The history of 90s graphics cards: Voodoo, RIVA, and the first GPUs

The 90s were an exciting and transformative period for computer graphics. During this decade, personal computers moved from displaying simple two-dimensional images to rendering complex three-dimensional worlds in real time. What began as hardware designed mainly to draw windows and icons eventually evolved into powerful graphics chips capable of transforming video games and digital media. Many of the technologies used in modern graphics cards can trace their origins back to this era. At the start of the 90s, most graphics hardware focused on improving 2D performance. Personal computers were becoming more common in both homes and offices, and graphical operating systems such as Windows were growing in popularity. However, drawing windows, icons, and text required significant processing power, which placed a heavy burden on the computer’s central processor. To address this issue, manufacturers began designing graphics chips specifically to accelerate these tasks. Companies such as S3 Graphics, ATI Technologies, and Matrox became well known for producing fast and reliable 2D accelerators. Chips like the S3 86C911 series, ATI’s Mach8 and Mach32, and the Matrox Millennium significantly improved the speed of graphical user interfaces. As a result, operating systems such as Windows 3.1 and later Windows 95 felt smoother and more responsive when running applications. Despite these improvements, most 3D graphics calculations were still handled by the CPU, which limited the performance of early 3D games.

By the mid-90s, video games were becoming more ambitious and demanded far more graphical power. Titles such as Quake and Tomb Raider required computers to render complex three-dimensional environments quickly and smoothly. This demand led to the development of dedicated 3D graphics accelerators that could handle these calculations much more efficiently than the CPU alone. One of the most influential companies of the era was 3dfx Interactive. In 1996, the company released the Voodoo Graphics card, which dramatically changed PC gaming. Unlike earlier solutions, the Voodoo card focused entirely on accelerating 3D graphics. It worked alongside a separate 2D graphics card and allowed games to render textures, lighting, and environments much faster than software rendering could achieve. The Voodoo cards introduced important features such as texture mapping, Z-buffering, and bilinear filtering, which made games look smoother and more detailed. Later versions like the Voodoo2 even allowed two cards to work together, increasing performance and setting an early example of multi-GPU technology. During the same period, NVIDIA was beginning its journey in the graphics market. One of its first products, the NV1 released in 1995, used an unusual rendering approach that was incompatible with many game engines. Although the product was not very successful, NVIDIA quickly learned from this experience. In 1997 the company released the RIVA 128, a much more conventional graphics chip that combined both 2D and 3D acceleration on a single card. Its strong performance helped establish NVIDIA as an important competitor in the growing graphics industry.

Other companies also joined the race to develop powerful 3D graphics hardware. ATI introduced the Rage series of graphics chips, which combined solid 2D performance with gradually improving 3D capabilities. Matrox entered the market with products like the Mystique and later the G200. Although some of these early cards did not always match the performance of 3dfx’s products, they contributed to the rapid pace of innovation and competition within the industry. Toward the end of the decade, graphics technology advanced even further. One of the most significant milestones occurred in 1999 when NVIDIA released the GeForce 256. This chip introduced hardware transform and lighting, commonly known as T&L. Previously, these complex calculations had been handled by the CPU, but the GeForce 256 moved them directly onto the graphics chip. Because of this capability, NVIDIA described the GeForce 256 as the world’s first GPU, or Graphics Processing Unit. This marked the beginning of a new generation of graphics hardware.

Several other important graphics chips appeared during this time, including the 3dfx Voodoo3, ATI Rage 128, and the S3 Savage3D. The Savage3D was particularly notable for introducing texture compression technology, which allowed games to use higher-quality textures without requiring as much memory. This technology would later become widely adopted in modern graphics systems. Software also played a key role in the development of graphics technology during the 90s. Graphics application programming interfaces, or APIs, allowed game developers to communicate directly with graphics hardware. Three major APIs dominated the decade: OpenGL, Direct3D, and Glide. OpenGL was widely used in professional graphics and later in games such as Quake. Direct3D, part of Microsoft’s DirectX platform, gradually became the standard for Windows gaming. Glide, developed by 3dfx, was optimized specifically for Voodoo graphics cards and provided excellent performance for supported games.

The rapid development of graphics chips throughout the 90s completely changed the personal computer industry. Technologies such as hardware texture mapping, real-time 3D acceleration, Z-buffering, and texture compression became essential features of graphics hardware. Although some early pioneers like 3dfx eventually disappeared from the market, their innovations helped shape the future of graphics technology. Today’s graphics processors are far more powerful, containing thousands of processing cores and supporting advanced technologies such as ray tracing and artificial intelligence. However, their roots lie in the groundbreaking work of the 90s. The fierce competition and rapid innovation of that decade laid the foundation for modern GPUs and transformed the way computers create and display digital worlds.
