486 motherboards using the SiS 85C496/85C497 chipset © 199? Unknown
The SiS 85C496 (Northbridge) / 85C497 (Southbridge) chipset is a highly significant "final generation" chipset for the 486 platform. It represents the pinnacle of 486-era integration before the complete industry shift to the Pentium architecture.
Architecture: This chipset was designed to bridge the gap between legacy 486 processors and modern bus standards. It is one of the few 486 chipsets that successfully implemented a robust PCI 2.0 interface, allowing for high-speed peripherals that were previously bottlenecked by the ISA or VLB buses.
The "Performance Equalizer": When paired with a fast AMD 5x86 CPU, motherboards using the SiS 85C496/85C497 achieved performance benchmarks that rivaled entry-level Pentium 60/66 systems, but at a significantly lower cost.
