Apple has opted to comment on unscientific and unrealistic test results floating around that purport to show serious differences between iPhone 6s model phones using chips made by Samsung versus those made by Taiwan Semiconductor Manufacturing Company (TSMC). Apple, which uses both companies to make its A9 processor that powers both the 6s and 6s Plus, says that there is very little real-world difference between the two chips, which are slightly different sizes depending on manufacturer.
