In the past few days, the smaller A5 chip used in the latest Apple TV has been the foot pad for discussion. Many people want to understand why Apple has reduced the size of the A5 chip to half. Yesterday experts from Chiworks said that the new A5 chip is still from Samsung and uses a 32-nanometer process, but Apple may have adopted a completely new design.
Now Chipworks has released the latest pictures of A5, showing that the small size A5 chip actually contains only one ARM CPU core. Last year the third generation of Apple TV was released, and Apple listed it as a single-core A5 device. However, the previous old A5 chip only covered one of the CPU cores, while the new design only contained one CPU core. Of course, the same as the previous generation A5 chip, the new A5 still has dual-core GPU.
Chipworks company Dick James said that in order to achieve a 50% reduction in size, Apple has other technologies, but it is not yet sure how Apple will reduce the size. It may be that the new A5 chip uses a brand new analog circuit, using optimized resistors, capacitors and inductors to achieve. It is unclear why Apple has redesigned the A5 chip for Apple TV, because Apple TV shipments are not large. Of course, Apple may also use the new A5 chip in other products. Of course, flagship products do not seem to use this single-core CPU chip.
