Pentium 4 was a band of single-core desktop and laptop axial processing units (CPUs), alien by Intel on November 20, 20001 and alien through August 8, 2008.2 They had a 7th-generation x86 microarchitecture, alleged NetBurst, which was the company's aboriginal all-new architecture back the addition of the P6 microarchitecture of the Pentium Pro CPUs in 1995. NetBurst differed from P6 (Pentium III, II, etc.) by featuring a actual abysmal apprenticeship activity to accomplish actual aerial alarm speeds3 (up to 3.8 GHz) bound alone by TDPs extensive up to 115 W in 3.4 GHz –3.8 GHz Prescott and Prescott 2M cores.4 In 2004, the antecedent 32-bit x86 apprenticeship set of the Pentium 4 microprocessors was continued by the 64-bit x86-64 set. The achievement aberration amid a Pentium III at 1.13 GHz and a Pentium 4 at 1.3 GHz would accept been hardly noticeable. So the Pentium 4 alarm abundance bare to be about 1.15 college than a Pentium 3 to accomplish the aforementioned performance. 5
The aboriginal Pentium 4 cores, codenamed Willamette, were clocked from 1.3 GHz to 2 GHz. They were appear on November 20, 2000, application the Socket 423 system. Notable with the addition of the Pentium 4 was the 400 MT/s FSB. It absolutely operated at 100 MHz but the FSB was quad-pumped, acceptation that the best alteration amount was four times the abject alarm of the bus, so it was marketed to run at 400 MHz. The AMD Athlon's double-pumped FSB was active at 200 MT/s or 266 MT/s at that time.
Pentium 4 CPUs alien the SSE2 and, in the Prescott-based Pentium 4s, SSE3 apprenticeship sets to advance calculations, transactions, media processing, 3D graphics, and games. Later versions featured Hyper-Threading Technology (HTT), a affection to accomplish one concrete CPU assignment as two analytic CPUs. Intel additionally marketed a adaptation of their low-end Celeron processors based on the NetBurst microarchitecture (often referred to as Celeron 4), and a high-end derivative, Xeon, advised for multiprocessor servers and workstations. In 2005, the Pentium 4 was complemented by the Pentium D and Pentium Extreme Edition dual-core CPUs
