The Prescott was a major architectural revision. Later revisions were the first to feature Intel's x86-64 architecture, enhanced branch prediction and trace cache, and eventually support was added for the NX (No eXecute) bit to implement executable-space protection.
Intel's official launch of Intel 64 (under the name EM64T at that time) in mainstream desktop processors was the N0 stepping Prescott-2M. 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 ...
Intel also released a dual-core processor based on the NetBurst microarchitecture branded Pentium D. The first Pentium D core was codenamed Smithfield, which is actually two Prescott cores in a single die, and later Presler, which consists of two Cedar Mill cores on two separate dies (Cedar Mill being the 65 nm die-shrink of Prescott).
Intel Family 15 Model 4; All models support: MMX, SSE, SSE2, SSE3, Hyper-threading, Intel 64, XD bit (an NX bit implementation) Intel VT-x supported by: 6x2 e.g. Model 662 and 672; Enhanced Intel SpeedStep Technology (EIST) supported by: all except 620. Transistors: 169 million; Die size: 135 mm 2; Steppings: N0, R0
SSE3, Streaming SIMD Extensions 3, also known by its Intel code name Prescott New Instructions (PNI), [1] is the third iteration of the SSE instruction set for the IA-32 (x86) architecture. Intel introduced SSE3 in early 2004 with the Prescott revision of their Pentium 4 CPU. [ 1 ]
The Prescott-256 Celeron D was manufactured for Socket 478 and LGA 775, with 3x0 and 3x5 designations from 310 through to 355 at clock speeds of 2.13 GHz to 3.33 GHz. The Intel Celeron D processor works with the Intel 845 and 865 chipset families. The D suffix actually has no official designation and does not indicate that these models are dual ...
The Intel Core microarchitecture (provisionally referred to as Next Generation Micro-architecture, [1] and developed as Merom) [2] is a multi-core processor microarchitecture launched by Intel in mid-2006. It is a major evolution over the Yonah, the previous iteration of the P6 microarchitecture series which started in 1995 with Pentium Pro.
Improvements relative to the Intel Core processors were: A 14-stage instruction pipeline that allows for higher clock speeds. SSE4.1 support for all Core 2 models manufactured at a 45 nm lithography. Support for the 64-bit x86-64 architecture, which was previously only offered by Prescott processors, the Pentium 4 last architectural installment.
