One of the sad truths about mobile technology is typically this: the more processing power you have available to you, the less efficient your device will be. Fortunately, there have been plenty of ways to increase your battery life, but really, it's up to the manufacturers to make a huge gain. And the most important manufacturer to do that is the CPU/GPU manufacturer.
NVIDIA realizes this, thankfully, and has announced that its Kal-El series of quad-core processors will have a "companion core." Its purpose is to take some of the lower-level processing away from the quad-core beast to have a major, positive effect on battery life, while stlll being able to get work done.
I think this is a pretty big deal; Windows 8 might be pretty efficient, but quad-core processors are still power suckers, so having this technology available to those tablets should help battery life immensely.
What do you think about this? Is it even a quad-core processor to you anymore?[NVIDIA Mobile Blog]
