一提起3D图形加速卡,大多数人可能首先想到的是诸如:nVIDIA、3dfx、Matrox等在市场中大红大紫的芯片厂商,的确目前nVIDIA风头正劲,第六代显卡也已全面上市。绘图芯片厂商诸侯混战的局面正愈演愈烈。目前nVIDIA公司在全球发布了其最新的NV 15图形芯片,它的性能比原来的GeFoice 256要快3倍左右,NV15采用了单周期4像素,双材质单像素的技术,因此在多重贴图的游戏中将可以提升近2～3倍的速度,其工作的核心频率更可达到200MHz,在T&L(硬件转换与光影)中可提升多达45％的性能。而内存则配备了400MHz高性能DDR显存。它造就了在运用单像素上的单材质游戏软件可以达到每秒640MB pixel的填图速率,更胜一筹的是由于NV15支持双材质单像素,故在双材质下NV15也同样拥
When it comes to 3D graphics acceleration cards, most people may think of such chip companies as nVIDIA, 3dfx, Matrox, and others in the market. It is true that nVIDIA is advancing at the moment and the sixth-generation graphics cards have also been fully listed. The situation where the graphics chip vendors are scrimming with each other is becoming increasingly fierce. At present, nVIDIA has released its latest NV 15 graphics chip in the world. Its performance is about 3 times faster than the original GeFoice 256. The NV15 uses a single-cycle 4 pixel, dual-material single-pixel technology, so it is a multi-mapped game. Will be able to improve the speed of nearly 2 to 3 times, the core frequency of its work can reach 200MHz, in T & L (hardware conversion and light and shadow) can increase performance up to 45%. The memory is equipped with 400MHz high-performance DDR memory. It created a single-pixel game using single-material game software can achieve mapping rate of 640MB pixels per second, even better because NV15 supports dual-material single-pixel, so under the dual material NV15 also holds the same
