ARM's US mobile division head James Bruce said in a conversation late Tuesday that the first phones and tablets using the Cortex-A15 architecture should be available by the end of 2012 or early into 2013. The much improved chip design will start out cautiously with dual-core designs before moving on to quad-core later on. The performance leap over the A9 was such that he predicted to PCWorld that phones like the Motorola Atrix were part of a larger trend towards mobile devices used for desktop-level tasks.
