Apple is trying to remove all Samsung dependences. TSMC is supposed to manufacture the lion share of CPUs for the next iPhone.
A new iPhone is expected to be introduced this fall. The CPUs for the new iPhone 5S are not coming from Samsung anymore says a report in Digitimes. Apple is said to shift CPU production completely to TSMC away from Samsung. Apple and Samsung grew apart through the patent lawsuits.
Samsung will though also make CPUs for the next iPhone. The report is not quite clear on how big the share of Samsung will still be for the new iPhone.
