Turbo boost stepping occurs in 100MHz increments. Processors that donot have turbo functionality are denoted as N/A.Turbo [all core,1C]Ex. 2.9 GHz [4,9] turbo is 8C turbo to 3.3, 1C turbo to 3.8When ordering two processors, the second processor must be the same as the first. Intel processornumbers are not a measurement of higher performance. Processor numbers differentiate featureswithin each processor family, not across different processor families. See: number/ for details.Quad-Core, Six-Core, Eight-Core , Ten-Core and Twelve-Core technologies are designed to improveperformance of multithreaded software products and hardware-aware multitasking operating systemsand may require appropriate operating system software for full benefits; check with software providerto determine suitability; Not all customers or software applications will necessarily benefit from use ofthese technologies.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. Processors willnot operate (including 32-bit operation) without an Intel 64 architecture-enabled BIOS. Performancewill vary depending on your hardware and software configurations.
