The innovation is being able to run the chips at higher temps without ruining them too quickly.

Haven't AMD CPUs been targeting a 95°C limit for 5+ years already? I'd have guessed servers could do 60°C without degrading a whole lot before switching to more power efficient hardware is available.

95˚C is the core temp, not ambient. My parent comment was probably wrong though, see https://news.ycombinator.com/item?id=48667527
