At one of 32 bit microprocessors of the Intel corporation which is announced in 2003 November, the derivative product of Pentium 4.

It is the processor for the power user of the individual who does the 3D action game and high resolution video compilation etc daily. Celeron of inexpensive edition and Pentium 4 of the main stream, in the product series, Xeon for the server, it was so far overlooked, you can call the product which is directed to the user layer “of the opening”.

Basic structure conforms to Pentium 4, but it corresponds to Hyper-Threading which hypothetically actualizes dual processor, the secondary cache of 512KB, it builds in 3 next cash of 2MB which is not to Pentium 4. As for operational frequency with 3.2GHz, as for the based clock it corresponds to 800MHz. To be designed with 0.13 millimicron process, as for corresponding chip set the Intel 865 series and the Intel 875 series.

Pentium D <Pentium D>

Reading: Pentium D
Field:
Microprocessor > x86/Intel > Intel > Pentium D

32 bit microprocessor of the Intel corporation which is announced in 2005 May. The processor core two was built in to one tip/chip is designed to be “dual core” structure, 2 times that of the former processor close efficiency is shown.

With the main stream product for the desktop which becomes the succession of Pentium 4, it corresponds to 64 bit expansion functional “EM64T” and the memory protect functional “NX bit”. In the product of part also “Enhanced SpeedStep” of power control technology is built in. It does not correspond to Hyper-Threading, the respective core it operates as one processor. L2 cash of 1MB is built in every core. System bus (FSB) 800MHz. The same company individual “model number” is used in efficiency inscription. As for the product which at the beginning is announced “840” “830” in 3 types “of 820”, as for the respective actual clock it operates with 3.2GHz, 3.0GHz and 2.8GHz.

Pentium II <Pentium two>

Reading: Pentium two
Field:
Microprocessor > x86/Intel > Intel > Pentium II

It was announced in 1997 May, 32 bit microprocessor of the Intel corporation (MPU) one.

Being something which adds MMX of multimedia expansion instruction set to the Pentium Pro processor, basic efficiency is not different from Pentium Pro, but it is possible being maximum, to operate the software of the game and the image processing etc which are optimized in MMX to 60% high speed.

The 6th generation of the x86 processor family of the same company (the P6 core) it hits.

Because the secondary cache is designated as external, it was possible, became main current for personal computer CPU to reduce production cost Pentium Pro compared to.

It is supplied, the CPU core and the secondary cache, as the cartridge which supplies the cooling fan interface outside corresponds to Slot1 of slot type.

Pentium III <Pentium three>

Reading: Pentium three
Field:
Microprocessor > x86/Intel > Intel > Pentium III

32 bit microprocessor of Intel corporation (MPU). Those which administer various extensions to the core part of the Pentium II processor. It is known with the code name “of Katmai,” the 6th generation of the x86 processor family of the same company (the P6 core) hits.

SSE of the multimedia expansion instruction set which is MMX revised edition (before the formal release was called KNI) and, PSN and the like of each processor specific identification number is loaded.

As for SSE unless software side is corresponding, because it cannot utilize, it does not contribute to the improvement of performance of the former software.

Interface outside corresponds to Slot1 of the same slot type as Pentium II.
