The two classical metrics of CPU performance are IPC (instructions per cycle) and clock speed. It was also called "NetBust," a term popular with reviewers who reflected negatively upon the processor's performance. The result of this was that the NetBurst micro architecture was often referred to as a marchitecture by various computing websites and publications during the life of the Pentium 4. In terms of product marketing, the Pentium 4's singular emphasis on clock frequency (above all else) made it a marketer's dream. Computer-savvy buyers avoided Pentium 4 PCs due to their price premium, questionable benefit, and initial restriction to Rambus' RDRAM. Tom Yager of Infoworld magazine called it "the fastest CPU - for programs that fit entirely in cache".

For example, in mathematical applications, AMD's lower-clocked Athlon (the fastest-clocked model was clocked at 1.2 GHz at the time) easily outperformed the Pentium 4, which would only catch up if software was re-compiled with SSE2 support.

The NetBurst microarchitecture consumed more power and emitted more heat than any previous Intel or AMD microarchitectures.Īs a result, the Pentium 4's introduction was met with mixed reviews: Developers disliked the Pentium 4, as it posed a new set of code optimization rules. Its main downfall was a shared unidirectional bus. But in legacy applications with many branching or x87 floating-point instructions, the Pentium 4 would merely match or run slower than its predecessor. With carefully optimized application code, the first Pentium 4s outperformed Intel's fastest Pentium III (clocked at 1.13 GHz at the time), as expected. In benchmark evaluations, the advantages of the NetBurst microarchitecture were unclear.

Intel also marketed a version of their low-end Celeron processors based on the NetBurst microarchitecture (often referred to as Celeron 4), and a high-end derivative, Xeon, intended for multi-socket servers and workstations. Intel's official launch of Intel 64 (under the name EM64T at that time) in mainstream desktop processors was the N0 stepping Prescott-2M. The E0 revision also adds eXecute Disable (XD) (Intel's name for the NX bit) to Intel 64.

Intel subsequently began selling 64-bit Pentium 4s using the "E0" revision of the Prescotts, being sold on the OEM market as the Pentium 4, model F. The first Pentium 4-branded processor to implement 64-bit was the Prescott (90 nm) (February 2004), but this feature was not enabled. Later versions introduced Hyper-Threading Technology (HTT). The Pentium 4 Willamette (180 nm) introduced SSE2, while the Prescott (90 nm) introduced SSE3. Īll Pentium 4 CPUs are based on the NetBurst microarchitecture. The production of Netburst processors was active from 2000 until May 21, 2010. The processors were shipped from Novemuntil August 8, 2008.
