Leo Kelion, BBC News:
The “five nanometre process” involved refers to the fact that the chip’s transistors have been shrunk down – the tiny on-off switches are now only about 25 atoms wide – allowing billions more to be packed in.
Moving to smaller transistors helps because they use less power than larger ones, meaning they can be run more quickly. On this basis, TSMC has said that its 5nm chips deliver a 15% speed boost over the last 7nm generation while using the same power.
Apple has already claimed its A14 chip will do machine learning tasks “up to 10 times faster” than the A13.
All of this is important, important across the product line, including the up and coming Apple silicon powered Mac, said to ship by the end of the year.
What makes this article so interesting is that it gets into the details on how the 5nm process was achieved, using a technique called “extreme ultraviolet (EUV) lithography”. Great read.
