The Quad Core Xeon E5420 processor delivers impressive performance, up to 4 times that of the earlier generation single-core processors. A massive 12MB of L2 cache increases the efficiency of cache-to-core data transfers, maximizing memory to processor bandwidth and reducing latency. The 64-bit cores are designed to handle all of today’s x86 32-bit software with ease and can effortlessly migrate to 64-bit software.
You also get Intel Virtualization Technology hardware enhancements that support software-based virtualization. It works with VMware, Virtual PC and XenSource, as well as virtualization products from an increasing number of software vendors. Virtualization combined with multiple cores gives you maximum power and performance per clock cycle.
