Arm: Performance Per Watt is a New Performance Metric


Arm has today posted a new article to its Arm Blueprint blog, making claims that the computing paradigm is changing as we know it. More specifically, the company is calling performance per watt a new metric of improvement. Arm’s Rob Aitken, Fellow & Director of Technology, has written a post giving a retrospective look at the industry and where it is going. 

Starting from the early beginning, we have seen a massive increase in one area: transistor density. According to an observation, called Moore’s Law, that transistor count doubles every two years, we are seeing continued improvement in the performance of our devices. That was a true observation, until the past few years where we hit a roadblock.
