The Dawn of the GPU: Nvidia's GeForce 256

On October 11, 1999, Nvidia introduced the world to the GeForce 256. While Nvidia had produced hardware before, this specific release marked the first time the company utilized the term GPU (Graphics Processing Unit) to market its product.

The "GPU" Debate

Whether the GeForce 256 truly earned the title of the "first" GPU is a point of contention. Enthusiasts of 3dfx would likely argue that their hardware already fit the description. Furthermore, the distinction between the GeForce 256 and its predecessor, the TNT2, feels somewhat arbitrary. While the GeForce was undoubtedly more capable and feature-rich, the fundamental idea of using a graphics coprocessor to relieve the CPU was already an established practice.

"If the GeForce 256 was the first GPU, it might simply be because Nvidia were the ones who coined the term."

Technical Nuance: Transform and Lighting

The defining characteristic of the GeForce 256 was its ability to handle T&L.

Texture Lighting $\rightarrow$ Transform and Lighting

This hardware-level offloading had varying impacts based on the user's system:

Despite this, the strategy of offloading tasks was visionary. By iterating on their hardware faster than Intel could update CPUs, Nvidia maintained a competitive edge.

The Sega Lifeline: A Near-Death Experience

Nvidia's current status as a global titan was nearly derailed in its infancy. Founded in 1993, the company entered a partnership with Sega in 1996 to develop the video hardware for the Dreamcast.

However, the project was a disaster:

1. Nvidia's chip failed to meet Sega's requirements.
2. The company completely ran out of capital.
3. The project stalled.

In a surprising move, Sega provided a **5 million investment** to keep Nvidia afloat. This gamble paid off handsomely for Sega, as they eventually realized a profit of: $$\text{Profit} = \text{Return} - \text{Investment} = \15\text{M} - $5\text{M} = $10\text{M}$$

Ultimately, the Dreamcast launched with an NEC chip (after Sega also weighed options from 3dfx).

The Path to Dominance

The financial infusion from Sega acted as a catalyst for a string of successful releases:

• Riva 128: Sold over one million units.
• TNT2: Built on the success of the Riva.
• GeForce 256: Established the GPU era.

Without Sega's intervention, Nvidia might have vanished, potentially allowing 3dfx to survive. Instead, the tide turned: Nvidia acquired the bulk of 3dfx's intellectual property on December 15, 2000, and 3dfx officially declared bankruptcy on October 15, 2002.

Community Perspectives

The article sparked a discussion among readers:

• Luyd Freitas expressed nostalgia for an era when Nvidia focused on consumers, lamenting their shift toward becoming an "AI company" with less regard for the end-user.
• Chris provided a technical correction regarding "T&L," noting that early cards handled texturing, but the breakthrough was specifically Transform and Lighting.
