Pentium 4 2.40A – Prescott Intel Pentium 4 640 die shot. On February 1, 2004, Intel introduced a new core codenamed Prescott. The core used the 90 nm process for the first time, which one analyst described as "a major reworking of the Pentium 4's microarchitecture." [30] Despite this overhaul, the performance gains were inconsistent. Some ...
The Pentium 4 was a seventh-generation CPU from Intel targeted at the consumer and enterprise markets. It is based on the NetBurst microarchitecture. Desktop processors
[13]: 6 During development of the Pentium 4, microcode accounted for 14% of processor bugs versus 30% of processor bugs during development of the Pentium Pro. [15]: 35 The Intel Core microarchitecture introduced in 2006 added "macro-operations fusion" for some common pairs of instructions including comparison followed by a jump. [16]
The Pentium (also referred to as the i586 or P5 Pentium) is a microprocessor introduced by Intel on March 22, 1993. It is the first CPU using the Pentium brand . [ 3 ] [ 4 ] Considered the fifth generation in the x86 (8086) compatible line of processors, [ 5 ] succeeding the i486 , its implementation and microarchitecture was internally called P5 .
Pentium M: updated version of Pentium III's P6 microarchitecture designed from the ground up for mobile computing and first x86 to support micro-op fusion and smart cache. Enhanced Pentium M : updated, dual core version of the Pentium M microarchitecture used in the first Intel Core microprocessors, first x86 to have shadow register ...
Tejas and Jayhawk were to make several improvements on the Pentium 4's NetBurst microarchitecture. Tejas was originally to be built on a 90 nm process, later moving to a 65 nm process. The 90 nm version of the processor was reported to have 1 MB L2 cache , while the 65 nm chip would increase the cache to 2 MB.
Intel had NetBurst-based successors in development called Tejas and Jayhawk with between 40 and 50 pipeline stages, but ultimately decided to replace NetBurst with the Core microarchitecture, [8] [9] released in July 2006; these successors were more directly derived from the Pentium Pro (P6 microarchitecture).
First implementation of the Core microarchitecture, sold as Core 2 Duo, Xeon, Pentium Dual-Core, and Celeron. Most Conroes are dual-core, although some single-core versions were also produced. Successor to both Yonah, of Pentium M lineage, and to Cedar Mill, the final generation of the NetBurst microarchitecture. 65 nm.
