ARM on Tuesday rolled out a unique variant on the Cortex-A15 designed to bring the next-generation chip to shelves faster and with less power use. A new hard macro variant that has fixed specifications, including quad cores clocked at 2GHz based on a 28 nanometer TSMC-made (Taiwan Semiconductor Manufacturing Company) design, instead of the "soft core" that lets firms heavily customize an ARM design to their own ends. In return, however, it's both faster to implement and uses the same power as the earlier Cortex-A9.
