In a column published on Forbes.com, chief scientist and senior vice president of research at Nvidia, Bill Dally, has suggested that it might be time for the world to move on from the venerable Moore's Law. Drawing attention to an often overlooked aspect of the prediction where power consumption is concerned, Dally noted that Moore's Law has reached a limit in this regard, on traditional CPUs.

The continued ability to reduce power consumption is required for overall electrical power consumption to remain constant--even as each iteration of processors gain even more transistors.

However, this power scaling has ended, and Dally wrote, "... as a result, the CPU scaling predicted by Moore's Law is now dead. CPU performance no longer doubles every 18 months." Dally noted that the solution lies in taking the leap into parallel processing.  "We have reached the limit of what is possible with one or more traditional, serial central processing units, or CPUs," Dally concluded.
