History of nVIDIA Graphics cards Vol. 2 GPU competition
On August 31, 1999, nVIDIA announced the integrATion of hardware T&L (Transform and Lighting) into the graphics core, the first GeForce (Geometry Force) product-GeForce 256 graphics card, which pioneered the concept of GPU (Graphics Processing Unit). The GPU originally referred to display chips that support hardware T&L, but today, all display chips are collectively referred to as GPUs.
The GeForce 256 graphics card uses the T&L engine to share the processor computing load. For video games that support the T&L engine, the performance of the GeForce 256 can be fully utilized, bringing a revolution in 3D graphics performance.In fact, Geforce 256 won the title of "The world's first GPU" is very difficult, because there are two opponents in front of it.

May 11, 1999 ,3Dlabs announced the Oxygen GVX1, workstation graphics card.The GVX1 does not take nVIDIA's more cost-effective route of integrating hardware T&L support into the core.this using GLINT R3(Permedia 3) and one external chip ,this chip is GLINT Gamma G1, Geometry Processor.The GLINT Gamma G1 is capable of processing 4.75 million triangles per second.Although Oxygen GVX1 is a hardware T & L graphics card before Geforce 256, but they were not integrated into the graphics core.
The gaming performance of Oxygen GVX1 is only slightly better than TNT, and the professional 3D performance is only about half of Quadro 256. It is not difficult to understand why 3Dlabs has stopped selling chips since Permedia 3, and focused on mid-to-high-end professional graphic cards. As a result, 3Dlabs has missed a large number of entry-level professional graphics card users who can do professional work and meet general entertainment needs. Even if 3Dlabs acquired Intense3D in July 2000 and released the Wildcat II Series graphics card, it still could not escape the fate of being acquired by Creative Technology in June 2002.

The strongest rival of GeForce 256 is undoubtedly Savage 2000, which was announced by S3 the day before. S3 had high hopes for Savage 2000. On June 22, 1999, it made a desperate acquisition of Diamond, turning a chip manufacturer into a graphics card manufacturer. In November, it released the Viper II Z200 graphics card based on the Savage 2000 chip.
Savage 2000 hardware supports S3TL similar to hardware T&L, but the initial driver is based on DirectX 6 (DirectX 7 is the first version to support hardware T&L), resulting in S3TL not working at all and it is not a real GPU. The 3D performance is only 80% of the GeForce 256 graphics card, so S3 lost the title of "The world's first GPU". The miserable ending was acquired by VIA on August 5, 2000, and it exited the GPU competition early.

On the same day that nVIDIA announced the GeForce 256 graphics card, Videologic announced that the only Neon 250 graphics card using the PowerVR 250 chip will be sold in the UK.PowerVR 250 (PowerVR second generation) is a PC ported version of the Sega game console version PVR250DC jointly launched by Videologic and NEC on December 2, 1998.Compared with PVR250DC, the performance of PowerVR 250 has shrunk a lot, and the performance is still close to TNT2.This is because the PowerVR 250 display chip integrates unique TBR technology, which effectively reduces the burden on the CPU, but it is much inferior to the Geforce 256 graphics card that supports T&L with hardware.
The GeForce 256 graphics card is too powerful, and even the Rage Fury Maxx graphics card with dual RAGE 128 Pro cores on November 7, 1999 could not be matched by ATi. Rage Fury Maxx graphics cards are priced higher than GeForce 256 graphics cards, and their 3D performance is only about 80%, which is slightly weaker than Savage 2000 graphics cards.
