Disclaimers
Intel's numbering is not a measurement of higher performance. Processor numbers differentiate features
within each processor family, not across different processor families. See:

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. See:

for more
information.
Quad-Core, Six-Core, and Eight-Core technologies are designed to improve performance of multithreaded
software products and hardware-aware multitasking operating systems and may require appropriate
