Not to be confused with switching iPhones and iPads to Intel-powered chipsets, Apple is rumored to have been in discussions to have their existing iOS device chipsets manufactured by Intel's industry leading foundries. Noel Randewich and Nadia Damouni of Reuters report:
Adding to the ever-growing iPad 3 rumor mill, a new photo has surfaced on the WeiPhone forums showing a system-on-a-chip nestled onto a prototype logic board, carrying a previously unheard of "A5X". The A5X chip also includes a date code of "1146", which would peg production at or around November 14th-20th of 2011.
Apple Insider reports that Samsung has a 45 nanometer, 1GHz ARM processor, code-named "Hummingbird" on the horizon.
It uses the same Cortex A8 architecture as the current iPhone 3GS (which runs at a clocked-down 600MHz) but due to the smaller size, is said to not consumer any more power or generate any more heat than the current 833MHz generation.
