As Moore's Law begins to break down, chip designers are turning to new techniques to squeeze more performance out of processors.

Chipmaking has never been easy. But for much of the last 50 years, the recipe was relatively straightforward: shrink the transistors at a steady pace, and use the increased density to either boost performance (and reduce power) or add new features. Scaling hasn't stopped (yet), but it is taking significantly longer to get to each new node, and costs are increasing, while the payback in performance and power are diminishing.

As a result, chip companies are looking for new ways to deliver more bang for the buck through increased parallelization (more cores), better power management, more memory capacity and bandwidth, faster interconnects and the use of off-chip accelerators. (I recently wrote about accelerators designed specifically for computer vision.) All of these trends have been on display in the recent processor announcements...
