6.1 Overview

The Intel Xeon processor 6500 and 7500 series 4S (Expandable Processor) is the microprocessor designed specifically for servers and workstation applications. The processor features quad-core processing to maximize performance and performance/watt for data center infrastructures and highly dense deployments. The Intel Xeon processor 6500 and 7500 series also features Intel® Core™ micro-architecture and Intel® 64 architecture for flexibility in 64-bit and 32-bit applications and operating systems. The Intel Xeon processor 6500 and 7500 series supports all Streaming SIMD Extensions (including SSE2, SSE3, and SSE4) and Intel 64 instruction.

The Intel Xeon processor 6500 and 7500 series 4S (Expandable Processor) uses a 1567-pins Land Grid Array (LGA1567) package that plugs into a surface-mount socket. The M910 provides support for two or four processors.
