Seems to me that all Intel can do at this point with their 14nm++++ is pump the Ghz and power consumption (when actually turboed to that high clock) up as far as they can.
- gsnedders 6y agoThe power consumption isn't going up quite as quickly as we'd expect; we're seeing a return to high frequencies partly because we're seeing high-end CPUs manufactured on a vastly more mature process than we typically have part.

From anandtech's coverage: https://www.anandtech.com/show/15758/intels-10th-gen-comet-lake-desktop https://www.anandtech.com/show/15758/intels-10th-gen-comet-l... "Users wanting the 10-core 5.3 GHz will need to purchase the new top Core i9-10900K processor, which has a unit price of $488, and keep it under 70 ºC to enable Intel’s new Thermal Velocity Boost. Not only that, despite the 125 W TDP listed on the box, Intel states that the turbo power recommendation is 250 W – the motherboard manufacturers we’ve spoken to have prepared for 320-350 W from their own testing, in order to maintain that top turbo for as long as possible." Power is going up and by a lot to hit that 5.3Ghz. And requires a much lower temperature to do it.
- blattimwind 6y agoKeeping a CPU under 70 °C while dissipating 300+ Watts is going to be tough even for high end custom loops. Air just isn't an option for these CPUs at all.
- gsnedders 6y agoLook at the clockspeeds and power consumption of Intel's original 14nm process. In comparison to that, the power consumption is low for a given clockspeed. That they've got the power consumption down is precisely what allows them to then increase clockspeed which then brings it back up.
