Processors - value vs price

PROCESSOR REVIEWS TEND TO FOCUS on performance, and rightly so. We all want to see how well the latest silicon plays games, encodes media files, renders scenes, and performs various other tasks. But performance isn't the only metric that's important for CPUs. For instance, power consumption and energy efficiency are also an important piece of the puzzle, as is the actual cost of the chip. We've considered all of these things in our CPU reviews for years, but we've never before set out to quantify the value proposition—to show exactly how much bang you'll get from dropping your hard-earned bucks on a particular CPU...
