so why didn't they just make one of the 4 cores be able to run at lower power while the other 3 are "off" (they aren't actually off since you can't have part of a die be 100% off)?

The fifth core is a crutch, if they could have got the high performance cores to run with less power they could have used one of those instead of wasting die space and power on a fifth core, they would have done that.

Sorry, no offense, but I've done a lot of research on this, and have been following the kal-El articles for some time (now the tegra 3). The core is an identical Cortex A-9 core, just clocked to lower speeds. I'm just waiting/looking forward to some comparisons. Here are some articles and links to help OCN members understand tegra 3 a little better:
First Tegra 3 'Kal-El' Android tablet coming from ZTE
Eric Brown | 2011-09-29
Quote:
The Tegra 3's fifth core is identical to the other four Cortex-A9 cores, but is clocked to a maximum of 500MHz instead of up to 1.5GHz. More importantly, it's designed to execute tasks at low frequency for active standby mode, including music and even video playback, according to Nvidia. The result is said to be a lesser drain on overall battery life.
Nvidia Tegra 3 official: a 1.3GHz quad-core chip with five times the performance of Tegra 2
Vlad Savovon | November 9, 2011
Quote:
Tegra 3 promises to quintuple the performance of Tegra 2 with its four-core Cortex A9 arrangement while also tripling its graphical capabilities with a new 12-core graphics processor. That's a great deal of power for when you need it, but Nvidia has also added a fifth, low-power "companion core," whose role will be to keep things running during standby and other low-intensity modes. That core reaches a maximum speed of 500MHz and can take care of lightweight tasks like audio streaming and some forms of video playback. Anything more demanding than that will kick in the first of the more powerful cores, which can run at speeds of up to 1.4GHz by itself, with dual-core and quad-core modes, each topping out at 1.3GHz, kicking in depending on workload.

contradicts what i thought about it being a lesser core altogether, but supports that it is lesser in that it clocks to .5 GHz

neither of us are cpu designers, the guys who made these have their reasons.

All I know is I am getting it. I have 2 tablets now (one is a G Tablet Tegra 2 and the other is an HP Touchpad) and a Kindle DX. So I will be getting rid of the two tablets and replace it with the Transformer prime.

I bet they used low-leakage transistors in the fifth core to lower power consumption and high performance transistors in the other four.
Edit: For a little reading see here. They are using a low-leakage low power process for the fifth core.

yes, because for whatever reason they couldn't get the four cores to do what they needed, so they added a fifth. I'm not just talking crap here.

so the only alternative is even worse, therefore it is not a crutch at all.

The fifth core is a crutch, if they could have got the high performance cores to run with less power they could have used one of those instead of wasting die space and power on a fifth core, they would have done that.

Because then it would be a "Tri-core", with a "4th" low power core to run the apps/video/webpages while the "3 cores" shut down...

Not only does Quad-core sound better, it is also 25% more powerful then your suggestion...

IT is a crutch

It would be a crutch to include the feature to underclock the power and speed of 1 core, just for idling, when adding a 5th core is clearly doable.
