Apple's latest iPhone 5 has hit the streets, but what many people don't know is that most of the phone is actually made by Samsung. Samsung fabricate the CPU and make the display and also many of the wireless chips (they used to be made by Cambridge Silicon Radio/CSR, but Samsung acquired their chip division). Apple are moving chip fabrication away from Samsung and their A7 chip will be fabricated by TSMC (or other fab plant), though they may not completely remove themselves from Samsung as they have a production line set-up for the A6. Samsung contributed both design and technology expertise to Apple's earlier CPUs but now much of this expertise has been taken in-house and Apple just require a silicon fab to actually manufacture their new CPUs. The A6 was almost entirely engineered in-house by Apple. This will be a blow to Samsung as they struggle to fill the production lines at their fabs.
