Quad-Core Mobile Chips Wasted On Mobiles? 336

An anonymous reader writes "Dual-core smartphones have only just hit the market, but mobile chipmakers Nvidia and Qualcomm are already turning their attention to quad-core chips. While it looks certain that tablets will be the first quad-core mobile devices in the market, chipmakers reckon they'll land in smartphones too. But do smartphones need quad-core chips? There's surely only so much multitasking a smartphone user can do. I'm interested to hear what smartphone apps/features/functions — if any — Slashdot readers reckon quad-core chips would enable"

    For argument sake, when it comes to battery, a single core may be better, if something is perfectly multi-threaded, there is still overhead of managing the threads, this overhead will translate directly to more power being sucked from the battery. So a single core may take longer, but the overall energy will be lower as there won't be any overhead to manage the threads.

    For arguments sake, when it comes to battery, quad core is a lot better, because power grows with the square of speed, so quad core can run at a quarter of the speed for a total power reduction of a factor 4. Overhead for managing multiple threads is negligible.
