The chip set which the Intel corporation announces in 1999 November. As for feature support and Direct RDRAM of 133MHz drive of system bus (RIMM), correspondence to the Advanced Capability of AGP 4x and ATA/66 etc. The number of on-board possible maximum processors corresponds to the system up to 2. 1999 late September shipment was planned, but because trouble is discovered to the support of Direct RDRAM, it has the details that shipment was postponed. Efficiency did not shake in comparison with 440BX of comparatively 1 where the price of Direct RDRAM is high generations ago, as a result without spreading completely was decided that production is discontinued on 2001 end of year.

Intel 820E

Field:
Personal computer > chip set > Intel 820E

The chip set which the Intel corporation announced in 2000 June, becomes the revised edition of “i820” of the same company. Direct RDRAM (RIMM) and, the functional other things where such as the support of AGP 4x i820 has, ICH2 (I/O Controler Hub 2) was adopted, Ultra ATA/100, USB of 4 ports and maximum of audio etc of channel 6 were supported.

Intel 840

Field:
Personal computer > chip set > Intel 840

Pentium with III of the Intel corporation Pentium III Xeon corresponding chip set, the product which becomes succession of 440GX chip set of the same company.

At one of the chip set which deals with the server and the work station, it was announced simultaneously with Coppermine edition Pentium III in 1999 October. As for code name when developing “Carmel”. In Pentium it corresponds III and Pentium III Xeon.

It was the schedule which supports the both of Direct RDRAM and SDRAM, but became the correspondence only of Direct RDRAM depending upon the trouble of MTH. In other things, it corresponds to Ultra ATA/66 and AGP 4x. Although you are proud of high basic efficiency because it is necessary to prepare expensive Direct RDRAM at 2 these units, there was no thing which excessively is widely used.

Intel 845

Alias:
Brookdale
Field:
Personal computer > chip set > Intel 845

It appeared in 2001 September, for Pentium 4 of the Intel corporation chip set. With the product which was called in the code name, “Brookdale”, it corresponds to PC133 SDRAM.

Inexpensive memory and because Pentium 4 can be combined, low price it is possible to construct the Pentium 4 machine. But, because memory zone is only the 1/3 of PC800 RDRAM, efficiency of the machine which uses i845 15% decreases from 10% in comparison with the efficiency of the machine which uses Intel 850.

In addition, besides the fact that it corresponds to AGP 4x, you use the same as i815E/i850 and the like ICH2, in USB correspond 1.1 and Ultra ATA/100 etc.

As the variation of i845, i845 B-Step of 2002 January release (in PC2100 DDR SDRAM correspondence) and i845E (in USB 2.0 correspondence etc) /i845G of 2002 May release (in addition to the function of i845E built-in graphics loading) /i845GL (instead of built-in graphics being attached to i845E you cannot use external graphics,) is.

Intel 850

Field:
Personal computer > chip set > Intel 850

With Pentium 4 corresponding chip set of the Intel corporation, the product which undertakes the succession of i820. Release it is done simultaneously with Pentium 4, supports only Direct RDRAM. As for code name when developing “Tehama”.

As for input/output interface ICH2 which is common with i820E/i845 is adopted, Ultra ATA/100 and Ethernet (100BASE-TX) and the like builds in.

As for i850 corresponding, the inside FSB of Pentium 4 has become those of 400MHz (423 pins 478 pin sooner or later correspondence) with, corresponding to the product of FSB 533MHz has become i850E of 2002 May release (Tehama-E) with. As for the function of i850 and i850E in the difference of FSB which is corresponding, almost there is no modification of interface and the like.

Intel 855 chipset family

Reading: The Intel bee - -
Alias:
855, i855
Field:
Personal computer > chip set > Intel 855

Pentium M corresponding chip set series of Intel corporation. 855GM which builds in graphic function general term of 3 products of 855GME of the revised edition of 855PM and 855GM which are not built in. Pentium M and 855 series chip sets, the package which combines three of wireless LAN tip/chip “Intel PRO/Wireless” is called Centrino. As for development cord/code name 855GM “Montara-GM” and 855PM “Odem”.

Also 3 products correspond to FSB of 400MHz, support DDR SDRAM of maximum 2GB and USB 2.0 etc. Combining ICH4-M you use for the southern bridge. As for DDR memory as for 855GM to correspond to DDR266, as for 855PM and 855GME to DDR333 available. 855GM/GME builds in Intel Extreme Graphics 2 as a graphic function, 855PM corresponds to the external graphics of AGP 4x.
