nVidia has kicked off the next graphics card battle between itself and rival ATi with the launch of its new GeForce 7800 GTX GPU, codenamed G70. The new GPU is a completely new core, claims nVidia, and uses the company’s new Cine FX 4.0 engine. Compared to nVidia’s older GeForce 6800 GPU, which offers 16- and 6- pixel and vertex shader pipelines, the new GPU offers wider 24- and 8-pixel pipelines. These wider pipelines will speed up the process of adding textures and effects to on-screen graphics. Thanks to these beefed up specs, the 7800 GTX GPU runs at 430MHz, which is the same core-speed that nVidia’s 6800 Ultra GPUs are clocked. The G70’s performance should beat that of the older GeForce 6800 Ultra. vVidia even claims that a single 7800 GTX card will outperform two GeForce 6800 Ultra cards running in SLI mode (where two cards run in parallel for better performance). For gamers with deep pockets and a lust for the fastest and most fluid gaming experience, nVidia has also furnished the 7800 GTX with SLI capabilities. Despite the 7800 GTX’s more complex core, which sports a cool 302 million transistors, power consumption has dropped below that of the 6800 Ultra, though the G70 is still a power hungry beast, consuming between 100 and 110W of power. Graphics card manufacturers Albatron, Gainward and XFX have already announced cards based on the new technology, with prices expected to be just a tick under $600.
