Mode selections

[Saltine713]

I know the 3 modes on the Prime:

Power Saving
Balanced
Performance.

I know the basics of what they do. However, what do they actually change in the performance of the tab that is noticeable? I never really noticed any difference in going from power saving to performance, even when I was already doing a bunch of multitasking.

Oh, please someone answer this, I've also tried to figure this out.

Quoted from a Cnet review:

The other selling point of Tegra 3 is improved power consumption--Nvidia claims it is up to 61 percent less than Tegra 2. In fact, the Transformer Prime comes with three power profiles--Normal, Balanced and Power saving. In Normal mode, the Tegra 3 processor runs at a top speed of 1.3GHz with all four cores active. If only a single core is being used, this goes up to 1.4GHz. Balanced mode reduces the highest frequency to 1.2GHz while Power saving brings the clock speeds even lower, especially when more cores are used (it also dims the screen slightly). For less intensive tasks such as browsing the Web or video playback, the tablet will automatically default to using a fifth, companion core, which is supposed to consume even less power.

So it still keeps all (5) cores active, just changes how they are clocked?


Also, it seems when I use a CPU monitor app, it shows really only 1 core doing most of the work most of the time, only switching to other cores when the 1st one is completely clocked out.

Is this normal?

There are 4 cores used for actual work and one that handles background processes, that's what I've read anyway. As for the cores, I have seen the same on my prime. I imagine it's set up like that so the other cores don't drain your battery as fast as all four running at the same time would.

Power Saving - 1.0Ghz
Balanced - 1.2Ghz
Performance - 1.3 Ghz (1.4 in interactive)

I use setcpu to check speeds with mine these are at each setting. There is also an app called EZOverclock which will allow you to set each one to whatever speed you want (like 1.6 Performance). Both require root

It seems the modes really don't make that much of a difference clock-wise.

There is also a kernel that will let you run at 1.8 ghz over on XDA.
