What's Pentium?

Intel launched its new generation of High-performance processor Pentium in 1993. As the competition in the CPU market tends to become fiercer, Intel decided that it was no longer possible for AMD and other companies to use the same name to rob their jobs, so the trademark registration, because in the U.S. law can not be registered in Arabic numerals, so Intel played a pattern, in Latin to register trademarks.

Pentium in Latin is the meaning of "five". Intel also has a pretty good Chinese name for it to Pentium. Pentium's manufacturer code is P54c,pentium's internal number of transistors containing up to 3.1 million, clock frequency from the initial launch of the 60MHZ and 66MHZ, after the increase to 200MHZ. The original version of the 66MHZ Pentium microprocessor, its operational performance than 33MHZ 80486DX increased by more than 3 times times, while the 100MHZ Pentium is faster than 33MHZ's 80486DX 6 to 8 times times. That is, from the beginning of the Pentium, with overclocking such a good method with as little money as possible to exchange as much performance.

As the world's first level 586 processor, Pentium is also the first overclocking most of the processors, because of the excellent manufacturing process Pentium, so the entire series of CPU floating-point performance is also a variety of performance is the most powerful CPU, overclocking the most performance, So it won most of the market for tier 586 CPUs.

Pentium family inside the frequency has 60/66/75//90/100/120/133/150/166/200, as for CPU internal frequency is from 60MHz to 66MHz range. It is worth mentioning that, starting from Pentium 75, the CPU socket technology formally from the previous SOCKET4 to support SOCKET5 and 7 at the same time support, which SOCKET7 has been used to date. And all the pentiumcpu have built-in 16K cache, making it more powerful to handle.

The development of Pentium

Pentimupro

Intel, which initially occupies part of the CPU market, did not stop, and in 1996 it launched the latest generation of the sixth generation X86 series CPU date P6, as other companies continued to pursue their own Pentium. P6 is only its research code, after the listing P6 has a very loud name of the date Pentimupro. The interior of the Pentimupro contains up to 5.5 million transistors with an internal clock frequency of 133MHZ and processing speed of almost twice times the Pentium of 100MHZ. The Pentimupro (in-chip) cache is a 8KB instruction and 8KB data.

Pentium II

A X86 architecture processor for Intel, based on the P6 micro-processing architecture used by Pentiumpro, but on the other hand its 16-bit processing power is optimized and the MMX instruction set is added:

The first generation of Pentiumii core code for Klamath, using 350 nm process, and, at that time, to create a very high heat. Launched when the pulse is only 233 and 266MHz, the use of 66MHz front-end bus, the later launch of another 300MHz version of the Pulse, the second generation of Pentiumii core code for the Deschutes, the operating pulse for 333MHz, launched in January 1998, the use of 250 nm process, And the temperature is also effectively reduced. Support for the 100MHz front-end bus, Intel introduced a pentiumii processor with a pulse of 266, 330, 350, 400 and 450 in 1998.

The PENTIUMII computer system also adds a new generation of memory standard--sdram(to replace Edoram), and AGP graphics cards.

Pentium M

The new mobile Cpu,pentium m, specially designed by the Israeli team, is the Intel Corporation's x86 architecture microprocessor for use in notebook PCs and was launched in March 2003 as part of Centrino.

Pentium EE

The Pentiumee series are labeled in three-digit numbers, in the form of pentiumee8xx or 9xx, such as PentiumEE840, and so on, the larger the number, the higher the specification or the more supported features.

Pentium E2200

After a Core2duo processor's baptism of high-end markets, Intel unveiled a new generation of low-end dual-core processor PentiumE2000 series in the second quarter of 07, focusing on the entry-level dual-processor market, which focuses on cost-performance. The first batch of PentiumE2000 series includes two products, E2160 and E2140 respectively, with a frequency of only 1.8GHz and 1.6GHz, but the performance is very strong enough to meet the needs of most users.

Pentium G620

Pentium G620 can be viewed as a further compact version of Core i3 2100, including new features that do not support Sandy Bridge, such as the AVX instruction set.
