That’s what binning silicon gets you. You cherry pick the low leakage golden sample chips for laptop, and high leakage (sometimes imperfect) chips for desktop where the energy waste & extra energy needed to stabilize imperfect structures is not a deal breaker.
Another contributor could also be that the ~+300 MHz multi-core of the desktop variant is beyond the efficient range of its voltage/frequency curve, whereas the laptop variant backs down the curve to a point where minimal performance is lost but energy efficiency increases dramatically.

Well, whilst this is impressive performance for a mobile CPU, like nearly all budget/mid level gaming laptops, they are nerfed by either the GPU or bad Mem/Storage configurations. (I'm assuming it's a gaming laptop given the pic)

Still, it's a great CPU by the looks of things.

but... but... if they can get that level of performance from the laptop variant at a lower power threshold...

and... if this really just comes down to yield curves...

Then why haven't we seen any of this power efficiency and performance anywhere else?

I don't believe the performance of the laptop variant is actually anywhere near a desktop variant in real world usage or else we'd see desktops running similar schemes. Not everyone can afford unlimited/huge amounts of electricity, so desktop CPUs that can run at the power and levels of laptops while delivering near desktop performance would be huge for those that can't afford high electricity bills.

But then again, as an American, it's hard to imagine US corporate entities caring about anyone else but the wealthy and well-to-do. Who cares if you can't afford the electricity to power this season's latest CPU, you probably couldn't afford it anyway? /cynically exhausted

I want the 14700 cpu... on the h670 board

Well like I said, only low leakage golden samples can work in a laptop setting with power/temperature limitations and battery life are concerned. That leaves the leaky chips for desktop, so even if they do set the desktop parts to laptop frequencies, it will require more voltage and wattage to achieve due to leak losses (Intel could easily rob the laptop segment of low leakage chips, but why would they when they charge more for laptop variants). Next you have Intel’s pride pushing frequencies beyond optimal so they can get a win against AMD.

But to your point, yes, I’m sure the laptop parts can reach similar levels to desktop for short periods before the heatsink becomes saturated in heat, then it must limit frequency to maintain heat exchange equilibrium.
