Apple starts trial of their next processor and Samsung is no longer their manufacturer.
Apple has started trial production of A6 processor which is successor to the A5 processor powering the iPad 2. A5 was a dual core processor while A6 is a custom designed quad core, high performance, lower power, 28 nanometer system-on-a-chip (SoC) processor using ARM based architecture. It is being manufactured by Taiwan Semiconductor Manufacturing Co. (TSMC) instead of Samsung.
There were some patent disputes for Galaxy Tab 10.1 in Europe and Australia, because of which Apple has stopped contract with Samsung and opted for Taiwan Semi Conductor Manufacturing Co. for their needs. Although these are still trial productions, but industry sources think that Samsung has lost its revenue stream from Apple for good and they would not be joining hands again. Commercial A6 processors will be released by second quarter next year at earliest.
