Processor
Based on Intel's next-generation Core micro-architecture, the two 2.66 GHz 64-bit dual-core Intel Xeon processors combine both high performance and power efficiency. Augmenting the speed delivered by the processors, the system architecture features 1.33 GHz dual independent front-side buses that maximize the performance of the dual-core, dual-processor system and deliver maximum processor bandwidth of up to 21.3 GB/s. It also offers an enhanced SSE3 vector engine. Capable of delivering 128-bit vector computations in a single cycle, the SSE3 vector engine accelerates data manipulation by simultaneously applying a single instruction to multiple data--ideal for transforming large sets of data, such as applying a filter to an image or rendering a video effect.
