Intel Pentium 4 Logo – The Intel Pentium 4 is a microprocessor of the seventh x86 -generation. The first Pentium 4, code-named Willamette ran at clock speeds of 1.4 and 1.5 GHz , and came in November 2000 on the market. The Pentium 4 with the new NetBurst architecture had compared to the older P6 design of the Pentium III in terms of integer and floating point performance in only minor improvements. Instead, they had focused on two things: high clock frequencies, have been aggressively promoted, and SSE performance.
The Pentium 4 is available, as has occurred in the older Pentium families, even in a low-cost version called Celeron , and in a version called Xeon , the symmetric multi-processing support. For better delineation of the Celeron versions of the Pentium II and Pentium III, Pentium 4, derived from the variant is often referred to as Celeron fourth Newer models with Prescott core are called Celeron D sold. As a special feature Intel still had a Pentium 4 Extreme Edition in the program, as the high-end CPU with AMD’s Athlon 64 FX is positioned. The developed based on the NetBurst architecture, dual-core CPUs under the name Pentium D or Pentium Extreme Edition sold.
