Intel Pentium 4 521 2.8GHz, 800MHz FSB, 1MB Cache, 90nm, 64-Bit EM64T, XD, Socket 775 CPU Processor LGA775 w/ Hyper-Threading Technology (Retail with Fan and Heatsink, BX80547PG2800EK) (Non-Refundable) (Discontinued)

On 90 nm Process in the 775-land LGA Package and Supporting Intel® Extended Memory 64 Technology (Intel® EM64T) and Execute Disable Bit
The Intel® Pentium® 4 processor on 90 nm process in the 775-land package and the Intel® Pentium® 4 processor Extreme Edition on 90 nm process in the 775-land package are follow-ons to the Pentium 4 processor in the 478-pin package, with enhancements to the Intel NetBurst® microarchitecture. These Pentium 4 processors on 90 nm process in the 775-land package use Flip-Chip Land Grid Array (FC-LGA4) package technology, and plug into a 775-land LGA socket, referred to as the LGA775 socket. The Pentium 4 processor 660, 521, 640, and 630 on 90 nm process in the 775-land package and the Pentium 4 processor Extreme Edition on 90 nm process in the 775-land package, like their predecessor, the Pentium 4 processor in the 478-pin package, are based on the same Intel® 32-bit microarchitecture and maintain the tradition of compatibility with IA-32 software.

Intel's Execute Disable Bit functionality, first released for the Intel® Itanium® processor family in 2001, can prevent certain classes of malicious "buffer overflow" attacks when combined with a supporting operating system.

Execute Disable Bit allows the processor to classify areas in memory by where application code can execute and where it cannot. When a malicious worm attempts to insert code in the buffer, the processor disables code execution, preventing damage or worm propagation.

Please Note:
Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families.
Hyper-Threading Technology requires a computer system with an Intel® Pentium® 4 processor supporting HT Technology and a HT Technology enabled chipset, BIOS and operating system. Performance will vary depending on the specific hardware and software you use.
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.
