Rumours emerging from Taiwan hint at different system on chips for the Apple iPhone 5 and the iPad 2 with the production of the parts being outsourced to Taiwan Semiconductor Manufacturing Company (TSMC).
Taiwan online news outlet, Digitimes, says that Apple will be moving away from Samsung because it fears the latter, one of its biggest competitors in the smartphone market, may get insider information about its next generation A5 processor.
Digitimes also says that the iPad 2 will have an enhanced version of the A4 while the A5 will be an ARM Cortex A9-based processor.
The fact that the Samsung Orion, the successor to the Hummingbird SoC used in the Galaxy Tab and the Galaxy S, uses ARM's Mali graphics solution rather than the Apple-backed PowerVR technology from Imagination technologies was a clear sign that Samsung and Apple may have taken separate routes mid 2010.
The A5 is expected to be a dual core ARM Cortex A9 clocked at 1GHz and should deliver around three times the performance of the A4.
