    The problem with battery technology is no one wants to pay for it. We have the resources over hear to build, not necessarily better batteries, but hold them to tighter tolerances which in turn make them better. China pumps out thousands and could care less. Look at this forum and see how battery life differs

    As far as jerkwad's argument goes, he has good logic if chipset technology worked like an engine, but it doesn't. This new GPU likely won't require that much more power than current GPU tech. The reason for this is that it's improved performance does not happen because it is operating at higher frequencies, which would require more energy. The reason the chip is so much faster is because they can squeeze more transistors in a smaller space than the previous generations. While it will still require a bit more power to push electrons through all of those extra transistors, the efficiency is not diminished that much, and in fact if they use more advanced data routing methods and other tweaks, the efficiency of this new chip will likely be about the same as current chips. Even if it is a little worse, it won't be dramatically different, and their ability to turn off unneeded cores will enhance things even further.

    The better analogy for this chip is it is like a 4 cylinder engine with a turbo added on. You still get good fuel efficiency yet you also get a huge boost in horsepower.

    Your argument that they need to work on better batteries is absolutely valid regardless. One good thing about chip technology moving at such a rapid pace is that with the newer super-computers we can now work out calculations that would not have been possible before. This in turn will help us figure out new ways to improve batteries!

Thanks for adding positive substance to the discussion :-)
    4 cylinder with turbo is a good analogy but perhaps a better analogy is a 12 cylinder engine with multi-displacement technology, where it can shut down 4 or even 8 cylinders when cruising, using 4 cylinders on a straightaway on a limited access highway such as a turnpike, running at 1900 rpm and doing 70 mph, but if you want to pass, you press the pedal and it kicks in 4 more cylinders to give you 8 cylinder acceleration and torque...or when pulling a load like a trailer and going up hill when it pulls out all the stops and runs on 12 cylinders for the massive torque and horsepower that those 12 cylinders give.

    I have a Dodge Durango with a 5.7 Liter Hemi 8 cylinder Multi-Displacement engine and it does 1/2 of the above, shutting down 4 of the 8 cylinders when the throttle is closed or at steady speeds. It''s pretty neat as I am able to hear it and watch the tachometer drop from about 2,250 RPMs to about 1,900 RPMs and settle into a cruising speed. Mine has a "towing" button on the shift lever that turns off the Multi-Displacement - essentially bypassing it and keeping it running on all 8 cylinders, so the additional load while towing doesn't cause it to toggle repeatedly between 4 and 8 cylinders.

    The added benefit from a "multi-displacement" processor is that unlike an engine which still has all the additional friction and overhead to move all that additional steel, valves and pistons even when the cylinders are shut down, the processor's deactivated cores will consume nearly NO power during their standby periods. Also unlike an engine which has to take time to rev up, the additional cores on the processor can jump in at "full throttle" in micro-seconds, provide just the boost needed and then shut down again in less time than the human mind can detect.

    Divide and conquer!!

    As long as we are throwing analogies around, a Brayton cycle motor with reheat would fit in well.

    Exciting stuff. If you're talking a 1.5ghz single-threaded chip, 60X is equivalent to a quad-core chip with 8 threads running at 7.5ghz! Although I've always wondered if smartphone cpu speeds are equivalent to laptops. Nevertheless, that would be enough power for everything I run (provided we get the ram up to 8+ gigs). Would be nice not to have to lug around a laptop, but maybe a tablet and keyboard that I could take advantage of a larger screen and extended battery life.

    And then as far as being a laptop replacement, if you really have to use all the horses you probably would be plugged into a power source, anyway. That kind of power in a padphone-type configuration could dominate.
