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.

was there really any other option ? not really.
and frankly,for gaming 3930k->2700x is a sidegrade at best.
Its not true. I had Sandy-E 3930k before i went to amd again.

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.
You play Tetris or pacman? Because it uses 90-130W normally on gaming at 1080p.

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

Suddenly, the little cores make a lot more sense. And this is coming from someone who was looking forward to them regardless.

Back then, the Phenom II x6 was a compelling product if you cared about multi-threaded performance.

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.
Its not true. I had Sandy-E 3930k before i went to amd again.
