Intel Pentium processor was introduced in 1992 after Intel stopped using numerical nomenclature for x86 processors. Intel gave the name “Pentium” first for their fifth generation micro architecture called P5.
Since 1993 Intel released several versions of processors under this name which incorporate different features and technologies.
This article discusses about the major Pentium processor types and their specification.
The P5 (586) processor that was released under the Pentium trademark came with 3.1 million transistors and initial 66MHz clock speed. It also executes 112 million instructions per second.
In addition, this processor introduced a new technology called superscalar technology. Superscalar technology enables a processor to execute two instructions at the same time.
After the introduction of the first Pentium processor, Intel came up with various Pentium processor brands. The following are the major versions.
In 1995 Intel introduced Pentium Pro processor that was designed based on P6 processor architecture. New features such as Dynamic Execution and Dual Independent Bus Architecture are built in the P6 or sixth generation processor family. Dynamic execution enables the processor to have advanced 3D visualization and interactive capabilities.
Pentium Pro CPU specifications
Pentium II is the other type of Intel Pentium processor. This processor type is an extension of Pentium Pro processor which added MMX technology (multimedia extension) for multimedia applications.
Introduced in 1997, it has 7.5 million transistors and 300MHz initial speed.
Pentium Pro CPU General Specifications
The Pentium III processor was released in 1999. Initially, it has 9.5 million transistors with 300MHz speed. This Intel Pentium processor came with new additional features that were not found in the previous processors. These newly added features such as Streaming SIMD have benefited specifically advanced imaging, 3D video and audio applications.
Pentium III General Specifications
In 2000 Intel introduced breakthrough processor that runs at 1GHz speed. In addition, a new micro architecture called NetBurst is introduced by Intel. The NetBurst micro architecture incorporated features such as hyper pipelined technology, hyper threading technology, high speed system bus and cache.
Pentium 4 processor is designed based on NetBurst micro architecture.Pentium 4 processor initially built in with 42 million transistors and 1.5GHz speed.
Pentium 4 General Specifications
Pentium 4EE is the other Intel Pentium processor introduced in 2003. It is similar to Pentium 4 micro architecture but came with the highest clock speed and newly added L3 cache. It has 51KB L2 and 2MB L3 cache. Pentium 4EE speed ranges from 3.2GHz to 3.73GHz. This processor was specifically designed for the Gaming industry.
In 2005, Intel released its first desktop dual-core processor (two independent processor cores in a single package) called Pentium D. The number of transistors in Pentium D processor is 291 million and 3.2GHz initial speed. Pentium extreme edition is also the other dual-core processor, referred as the high-end version of Pentium D CPU. Unlike Pentium D it supports Hyper-threading technology and over clocking.
Pentium D Specifications
Intel Pentium M is a processor designed based on P6 micro architecture. This Intel Pentium processor family is for portable computing. Intel mobile processors incorporate several new features and technologies comparing to desktop processors.
Both Pentium dual core and Quad core processors are designed based on Intel’s new and highly efficient core micro architecture technology. Energy consumption is significantly reduced in core micro architecture while better performance is achieved.
Pentium Dual Core and Quad core Major Specifications
Since 2009, Intel introduced new processors under Pentium name both in single and dual-core versions. These processors are economical (low budget) and meant for bask computing.
The Intel Pentium Desktop processor has the following features:
As we have discussed in the above article, Intel Pentium processor has several versions which differs both in technology and performance.
This is an overview on one of the most prominent processor we find in computer systems. Therefore, before purchasing any type of processor it is always recommended to understand the features and the technology incorporated with the processor.
