I second that!
it was really disappointing to learn the Galaxy S4 will not come with this bad boy!

Does instantly switching between CPUs waste battery? Seems like turning a whole CPU on then off is inefficient...

The cores not in use don't completely turn off, they just run idle, not really doing any work so they use almost no power; but they're ready to ramp up when needed.
Otherwise, yes, turning them completely on or off would be very inefficient.

The one part of big.LITLLE i.e either four A15 cores or four A7 cores are turned off at one moment, and they are switched if needed.
All eight cores can be turned on through drivers but that would be pointless.

Computing has long been working like this, if you monitored your computer CPU you'd also see it switching between clocks, modes, cores. It's all one CPU divided to 4 A7 and 4 A15 cores, so it's always on, but only draining power of the actual cores in use, hence the power efficiency.

I'm still curious about what GPU they chose. A lot of sites report the PowerVR SGX544MP3, but it was never really confirmed, at least to my knowledge.
Is it the SGX544MP3? Mali-T678? SGX554MPx?

You mean for future Octa-core devices? No rumors on that one so far other than the SIV not being one. They are only demonstrating a pre-recorded video here so the Exynos5O it's still probably in pre-alpha stage.

Anandtech said the Exynos 5 Octa would use PowerVR graphics, SGX544MP3 specifically, but it was never confirmed.

Sorry, but they confirmed in a latter post, original one is
The confirmation is in:

Ah, thanks, I never saw the confirmation post. Kind of a bummer, I wanted to see what the Mali-T678 could do and how it stacks up against the SGX554MP4. The SGX544MP3 is very capable I'm sure, but I wanted to see a second gen Mali-600 in action.

It's just reference hardware to demo it in.

Cant hide my excitement seeing Octa-core working at least, hopefully it'll come in GSIV, Please Samsung surprise everyone!
