The power draw on these compared to AMD feels absolutely bizarre - in an age where we're supposed to be trying to conserve resources, it feels ridiculously wasteful to burst up to 430W [1] for minor gains. That's over 200W more than the approximately equivalent AMD chip (the 7950X), for practically no performance over it.

On the other hand, I believe idle power usage is generally lower on Intel parts than on AMD parts, which is usually something that is less methodically reviewed and generally far more important than this peak power shenanigans.

You're right, this is much harder to find reputable numbers for :/

https://www.guru3d.com/review/intel-core-i7-13700k-review/pa... is the closest I can find, and it's whole PC power draw - and it has them all fairly even. I suspect it's dominated by other components like GPU, though?

Don’t worry, they are committed to sustainability.

The picture on that link clearly shows how you can heat up greenhouses by running 14th gen. CPUs at modest speeds.

On a more serious note, kudos to them if these numbers are true. That’s a decent amount of renewables and waste reduction at such an industrial scale.

And the 7950X is still very turbo happy for minimal gains.

The 7800X3D is a good example of what it would be like capped to "just" 5GHz and a lower all-core TDP.

These feel like the last generation P4s back in the day. Intel had better have another Conroe in the wings for the next generation.

If you consider that winter is coming, the 430W heater under the desk isn't a bad idea...

If only there were some kind of information pump that could convert heat into information and vice versa. Then you could decide which calculations to run depending on whether you want to cool or heat your room. ;-)

Conversely, in climates that don't experience much winter, I'm wondering how feasible it is to either duct the exhaust air directly outside or run long hoses on my radiator and put it outside. Get that hot air out of here!

(I know it's a joke, but...) Only if your alternative heating was through electric resistive heating. Natural gas heaters and electric heat pumps will both provide 430W heat with less than 430W electricity usage.

That is crazy. What kind of cpu cooler do you need for that? Is water cooling a requirement with these >400W figures?

Yes, people test the '900K with 360 mm AIO coolers.
