Wow core i4900k and 14900ks editions rumored to have 6.0 ghz and 6.20 ghz clock speeds ! I thought we were had hit a 5 ghz ceiling with current tech. What a time to be alive !

The power draw is going to be insane though! It feels like the Pentium 4 all over again, except no one is really objecting to skyrocketing power usage, and not just for CPUs... GPUs, RAM, even SSDs!

  People only seem to care about power consumption when it’s AMD

    Rocket Lake was criticized for it. But Alder Lake/Ampere and everything after all feels insane and unopposed. Ryzen/Radeon 7000 is kinda turbo happy too, just not as bad.

  125W at load isn't that much at all. 6ghz is crazy. We really are living in the future! Edit: why does TFA say 12W for all three processors?

    For the 13900K, its more like 300W over a 69W idle! https://www.guru3d.com/articles-pages/intel-core-i9-13900k-review,6.html https://www.guru3d.com/articles-pages/intel-core-i9-13900k-r...

      Yeah, it was a long day yesterday and I must've been exhausted - because my brain saw rows of "125W" in TFA's table, but looking at it today, that column is "PBP", and then there's another column with more meaningful values along the lines of what you've shared. Now I'm wondering, what's PBP? Processor Base Power, is apparently an Intel-specific term introduced with 12th generation Alder Lake chips, and it's meant to convey the thermal energy which must be dissipated when said CPUs are running at their base frequency. https://liliputing.com/pbp-vs-tdp-intel-changes-power-consumption-starting-with-12th-gen-chips/ https://liliputing.com/pbp-vs-tdp-intel-changes-power-consum... Thank you brucethemoose for helping clarify this for me!

        Yeah, its complicated. I believe the confusion is intentional on Intel's part. They want to suggest typical max power is 125W, when thats not the case at all, especially on modern motherboards that will hold boost clocks indefinitely.

I remember the strain of Intel designing up to the "thermal wall" of an architecture before a refresh. Computer shops would use the same often passive heatsinks with fan shrouds that worked with previous models, and between the north bridge and CPU would dump enough heat into the case to either cause throttling or fry the graphics accelerator after a few weeks or months. Or your computer would sound like a jet taking off every time it pulled a little load. Ridiculous wattages seem to be a historical sign that they're actively competing with AMD. I know I've got a picture of a friend cooking cup noodles with egg by setting it on their heatsink while compiling. "Why waste it.JPG"
