looking to maybe pickup a new framework mainboard. which one of these would run coolest if i use on my lap a lot?

The Intel Core Ultra Series 1
The Amd Ryzen AI 300 Series
The Amd Ryzen 7040 Series

All I can say is definitely not the 7040 series, it can get uncomfortably hot.

Thanks. I have the intel 11th gen (or w/e the first framework laptop was shipped with) and it also gets pretty darn hot for literally having 1 tab open in my browser.

This is the power consumption comparison on notebookcheck. In computing electric energy is converted to heat so this can be indicative

The Intel Core Ultra would likely be the lowest heat producer. Additionally, you can throttle down the processor so it does not generate nearly as much heat. In a regular BIOS if you turned off TurboBoost that would help a lot as it keeps the processor from clocking up really high which of course generates lots of heat. If you neutered the processor to just two cores that would really cut back on the overall heat and should still allow decent performance.

Traditionally the newer the processor (i.e. with the smallest manufacturing technology node it was fabricated on) would generate the least amount of heat. The AMD AI processors while using the latest nodes though are little powerhouses of performance and they can crank up the heat pretty good.

Keep in mind your meaty legs :meat_on_bone: are likely one of the worst surfaces to rest a laptop on for heat disappation, the less air getting :wind_face: under the machine the hotter it is going to get vs. it sitting on a hard flat surface.

Years ago I had a little plastic tray? that had two tiny little fans in it that blew on the underside of the laptop with a USB-A cable. The fans did very little but just giving the machine the separation from my legs made a huge difference. :grinning:

I have a core ultra 7 and the heat is generally not bad, 40-60C is the normal range I see under my normal usage. I also run on the highest performance setting as I like the having all the power available to me. If I put a heavy load on it, it will heat up and peak ~100C but will drop back into the 70’-80’s C range, but that is likely with any CPU you choose to go with.
