-Efficient hardware amount of calculation per wattage (nothing to do with software);
-Clock speed based on load. I'm expecting low resource consumption when using my 3D desktop, while a neckbreaking clockspeed when doing load intensive stuff like gaming;
-My fan to rotate at constant speeds for a while, because if it doesn't do that, then I keep noticing that it runs all the freaking time.
I also expect three performance modes to block the GPU from sucking my battery dead;
-Power saving (enough for desktop usage);
-Balanced (automatic switching between power saving and performance when needed);
-Performance (always working for me at the highest possible speed);
I want my laptop to be Balanced when not below 1/7th of the battery and Power saving once it hits the 1/7th mark. My desktop should always be balanced.
Performance is for when I want my PC to be responsive at all times.

Yep, and IIRC this is pretty much what you get from the proprietary driver (which is what "comes from AMD") although I don't know if it automatically switches to a more miserly mode as the battery level drops.
In the open source driver (which "comes from the community with help from AMD") there's still a lot of work to be done.Test signature

Dynpm already does what you expect in the free driver.
Now it only needs several million lines of code to do it better.

What the driver should be able to do is:
-Recognise chip;
-Know its capabilities;
-Translate this knowledge to clocking.

While I can totaly live without accelerated video, I'm guessing it would be better for my batterylife is it was accelerated and thus having a much bigger improvement in power consumption.
