What's funny to me is how people are now jumping OFF of the Thunderbolt bandwagon and on to the Shooter... why is this funny? Because people have been making the argument FOR the Thunderbolt over the Bionic saying "dual cores drain batteries quicker" or "Android isn't even optimized for dual cores yet so it's useless technology". Which is it people... are dual cores better or not?
Yes dual-core is better. Some people have been running around proclaiming the end of all battery life, but it's not the case. The guys manufacturing these things aren't stupid.
I have a Tegra 2 device and it gets great battery life. The ARM-based CPUs are used in mobile devices because of their low power drain, which is largely a result of how efficiently they "scale". That is, when you ask the processor do a lot of work, it will "scale" up to 1Ghz, do the work, and then drop back down to say 225Mhz. Ask the processor to do a moderate level of work and it'll scale up to 580Mhz, and then back down. You get the idea.
CPU's use significantly more juice at higher clock speeds (which is why these scale in the first place), so the premise behind dual-core is this: if it takes a single CPU 30 seconds at 1Ghz to do a task, then a dual-core could do the same task in 18 seconds at 500Mhz. The dual-core uses less juice for a shorter period of time.
And as far as Android not supporting SMP (Symetric Multi-Processing), it's true. For the moment. The reason we haven't seen Gingerbread pushed out to any devices yet (or even any talk about it) is because all the manufacturers are waiting for 2.4 (still Gingerbread).
Google's working on getting SMP support in Gingerbread, I *think* because they're not ready to start dumping Honeycomb on cell phones yet and we've got dual-core cell phones hitting the shelves now. It's safe to assume that most manufacturers are going to skip 2.3 and jump straight to 2.4 when the code comes out.
All that said, my HTC Evo with a single 1Ghz CPU gets a quadrant score of about 1220, running CM7 (Gingerbread 2.3.3). My G-Tablet, on the other hand, with the Tegra 2 CPU gets a quadrant score of about 2360. And that's running VEGAn (Froyo 2.2.1).
I can't wait to see how much this thing screams when I can get 2.4 on it with full SMP support.
