Priyanka Raina: How computer chips get speedier through specialization

For decades, the general-purpose central processing unit—the CPU—has been the workhorse of the computer industry. It could handle any task—literally—even if most of those capabilities were unnecessary.

This model was all well and good as chips grew smaller, faster and more efficient by the day, but less so as the pace of progress has slowed, says Professor Priyanka Raina, an expert in chip design. Priyanka says that to keep chips on their ever-improving trajectory, chip makers have shifted focus to chips that do specific tasks very well. The graphics processing unit (GPU), which handles the intense mathematics necessary for video and gaming graphics, is a perfect example.

Soon, there’ll be a faster, more efficient chip for every task, but it’ll take industry-wide cooperation to get there, as Priyanka tells listeners to this episode of Stanford Engineering’s The Future of Everything podcast with host Russ AltmanListen and subscribe here.
