Intel's numbering is not a measurement of higher performance. Processor numbers differentiate features
within each processor family, not across different processor families. See:
http://www.intel.com/products/processor_number/ for details.
64-bit computing on Intel® 64 architecture requires a computer system with a processor, chipset, BIOS,
operating system, device drivers and applications enabled for Intel 64 architecture. Processor will not
operate (including 32-bit operation) without an Intel 64 architecture-enabled BIOS. Performance will vary
depending on your hardware and software configurations.
Dual-Core, Quad-Core and Six-Core technologies are designed to improve performance of
multithreaded software products and hardware-aware multitasking operating systems and may require
appropriate operating system software for full benefits. Check with software provider to determine
suitability. Not all customers or software applications will necessarily benefit from use of these
technologies.
