Intel® Pentium® 4 Processor 551 supporting HT Technology (1M Cache, 3.40 GHz, 800 MHz FSB)
The Intel® Pentium®4 processor on 90 nm process in the 775-land package is a follow on to the Pentium 4 processor in the 478-pin package with enhancements to the Intel NetBurst® microarchitecture. The Pentium 4 processor on 90 nm process in the 775-land package uses Flip-Chip Land Grid Array (FC-LGA4) package technology, and plugs into the 775LGA socket. The Pentium 4 processor in the 775-land package, like its predecessor, the Pentium 4 processor in the 478-pin package, is based on the same Intel 32-bit microarchitecture and maintains the tradition of compatibility with IA-32 software.
Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families.
Intel® Extended Memory 64 Technology (Intel® EM64T) requires a computer system with a processor, chipset, BIOS, operating system, 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. See www.intel.com/info/em64t for more information including details on which processors support EM64T or consult with your system vendor for more information.
Requires an Intel® Hyper-Threading Technology (Intel® HT Technology)-enabled system, check with your PC manufacturer. Performance will vary depending on the specific hardware and software used. Not available on the Intel® Core™ i5-750. For more information, including details on which processors support HT technology.
