Intel 810
From Wikipedia, the free encyclopedia
The Intel i810 chipset was released by Intel in early 1999 as a platform for the P6-based Socket 370 CPU series, including the Pentium III and Celeron processors. Some motherboard designs include Slot 1 for older Intel CPUs or a combination of both Socket 370 and Slot 1. It targeted the low-cost segment of the market, offering a robust platform for uniprocessor budget systems. The 810 was Intel's first chipset design based around a hub architecture which was claimed to offer better I/O throughput. [1]
[edit] Overview
There are 3 variants of the 810:[2]
- 810-L: microATX (4 PCI), no display cache, ATA33 hard disk interface.
- 810: microATX (4 PCI), no display cache, ATA33 and ATA66.
- 810-DC100: ATX (6 PCI), 4 MB display cache, ATA33 and ATA66.
Intel 810 attempted to integrate as much functionality into the motherboard as possible. Features include: [1][2]
- 66 and 100 MHz bus support
- 2 USB ports
- An integrated graphics processor.
- Based upon the Intel740 2D/3D accelerator.
- Optional dedicated video RAM cache or use of system RAM.
- Hardware motion compensation for DVD playback.
- Digital video output
- AC97 modem and audio
The hub design consisted of 3 chips, including the Graphics & Memory Controller Hub (GMCH), I/O Controller Hub (ICH), and the Firmware Hub (FWH). These components are connected by a separate 266 MB/s bus, double the previously typical 133 MB/s attachment via PCI-Bus. The added bandwidth was necessary because of increasing demands data transfer between components.[2]
810 supports asynchronous bus clock operation between the chipset and CPU (front side bus) and the system RAM. So, if the machine is equipped with a Celeron that uses only a 66 MHz bus, PC100 SDRAM can still be taken advantage of and will benefit the IGP.[2]
Boards based on the chipset rarely have an AGP expansion slot, leaving the user to make do with PCI for video card options. 810-based boards include an AMR expansion slot.
