IBM has built a working version of a new computer chip, and it says it’s the most powerful ever created. At around four times more powerful than today’s top-of-the-line technology, it should pave the way for a new generation of super-speedy computers and gadgets in the not-too-distant future.
All this power is made possible by transistors that are just 7 nanometres in size (7 billionths of a metre), created using a special silicon-germanium mixture instead of pure silicon. Today’s smallest transistors are 14nm in size, with 10nm versions on the way. Source: IBM creates the world’s most powerful computer chip
