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.

Suddenly, the little cores make a lot more sense.
what for ?
Generally it was an upgrade a big one even in gaming. We have fond memories of sandy bridge but its old and slow for todays standards.
8700k is 13% faster than 2700X in 1080p and 7% in 1440p
Are you seriously saying 3930k is up there lol
8700k running at stock 4300mhz with 3200 memory is nothing special by today's standards,13% slower than that is gonna be like 30-40% slower than current upper mid range (300-400eur cpus)
do I think 3930k (oc'd with qc ram) can get there ? yes. it's not a high bar really to get close to 2700x in games.

I have a Non-K, playing Fortnite @ 1200p max settings.
I do cap at 60 FPS, cuz i only have a 60 Hz monitor.
HWInfo64 shows 40-45 watt max during gaming.
at 60hz you are never at max load with any cpu of the last 4 years.

Im sorry but the title is highly misleading!
As you might know Power=Voltage times Current.
What is listed here are Power and Current, but no Voltage.
Judging by the fact that ALD-S is 10nm, one should assume lower voltages compared to the 14nm RKL-S, hence for the same wattage, the current has to rise.
One could only assume higher power, if the voltage would be known and identical.

what for ?
Is that a serious question? The little cores are less power-hungry. So, these power estimates would likely be higher if the little cores were replaced with full size cores. Intel is likely using them to yield more performance without making the already high TDP higher.

If you have the power and current, you can calculate the voltage... Just rearrange the equation you mentioned.
Though in any case, TDP isn't actual power consumption. It could be higher, it could be lower.

Looks alright to me considering the max requirements are for a 16/24 CPU and better IGPU.
I actually expect it to consume less than 11k in real tasks due to better core management.
Or I can just start screaming like a parrot just to make a fuss.
