Ugh. That's as fast as a 7840U. Kraken will be a total dud with 4+4. Probably will be slightly slower in both CPU and GPU compared to Phoenix.

Should be noted this is a very thin laptop with what I suspect may be a quiet fan profile (I will look in the bios in a minute). This laptop is Macbook Air thin. I suspect the thicker laptops will boost longer.

You dont know what is the power used by his device, so that s just speculations on a vaccum, it s 100% sure that a 7840U use quite more power for this score, eventually roughly 50% more power.

Edit : It should be at barely 0.5x the power for a same score as a 7840U.

IPC uplift is 17%, core count is 1.25x, so that make about 1/(1.17 x 1.25)^2.3 = 0.42x the cores power at same perf than a 7840U.

Well it has dual fans and Asus says 28W. It could be a bit lower than that in that specific setting, but i dont believe it when its plugged in. 7840U has 13000 something at 32.5W short burst and 28W sustained in Thinkpad T14 G4 according to Notebookcheck.

I agree with you Strix Point looks to be a minor improvement in CPU performance over HawkPoint.

I agree that I don't think it's a massive performance boost, but just pointing out this probably isn't the best device to get the full picture.

I wish the Bios was better, it's very basic. No fan profiles or anything, even in advanced mode.

Dell has multiple fan profiles in their Alder Lake Latitude laptop BIOS. I remember there was silent, power optimized, turbo and balanced.
Ok. Didn't know that. I know from Acer that Fn+f is power/Fan profiles and in BIOS you can't do anything. My 5 year old Swift 5 is barely thicker than Zenbook S16 and can cool ~21-23W with single Fan, so 28W shouldn't be a problem with 2 Fans.
