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.

†

Hyper-Threading Technology requires a computer system with a processor supporting Hyper-Threading Technology

and an HT Technology enabled chipset, BIOS and operating system. Performance will vary depending on the

specific hardware and software you use. See www.intel.com/info/hyperthreading/ for more information including

details on which processors support HT Technology.

Intel

Virtualization Technology requires a computer system with an enabled Intel

processor, BIOS, virtual machine

monitor (VMM) and, for some uses, certain platform software enabled for it. Functionality, performance or other

benefits will vary depending on hardware and software configurations and may require a BIOS update. Software

applications may not be compatible with all operating systems. Please check with your application vendor.

64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, operating

system, device drivers and applications enabled for Intel

64 architecture. Processors will not operate (including

32-bit operation) without an Intel 64 architecture-enabled BIOS. Performance will vary depending on your hardware

and software configurations. Consult with your system vendor for more information.

5500 based on Xeon

W5580 (D-0 stepping). Number of operating states includes all

frequency operating points, including Turbo Boost and base frequency. Idle power based on C6 idle power for

Xeon

5500, and C1E for Xeon

5300 and 5400 SKUs. C6 also requires OS support and may vary by SKU. Faster

transitions based on Package C1E exit transition latency and PLL lock time for p-state transitions.
