As a result, motherboards began to favor the new bus over the old ones. ![]() However, this changed when the 3D graphics card industry took off, and the best cards featured PCI connectors. Despite these advantages, PCI took some time to gain traction in the motherboard industry, particularly in the workstation and server markets.Ĭan you name all these sockets? Image: Hardware MuseumĪt that time, home PC users typically did not have many expansion cards, or any that placed significant demands on the bus. A typical VLB expansion slot was also much larger than a PCI one. However, it wasn't always stable at that rate and had worse latencies than PCI. In contrast, VLB ran at the same clock as the CPU's front-side bus (FSB), allowing VLB to reach 40 or 50 MHz, depending on the central processor. While improvements to the technology weren't as successful in comparison, the system in general became ubiquitous within the industry.īy the time the next decade arrived, faster processors helped push the need for better-performing expansion buses, ultimately giving rise to two new formats – the PCI bus (Peripheral Component Interconnect) from Intel and the VLB (VESA Local Bus) from the Video Electronics Standards Association.īoth appeared at the same time in 1992, though PCI initially looked the slower of the two, as it was designed to run at a fixed 33 MHz (a later revision of the specification did permit 66 MHz, but consumer PCs never really supported this). For the latter, one type primarily dominated the domestic scene: IBM's ISA bus (Industry Standard Architecture). Let's start by heading back to the 1980s when computer motherboards were festooned with dozens of chips and a multitude of peculiar expansion slots for adding extra cards. If you're wondering exactly what it does and how PCI Express has remained a staple part of every home computer for two decades, then you've come to the right place. It may come as a surprise, then, to learn that it has been around for 20 years! With no signs of being replaced, the technology must be something special to last this long.
