Remember how not too long ago, computer chip makers were desperate to overcome manufacturing barriers that were keeping them from making chips in the 32-nanometer class? Ha, good times, as IBM just announced they have successfully produced chips at the 5-nanometer level.
A little computer chip 101 here: the smaller you can make the transistors on a computer chip, the more you can cram into a given amount of space, increasing memory density, performance and speed. But of course, it’s not easy: we’re talking about working at molecular scales and sizes that make human hairs look like mega-structures.
IBM says their 5-nanometer design gives a 40-percent performance boost over a competitor’s 10-nanometer chips, and they can now squeeze 30 billion transistors onto a chip about the size of your fingernail. Oh, and they also say they can make the process work at the 3-nanometer level, so hey, much more to come. Story:
