[b]GF100主要变化是：
几何细节质量的提升 （忽悠的？）
更好的图像质量 （相对的？）
革命化的游戏用GPU计算 （吹嘘的？）
前所未有的最强大的GPU性能[/b] （堆来的？）
GF100主要规格规格：
512CUDA单元
16几何处理器
4个光栅处理单元
64纹理处理单元
48个ROP
384位GDDR5显存
GF100架构能力：
8倍于GT200的几何处理性能
32x CSAA和三倍于GT200的Shadow Map性能
4倍的PhysX性能、AI和光线追踪
8x AA下两倍于GT200的性能

GF100之前，几何细节性能进步很小：从FX5800到GT200 shader性能提升超过了150倍，而几何性能仅提升三倍不到。DX9/DX10这些API的进化不能解决这个问题，但GF100全新的几何处理架构却给DX11带来了8倍的性能提升。 而Tessellation细分曲面技术可以将简单的模型赋予更复杂的细节，动态LOD运行模型细节在性能和质量之间依据需求进行调整。细分曲面和位移映射技术可以提供更丰富的几何细节。如GF100的火箭雪橇techdemo里的地形细节就是使用这样的技术。GF100的细分曲面性能大概有5870的2-6倍。GF100 Unigine DX11 Benchmark的DX11性能也在5870的1.5倍以上。GF100的DX11 SDK的GS性能更在5870的四倍以上。
As you look at the charts below, you will notice that we added in “simulated” HD 5870 1GB results and there is a story behind this。
The first indications seem to be that NVIDIA is definitely on the right track with the GF100 since it performs far above and beyond the older GTX 285. When you look at it in comparison to the current single GPU champ –the HD 5870 1GB – there just isn’t any competition at all and we are positive that even a highly overclocked HD 5870 won’t come anywhere near the GF100 we were shown.
In the past, we found that performance at this resolution in Far Cry 2 DX10 resulted in a fair amount of framebuffer limitation. However, NVIDIA has worked hard to make sure as much of the graphics processing data stays on-die within the cache before finally being handed off to the memory, which will carry huge benefits in games like this one.
话说这评测应该上5970吧？！5870都干不过出来浪费资源呢?
