Article: GPU and CPU efficiency analysis

On the eve of so many upcoming GPU and CPU announcements it is only appropriate to take a step back and re-evaluate the status quo with a critical eye.

The computer industry is on the cusp of yet another turn of Sutherland's Wheel of Reincarnation, with the graphics processor unit (GPU) cast as the heir apparent of the floating point co-processors of days long gone. Modern GPUs are ostensibly higher performance and more power efficient than CPUs for their target workload, and many companies and media outlets claim they are leaving CPUs in the dust. Is this really the case though?

This article explores the quantitative basis for these claims, with some surprising results. Once you consider the larger die area and power consumption for modern GPUs, the efficiency advantages aren't quite as tremendous as they seem at first glance.

As always - comments and discussion are welcome.
