>I reran and updated the Cinebench scores again, with the laptop fresh from a cold boot up. In Cinebench R23, the CPU starts at 50W and ends up around 35W for the best-effort run. For the 10 min loop, it starts at 50W and then gradually drops and stabilizes at around 28W (after about 5-6 minutes it gets to 28W).
>
>Keep in mind it will perform differently once the heat builds-up inside, after running other sustained loads. That means it will drop in power more aggressively and quicker, and thus score lower.
>
>I'm also running the Cinebench/Blender stress logs again and will have them updated in the next hours.

>(Bios version) 201: CineBench R23: CPU 12357 pts (best run), CPU 11342 pts (10 min loop test), CPU Single Core 1751 pts (best run);
>
>(Bios version) 203: CineBench R23: CPU 13873 pts (best run), CPU 12132 pts (10 min loop test), CPU Single Core 1761 pts (best run);

>Yes, 3dmark, Uniengine are on BIOS 203. Everything else except for games and Cinebench R24 are on BIOS 203. Still updating those.
