Packageless processors; improving AI accuracy; superconductivity rules. BY: ANN STEFFORA MUTSCHLER

Demand for increasing performance is far outpacing the capability of traditional methods for performance scaling. Disruptive solutions are needed to advance beyond incremental improvements. Traditionally, processors reside inside packages to enable PCB-based integration. However, a team of researchers from the Department of Electrical and Computer Engineering from the University of California, Los Angeles along with colleagues from the Department of Electrical and Computer Engineering, University of Illinois at Urbana-Champaign argue that packages reduce the potential memory bandwidth of a processor by at least one order of magnitude, allowable thermal design power (TDP) by up to 70%, and area efficiency by a factor of 5 to 18.
