slots, and so on. Some asus boards even come with a pcie5.0 m.2 slot. X570 is good, but Z690 is very competitive vs x570, something that could sway some prospective buyers to purchase an Alder Lake system over zen.
