3D chiplets will be the key to building the world's first one-trillion transistor GPU, says TSMC chairman Mark Liu and chief scientist H.-S. Philip Wong. The semiconductor industry is always going to want to cram more transistors into processors, but as Liu and Wong outline in a IEEE Spectrum report, AI has made this demand even more insatiable. Established companies and startups are snapping up as many GPUs as they can for the use of running AI workloads, and naturally chips with higher perform...
