Anonymous Samsung executive denies the report of a 20% price hike on chips sold to Apple7
switch to TSMC sometime down the road. Apple and Qualcomm each allegedly offered the chip manufacturer $1 billion for the total output of 20nm chips that would be turned out by the company at a dedicated foundry. The offer was turned down as TSMC said that it wants to remain flexible for other OEMs.
Meanwhile, there is speculation that Samsung has canceled the construction of a new logic fabrication facility due to the possibility that the Korean manufacturer will lose orders from Apple for its next-generation chip. We can't say for sure that this is all based on the acrimony each side has for the other after all of the legal battles, but it wouldn't be a surprise to find out that it was a factor behind both Apple and Samsung's actions.
