专门割出576sp来打压HD7770么...NV是多能阉割啊，又能割出三个版本，而且就连660本身都不是完整的GK106。反正看着5组SMX构成192bit，3组SMX构成128bit，各种不科学啊.....
GK106-400 960sp 192bit 2GB GTX660 5组SMX 对手7870和7850
GK106-250 768sp 192bit 2GB GTX655(?) 4组SMX 对手7850，替代560ti和560
GK106-200 576sp 128bit 2Gb GTX650ti(?) 3组SMX 对手7770，替代560SE
NVIDIA Plans Two New SKUs Based on GK106 A little later this month, NVIDIA plans to launch the GeForce GTX 660, its first desktop GPU based on the 28 nm GK106 silicon. The GTX 660 carries NVIDIA's ASIC codename GK106-400. An internal document detailing other SKUs based on the GK106 in the works, was leaked to the web. According to a 3DCenter.org report, the two ASIC codenames GK106-250 and GK106-200 described in the document could be new SKUs.
The GK106-250, carrying a working title GeForce GTX 655, could have one of the five SMX units of the GK106 disabled, resulting in a CUDA core count of 768. According to the document, it features a 192-bit wide GDDR5 memory interface, holding 2 GB of memory, much like the GTX 660. The GK106-200, on the other hand, with a working title GeForce GTX 650 Ti, could feature just three of the five SMX units on the GK106 silicon, making up 576 CUDA cores. According to the document, it features 2 GB of GDDR5 memory across a 128-bit wide memory interface, much like the GK107-based GTX 650. The two SKUs could help NVIDIA seal gaps in its mainstream desktop GPU lineup.
还是觉得这SMX 位宽 显存配比各种不科学。等下周GTX660发布后看NV发布的构架图是不是阉割版
好吧。。gk106和gk107中间的空缺就这样被填满了。。。老黄你真狠。。
