Sony has ruled out releasing a quad-core smartphone this year due to the fact that they would be battery vampires.
Instead Sony said it will adopt the ARM Cortex A15 dual-core design later this year.
The announcement is a slap in the face with a wet fish for Nvidia's Tegra 3 and LG Optimus 4X HD, then came the HTC One X, the ZTE Era and Huawei's Ascend D Quad. Everyone expects Samsung's quad-core Samsung Galaxy S III to be out soon too.
But Nokia and Sony have both indicated that power concerns make the technology useless.
In a conversation with CNET Asia , Sony made it quite clear it wouldn't be releasing a quad-core smartphone until 2013 at the earliest. It thinks the idea of a quad-core phone has legs, but it does not make sense to switch yet.
It might have a point. There have been few quad-cores tested and no one knows if batteries can handle the processors or the big screens that often go with them.
It seems to us that Sony could be the smart by using the Cortex A15 architecture during the second half of 2012 because it provides a better power to performance ratio.
The first devices to use the ARM Cortex A15 design will appear toward the end of the year.
Texas Instruments has released a video showing the performance differences between it running at 800MHz and a 1.3GHz quad-core Nvidia Tegra 3.
