The tiny chips making your phone 10x faster

Every phone has a 'chip' — a super-tiny slice of silicon covered in millions of even tinier switches called transistors. Engineers keep finding ways to shrink these switches, and the new 2nm chip from TSMC packs about 30 BILLION transistors into a space the size of a jellybean. That means your next phone can play way better games, understand your voice faster, and last twice as long on a single charge. The trick? Instead of laying transistors flat, engineers now stack them up in tiny 3D skyscrapers.
