With the release of the GeForce 256 by NVIDIA, we will begin to see a flurry of new choices appear on the horizon. The GeForce256-chip marked a new mile stone in mainstream graphics when it was released in October 1999, because it is the first chip with integrated 'transform and lighting'. The inclusion of 'TnL' enables GeForce to take a lot of geometry-workload off the shoulders of the main system processor and gives the user the chance to enjoy 3D-graphics with a lot more polygons than before, resulting in much more detailed 3D-scenes. Currently, NVIDIA's GeForce256 is clearly the fastest and most advanced 3D-chip available, so that graphics card with this new chip are certainly of very high interest to all hard-core gamers and power users out there. GeForce's integrated 'T&L' is right now hardly used by any game though. Only Quake3 Arena and a few others can take advantage of this new technology right now. NVIDIA has promised that soon there will be a lot of 'T&L-games' available, but until then you won't be able to take too much advantage of GeForce's shiniest new feature.
GeForce256 and its Video-Memory
Tom's Hardware Guide has reviewed NVIDIA's GeForce256-chip thoroughly in several articles. If you should not be familiar with this chip yet, I'd recommend familiarizing yourself with GeForce with those three articles:
After reading the above reviews, you will certainly remember that there is an important issue with GeForce and its local, 'onboard' or 'video-' memory. NVIDIA designed GeForce so that it can either be equipped with normal and well-known SDRAM-memory or with the upcoming DDR (double data rate) memory instead. The latter memory type is basically double as fast as normal SDRAM, which almost doubles GeForce's memory-bandwidth and therefore improves its 3D-performance at true-color and/or high resolutions significantly. Unfortunately there isn't enough DDR-memory available right now, which is why you won't find GeForce-cards from any vendor equipped with this new high-speed memory yet. Please keep this in mind before you go and buy any of the GeForce-cards right now, because it might not take long anymore and DDR-equipped GeForce cards will also become available. Those cards will probably ship for a higher price but they will enable GeForce to show its full 3D-gaming potential.
