Apple (NASDAQ:AAPL) has countless reasons to shift its chip manufacturing business away from Samsung. The South Korean conglomerate has used its supplier relationship with the Mac maker to compete more aggressively. To that end, it seems inevitable that Apple will transition to another foundry partner, although that's much easier said than done, since Apple and Samsung have collaborated deeply on chip production for many years.

Reports of a possible partnership with Taiwan Semiconductor (NYSE:TSM) have persisted for years on end but has gained legs in recent months, following reports from reputable news outlets. That could potentially be a big win for Taiwan Semiconductor, as Apple's foundry business was estimated at $5 billion last year.

However, Apple may have to make this transition gradually, and Samsung may still be onboard to produce 30% to 40% of the next-generation A8 chips, while Taiwan Semiconductor could get the contract for the remaining 60% to 70%. The A8 chips would likely be due out with the iPhone 6 next year.
