NVIDIA GeForce 7800 GT: XFX Style
Introduction & Specifications
It's been only about seven weeks since the GeForce 7800 GTX was officially launched on June 22, but NVIDIA is already making news yet again today with the latest addition to their GeForce 7 Series of cards, the new GeForce 7800 GT. As its name implies, the GeForce 7800 GT is very similar to NVIDIA's current flagship GeForce 7800 GTX, but the GT is launching with a significantly lower MSRP for a couple of reasons. Both cards are based on the GPU formerly codenamed "G70", however, the GeForce 7800 GT has four less pixel pipelines and is missing one vertex unit when compared to the GTX version. The new GeForce 7800 GT's reference specifications also call for lower core and memory clock speeds than the GeForce 7800 GTX, but we don't think NVIDIA's reference specifications are going to be followed by their board partners. The XFX card that we tested for this article surely didn't.
Due to the fact that the new NVIDIA GeForce 7800 GT GPU is based upon the same core architecture as the GeForce 7800 GTX, it shares essentially the same feature set as its higher-powered counterpart. We've detailed NVIDIA's latest architecture in-depth in our original coverage of the GeForce 7800 GTX launch back in June, so we'd recommend perusing that article if you're not familiar with what the GPU formerly code named G70 brings to the table. On top of everything offered by NVIDIA's previous flagship GeForce 6800 Ultra (NV40), the G70 GPU incorporates new anti-aliasing modes in the Intellisample 4.0 engine that improve the appearance of partially transparent textures, such as those used in many outdoor scenes for foliage. The G70 also has an updated dedicated video processor, dubbed PureVideo, with more features than its predecessor. And of course, the G70 has enhancements to its pixel and vertex shader pipelines for increased performance, as well.
