No, it is not that simple. i5 and i7 are not always ordered by number. However, i9 tends to be hotter than i7.

For basic tasks, chances are great though that lower specs together with lower power allowances mean less actual power consumption. However, low power / "idle" use involves further complication because devices are, or are not, tuned to behave well under low power. Tests should tell you.

Go by specs and tests rather than only by specs!

Thanks. So, generally speaking, the higher spec laptop will use more power than the lower spec just for basic computer tasks?

Basically, i9>i7 and 3060>3050 but it varies depending on their PL1, PL2 and TDP power allowances so check these values as well.

If I use a Dell 7720 with RTX3060 and i9 processor vs RTX3050 with i7 processor but mostly for day-to-day non-gaming use,  which combination will have more power consumption and drain the battery quicker?
i.e. Which set up will allow for more extended battery usage, assuming non gaming use?

Thanks 996forever still the difference is substantial. Not only Nvidia consumes more power 130w Vs 80w it has substantially lower temperatures. I think the maximum it achieved was 70C while the R5800H surpassed 90C.

Quote from: LL on June 22, 2022, 04:35:13Interesting exercise which means the number of cores matter.

I came up with a recently discovery that puzzled me concerning temperatures and energy of CPU vs GPU calculations, Maybe notebookcheck can shed a light on it and make an article.

I have lenovo laptop with a 5800H and a RTX3060.

When i push the 5800H to the max which is about 80w power consumption like rendering Blender scene in CPU the fans are at maximum, full blast noise.

When i GPU render in Blender in Optix in RTX3060 it is at max of 125-130w but the fans are not at max and noise is consequential much less.

So the question is : why while more energy being spent in GPU than CPU needs less active cooling?

 

Heat density. The 5800H has a much smaller die size and will be much harder to cool than a larger die at the same power consumption. Nvidia GA106 die is 276mm2 vs AMD Cezanne die size of 156mm2.

The RTX 3060 may be faster than the RTX 3050, but it is operating under the same 65 W TGP meaning it doesn't need to run any warmer or require more power from the outlet to do so.
