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.
Quad-Core Processing with 12MB L2 Cache The Intel Xeon E5420 processor features four complete processor cores in one physical package. Significant performance headroom, especially for multi-threaded applications, helps boost system utilization through virtualization and application responsiveness. Its 12MB (2 x 6MB) L2 cache increases efficiency of L2 cache-to-processor data transfer, maximizes main memory to processor bandwidth and reduces latency.
Supports Intel Virtualization Technology (Intel VT) With Intel VT, one hardware platform functions as multiple “virtual” platforms. For business, Intel VT offers improved manageability, limiting downtime and maintaining worker productivity by isolating computing activities into separate partitions. In the home, Intel VT allows creating unique user environments for multiple family members using the same platform simultaneously.
Intel Extended Memory 64 Technology (Intel EM64T) Intel EM64T enhances next-generation IA-32 platforms with 64-bit addressability and related instructions, allowing flexibility for both 64-bit and 32-bit applications and operating systems.
Execute Disable Bit (EDB) Intel's Execute Disable Bit function can prevent certain classes of malicious "buffer overflow" attacks when combined with a supporting operating system. Execute Disable Bit allows the processor to classify areas in memory where application code can execute and where it cannot. When a malicious worm attempts to insert code in the buffer, the processor disables code execution, preventing damage or worm propagation.
Enhanced Intel SpeedStep Technology (EIST) EIST allows the system to dynamically adjust processor voltage and core frequency to decrease average power consumption and average heat production. Combined with existing power saving features, EIST may provide an excellent balance between providing power when you need it and conserving power when you don’t.
