AMD got into the low-power server processor market this year with its new Opteron X-Series family. The Opteron X2150 is especially unique for AMD because it's based on the company's APU (accelerated processing unit) architecture, which integrates both CPU and GPU engines with a high-speed bus on a single die. The server chip consumes as little as 11 watts while running at up to 1.9GHz. The Opteron X2150 also can handle big graphics workloads, thanks to its 128 graphics cores courtesy of AMD's integrated Radeon HD 8000 graphics technology. Built on AMD's "Jaguar" 64-bit x86 core architecture, the new Opteron APU looks to challenge Intel's Atom processors in the low-power server market.
