Alder Lake consumes up to 28% more energy at peak usage than Rocket Lake
The power needs for Intel's twelfth-generation Alder Lake CPUs have been revealed by China's FCPowerup, a website dedicated to power supply evaluations. This source has previously given accurate information on Nvidia's new 12-pin pcie connector, including the original schematic and pictures.
The tables appear to be from an Intel paper, most likely aimed for power supply manufacturers. It is a problem with the 12V2 rail, which delivers power to the CPU. The table contains parameters for 35, 65, 125, and 165 watts, the latter of which is only relevant to hedt processors from the tenth generation. There is no indication that Alder Lake will include high-performance desktop CPUs.
The continuous flow ratings for Comet and Rocket Lake remain unchanged. Peak values have been increased by up to 28% on the 125W models and by 15% on the 125W models. The latter refers to the peak power usage, which happens often at startup. This is critical information for power supply manufacturers because when the power supply cannot match demand, it frequently shuts down automatically.
Recently, several Alder Lake specifications and benchmarks have appeared online, as has the first purported Z690 motherboard. Now that the criteria for power supply appear to be communicated with manufacturers, all indications point to an imminent formal debut.

peak power draw difference can be even bigger
Nah, ~40-50W was for 10 series, Rocket Lake uses at least 80W without v-sync while doing the same thing with ~10% more fps. Really dumb architecture.

good grief
pass on this
i may be tempted to get a rkl-s next year if it goes on sale like 10th gen and pcie4 drives (the good ones) drop from 250eur for 1tb
adl-s will be ridiculously expensive and power hungry like the devil.

well,you'd never buy intel anyway,even at twice as good value.
all i hope for is 11th gen dropping as low as 10th at some point.they're a waste of silicon indeed,but name a price low enough and they'll be a great buy.

So that's still only 51 watt compared to my current 11700 which uses only 40 watt during gaming.
Not bad.
