Data center metric dividing total facility energy by the energy delivered to computing equipment; 1.0 is the theoretical floor.
Researchers say software is the easiest fix for AI data-center power limits, citing a training optimiser that cut energy up to 30% on unchanged hardware. With average PUE flat for six years, the remaining gains are in the servers, which draw about 60% of a facility's power.

The grid-interactive stack unveiled in Shenzhen pairs a 1,280 kVA UPS cabinet and grid-forming storage with a thermal unit built for Ascend servers. Huawei wants buyers judging it on tokens per watt in place of PUE.

The two companies say the collaboration covers custom AWS inference silicon and optical connectivity up to 1.6T. The firmest number in it is the $161.26 exercise price on Amazon's warrants for 25 million Qualcomm shares.
