Intel EY82C621A: The Cornerstone of the 810 Chipset Platform
In the landscape of personal computing, the transition to more integrated and cost-effective solutions was significantly accelerated by the introduction of the Intel 810 chipset. At the heart of this platform lay a pivotal component: the Intel EY82C621A memory and graphics controller hub, a device that redefined value-oriented computing at the turn of the millennium.
The 810 chipset was Intel's strategic answer to the growing demand for affordable, yet capable, PCs for the home and business markets. It marked a decisive shift away from the traditional North Bridge/South Bridge architecture towards a more centralized, three-chip design: the Graphics and Memory Controller Hub (GMCH), the I/O Controller Hub (ICH), and the Firmware Hub (FWH). The EY82C621A is the formal component designation for the GMCH within this platform, making it the absolute core of the system.
Its primary role was to manage the critical communication between the processor, memory, and graphics. It was designed to support the latest Intel Celeron and Pentium III processors utilizing Slot 1 or Socket 370 interfaces. A key feature was its integrated Intel Direct AGP 3D graphics, which eliminated the need for a separate, discrete graphics card. This integration was a monumental step in reducing the total bill of materials for OEMs, allowing them to produce incredibly competitive systems. While not a performance powerhouse for hardcore gaming, this integrated solution was perfectly adequate for the business applications, educational software, and basic multimedia consumption of the era.

Furthermore, the EY82C621A GMCH was notable for its memory support. It was one of the early champions of 133 MHz SDRAM, providing a significant bandwidth improvement over previous-generation chipsets that were limited to 100 MHz. This support ensured that systems could keep pace with the increasing speed of CPUs, mitigating potential bottlenecks and delivering a smoother overall user experience. Its support for Hardware Motion Compensation also enhanced the playback quality of DVD video, a burgeoning technology at the time, which was a major selling point for home entertainment PCs.
The chip's design also facilitated the Advanced Configuration and Power Interface (ACPI), enabling more robust power management features that were essential for the sleep and resume functionality becoming standard in modern operating systems like Windows 98 and Windows 2000.
In conclusion, the Intel EY82C621A was far more than just a simple component; it was the architectural linchpin of a platform that democratized computing. By integrating critical functions and supporting new standards, it provided a balanced blend of adequate performance, exceptional cost-efficiency, and forward-looking features, paving the way for the ubiquitous integrated graphics platforms that dominate the market today.
ICGOOODFIND: The Intel EY82C621A (GMCH) is a landmark IC that defined value computing. Its integration of graphics and support for 133 MHz SDRAM made it the essential, cost-reducing engine powering the widespread adoption of the Intel 810 chipset platform.
