The Intel® E8501 chipset contains higher performance and more scalability than the prior generation Intel® Xeon® processor family. The Intel E8501 chipset enables performance gains on Intel's four-way MP platform of up to 60% over the previous generation, making the platform well-suited to running demanding, multi-threaded applications, such as databases, financial services and supply-chain management.

The chipset is designed for longevity-architected for the Intel® Xeon® processor 7000Δ sequence, yet also compatible with Intel® single-core processors-for an enhanced lifespan and for lowering Total Cost of Ownership (TCO). The chipset's ability to support 64-bit as well as 32-bit applications lets you leverage your investment even further. It also offers increased bandwidth, and greater flexibility, manageability, and I/O integration than previous-generation MP chipsets.

 Product and Performance Data 

Δ Intel® processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See www.intel.com/products/processor_number/ for details.

◊ 64-bit Intel® Xeon® processors with Intel® EM64T require a computer system with a processor, chipset, BIOS, OS, device drivers and applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation) without an Intel EM64T-enabled BIOS. Performance will vary depending on your hardware and software configurations. Intel EM64T-enabled OS, BIOS, device drivers and applications may not be available. Check with your vendor for more information.
