Intel 800 series

from Wikipedia, the free encyclopedia

The Intel 800 series is a family of Northbridges - referred to by Intel as Memory Controller Hub (MCH) or Graphics and Memory Controller Hub (GMCH) - which, together with a Southbridge , the I / O Controller Hub , is a chipset for x86 -Microprocessors made by Intel. The 800 series is closely related to the Intel E7000 series . The chipsets based on the 800 series are mainly used for the processors Intel Pentium III , Intel Celeron (P6) , Intel Pentium 4 and Intel Celeron (NetBurst) .

Product history

Note: The sorting of the following MCHs or GMCHs is not chronological, but is based on the numbering of the chips.

Pentium III chipsets

i810

The first chipset in the 800 series is the i810 (code name Whitney ) and was launched in April 1999. It was Intel's first IGP and should strengthen Intel's market position in the low-cost segment, in which graphics performance is negligible. Intel's competitors, e.g. B. SiS and VIA Technologies , have been able to offer corresponding IGPs for a long time and thus achieve a certain market share. The graphics core of the i810 was based on the i752 , a development by Real3D that was taken over by Intel. The i810 supported a maximum of 512 MiB PC-100-SDRAM and was designed for a Front Side Bus (FSB) of 100 MHz. The associated southbridge was the ICH or the ICH0 . The i810E was also combined with the ICH, but supported an FSB of 133 MHz, while the i810E2 is an i810E variant that was combined with the ICH2. In all versions of the i810, the memory was always controlled at 100 MHz, regardless of the FSB set.

i815

Intel 82815 (i815)

Due to the problems with the i820 and i840 chipsets, Intel launched the i815 (code name Solano ) and i815E in June 2000 . In contrast to the i820 or i840 chipsets, the i815 again supports SDRAM (PC-133), but the maximum memory expansion is only 512 MiB as with the i810. The i815 was combined with the ICH, the i815E with the ICH2. This was followed in November 2000, the i815EP and in March 2001 the i815P . While the ICH2 was also used in the former, it could be the ICH or the ICH0 in the latter. In September 2001, Intel then brought corresponding IGPs onto the market with the i815G (with ICH or ICH0) and the i815EG (with ICH2).

i820

The i820 (code name Camino ) was actually planned as the successor to the widespread Intel 440BX in November 1999 , but the costs for the necessary RDRAM were too high, so that potential buyers were put off either to mainboards with the older i440BX or to models from the competition . The sister model i840 also sold sluggishly. Although Intel offered mainboard manufacturers the option of controlling PC-133-SDRAM via the so-called Memory Translator Hub (MTH), this solution also proved to be expensive, error-prone and not very efficient. The i820 was followed by the i820E with the ICH2 in June 2000 .

i830

The i830 series (code name Almador ) was intended for notebooks and supported correspondingly extended energy-saving functions. The ICH3-M was used as the ICH. The i830M , i830MG and i830MP models differ mainly in the graphics options: no IGP or IGP with and without AGP .

i840

The i840 (code name Carmel ) was the sister model to the i820 and was equipped with a dual-channel RDRAM controller. It was marketed as a high-end chipset by Intel, but had problems similar to the i820.

Pentium 4 chipsets

i845

Intel i845 (Northbridge).

In response to the high cost of RDRAM, Intel released the i845 chipset (code name Brookdale ) in January 2002 , which has a memory controller for PC-133 SDRAM. The i845 only supported FSB 400, so the i845E for FSB 533 followed in May 2002 . In addition, it has a DDR-SDRAM memory controller and the ICH4 was used for the first time. With the i845G and i845GL , the first IGPs for the Pentium 4 were also released in May 2002. In October 2002 the i845GE , i845PE and i845GV followed

i848

The i848 was a trimmed version of the i865P and only supported a maximum of 2GB of RAM. It was launched in August 2003.

i850

The i850 (code name Tehama ) with the ICH2 was Intel's RDRAM chipset for the Pentium 4 . The high cost of the memory slowed down the Pentium 4's rapid market success. Nevertheless, in May 2002 the i850E was brought onto the market with support for FSB 533.

i860

As a chipset for the Intel Xeon with NetBurst architecture , Intel brought the i860 (Colusa) onto the market. This was quite similar to the i850, but supported up to 4 GiB of memory.

i865

In May 2003 the i865G (an IGP), the i865P and the i865PE (code name Springdale ) came on the market with the new ICH5 and ICH5R, respectively. The i865GV released in September 2003 was an i865G with no AGP.

i875

The i875P (code name Canterwood ) was the high-end version of the i865P and was released in April 2003. Above all, it offered a faster memory controller.
