The first CPU to use this architecture was the [[Pentium 4#Willamette|Willamette-core Pentium 4]], released on November 20, 2000 and the first of the [[Pentium 4]] CPUs; all subsequent Pentium 4 and [[Pentium D]] variants have also been based on NetBurst. In mid-2001, Intel released the ''Foster'' core, which was also based on NetBurst, thus switching the [[Xeon]] CPUs to the new architecture as well. Pentium 4-based [[Celeron]] CPUs also use the NetBurst architecture.

NetBurst was replaced with the [[Intel Core (microarchitecture)|Core microarchitecture]] based on P6, released in July 2006.
