And while you normally need to crank clock speed to see better performance, Qualcomm decided to do the opposite.

“We knew we couldn’t just keep increasing frequency,” explained Heape. “You can’t go into the multi-universe of frequencies and still be thermally viable. So now instead of processing …read more
