The AMD Fusion family of Accelerated Processing Units (APUs) not only adds another acronym to the computer lexicon, but ushers is what AMD says is a significant shift in processor architecture and capabilities. Many of the improvements stem from eliminating the chip-to-chip linkage that adds latency to memory operations and consumes power — moving electrons across a chip takes less energy than moving these same electrons between two chips. The co-location of all key elements on one chip also allows a holistic approach to power management of the APU. Various parts of the chip can be powered up or down depending on workloads.
