what is pentium I pentium II or III or IV?

Question

is it regarding speed if yes then what is the speed reference by which we can distinguish different processors that this is pentium I this is another.

Answer 1

Hi there;

They signify the generations or progressions (evolutionary development) of the chip set by Intel. :)

Yes, the speed (measured in megahertz) is faster, however, with the intro of the Pent. II there is also the intro if a chip cashe and bus.
The Pent I ran at 60 Mhz, the Pent II ran from 233 Mhz to 450 Mhz with a FSB speed clocking in at 100 MHz. The Pent III runs at 450 to 1.4 GHz.
The Pent IV runs at 3 GHz with a FSB of 533 MHz.

Answer 2

The Pentium variety refers to Intel's single-center x86 microprocessor based on the P5 5th-technology microarchitecture considered here as such basically. The call 'Pentium' replaced into derived from the Greek penta, meaning '5', and the Latin ending -ium. presented on March 22, 1993, the Pentium succeeded the Intel486, which quantity "4" signified the fourth-technology microarchitecture. commencing in 1995, Intel (erratically) used the "Pentium" registered trademark in the names of families of placed up-5th-generations of x86 processors branded because of the fact the Pentium professional, Pentium II, Pentium III, Pentium 4 and Pentium D. in spite of in the event that they shared the x86 guidance set with the unique Pentium (and its predecessors),

Answer 3

The lower the Pentium model the older it is.
And now they have newer technology than Pentium..the Intel Core 2 Duo and the Intel Core 2 Extreme processors.

Answer 4

Yes you can tell the diffrence between pentium chip either visualy or by checking the BIOS. Typicaly the CPU will have the trademark pentium symbol on it indicating the generation. If that fails (and this is probably why your asking...) if it looks old it probably is. You can alos tell by the chip set. Pentuim 4 and celeron take a 478 or 775 chip set while P3 and P2 takes 8xx chip set.

Answer 5

The Pentium is a fifth-generation x86 architecture microprocessor from Intel.

Pentium I, II, III, IV and Pentium D are its upgrades.

Answer 6

Like cars change their models like Mark 1, 2, 3 etc, the pentium is also evolutionary progress of the computer chip improving on its processing capacity.

Answer 7

these r the generations of the processors and these depends on capacity and speed and the memory of tht processor

Answer 8

The Pentium 4 is a seventh-generation x86 architecture microprocessor produced by Intel and is their first all-new CPU design, called the NetBurst architecture, since the Pentium Pro of 1995. Unlike the Pentium II, Pentium III, and various Celerons, the architecture owed little to the Pentium Pro/P6 design, and was new from the ground up. The microarchitecture of Netburst featured a very deep instruction pipeline, with the intention of scaling to very high frequencies. It also introduced the SSE2 instruction set for faster SIMD integer, and 64-bit floating-point computation.

The original Pentium 4, codenamed "Willamette", ran at 1.4 and 1.5 GHz and was released in November 2000 on the Socket 423 platform. Notable with the introduction of the Pentium 4 was the comparatively fast 400 MT/s FSB. It was actually based on a 100 MHz clock wave, but the bus was quad-pumped, meaning that the maximum transfer rate was four times that of a normal bus, so it was considered to run at 400 MT/s. The AMD Athlon was running at 266 MT/s (using a double-pumped bus) at that time.

As is traditional with Intel's flagship chips, the Pentium 4 also came in a low-end Celeron version (often referred to as Celeron 4) and a high-end Xeon version intended for SMP configurations.

The Pentium 4 line of processors was retired on July 27, 2006, replaced by the Intel Core 2 line, using the "Conroe" core.


The Pentium III is an x86 (more specifically, an i686) architecture microprocessor by Intel, introduced on February 26, 1999. Initial versions were very similar to the earlier Pentium II, the most notable difference being the addition of SSE instructions and the introduction of a controversial serial number which was embedded in the chip during the manufacturing process. As with the Pentium II, there was also a low-end Celeron version and a high-end Xeon version. The Pentium III was eventually superseded by the Pentium 4. An improvement on the Pentium III design is the Pentium M.



The Pentium II is an x86 architecture microprocessor by Intel, introduced on May 7, 1997. It was based on a modifed version of the P6 core first used for the Pentium Pro, but with improved 16-bit performance and the addition of the MMX SIMD instruction set which had already been introduced on the Pentium MMX.

The original Klamath Pentium II ran at 233 and 266 MHz, were produced in a 0.35 µm fabrication process and produced (for that time) an incredible amount of heat. They also worked with a 66 MHz front side bus, which was a speed that was inadequate for the CPU's design to show its full potential. A 300 MHz version was released later in 1997.

The Deschutes core Pentium II, which debuted at 333 MHz in January 1998, was produced in a more suitable 0.25 µm fabrication process and ran significantly cooler. Support for 100 MHz front side bus speeds heralded solid performance improvements. During 1998, Pentium IIs running at 266, 300, 350, 400, and 450 MHz were also released. Pentium II-based systems also saw the introduction of the new generation RAM-standard, SDRAM (which replaced EDO RAM), and the AGP graphics bus.

Unlike previous Intel processors such as the Pentium and Pentium Pro, the Pentium II was packaged in a slot-based form-factor rather than a socket. The chip and associated components were carried on a daughterboard similar to a typical expansion board within a plastic cartridge. A fixed or removable heatsink was carried on one side, sometimes using its own fan. This larger package was a compromise allowing Intel to separate the secondary cache from the processor while still keeping it on a closely coupled bus. This separate cache was slower (running at half the processor speed) than that in the Pentium Pro, but the smallest cache size was increased to 512 KiB from the 256 KiB on the Pentium Pro. Off-package cache solved the Pentium Pro's low yields allowing Intel to introduce the Pentium II at a mainstream price level.

This arrangement also allowed Intel to easily vary the amount of L2 cache, thus making it possible to produce inexpensive but low performance and expensive but high performance versions of the CPU using the same core chip. Intel reverted to the more usual format of placing the processor on the mainboard with the Pentium III but continued the practice of selling essentially similar chips with small and large cache sizes, with the L2 cache moved onto the die itself.

The low-end version of the Pentium II - essentially a Pentium II with less (or none) level 2 cache - was marketed under the name "Celeron". It was not well received by many IT professionals due to substantially lesser performance compared with the more expensive product with L2 cache. However, the lack of the off-die L2 cache allowed for more flexibility with overclocking (the missing L2 cache was more sensitive to overclocking than the main chip). This overclockability led to heat issues, and the Pentium II Celeron was one of the first chips for which aftermarket companies started to produce high performance cooling such as water-based or refrigerant cooling.

The Pentium II Xeon was a high-end version intended for use on servers. Principally, it used a different type of slot (Slot 2), case, board design and used expensive full-speed L2 cache, which was again off-die. Versions were produced with 512 KiB, 1 MiB or 2 MiB L2 caches by varying the number of 512 KiB chips incorporated on the board.

The Pentium 1 is a fifth-generation x86 architecture microprocessor from Intel, developed by Vinod Dham. It was the successor to the 486 line, and was first shipped on March 22, 1993.

The Pentium was originally to be named 80586 or i586, to follow the naming convention of previous generations. However, Intel was unable to convince a court to allow them to trademark a number (such as 486), in order to prevent competitors such as Advanced Micro Devices from branding their processors with similar names (such as AMD's Am486). Intel enlisted the help of Lexicon Branding to create a brand that could be trademarked. The Pentium brand was very successful, and was maintained through several generations of processors, from the Pentium Pro to the Pentium Extreme Edition. Intel has retired the brand and replaced it with the "Intel Core" brand. The first Intel Core, released in January 2006, extended the Pentium M microarchitecture. The Intel Core 2, released in July 2006, features the new Intel Core Microarchitecture.

In programming, it is sometimes necessary to distinguish the original Pentium processor architecture from later Pentium-branded architectures. For these cases, i586 is often used to refer to all the early Pentium processors, as well as processors made by Intel's competitors that can run machine code targeted to the early Pentiums.
