我们从德国3Dcenter网站获悉，NVIDIA 16日将要发布的GeForce GTX 280图形芯片，其渲染效率将是上代G80图形芯片的1.5倍。另外，3Dcenter网站也给出了源自于NVIDIA官方的部分GTX 280参数： 1/处理核心数量提升1.88倍 2/每芯片线程数量提升2.5倍 3/寄存器文件尺寸翻倍 4/支持双精度浮点 5/更快的几何着色 6/1GB显存搭配512-bit显存控制器 7/更有效率的指令调度和分派 8/更高的工作频率，更有效率的显存访问 9/改进片上单元之间的通讯速度 10/改进Z轴压缩算法，提升纹理压缩性能和分辨率 11/支持10-bit色彩 NVIDIA上代图形芯片G80同时可以处理的线程数是12288个，那么根据NVIDIA官方资料推算GTX 280图形芯片同时可以处理的线程数是30720个，GTX 280图形芯片的整体性能将是G80的2.8倍。
