7770提供90%的6850性能，比6850贵10刀。稍坑爹。
=6850清货差不多才会降价。

功耗相较6850，待机满载也差不多低10%。
温控很可观。


The problem for AMD today isn’t the power/performance curve, it’s the price/performance curve. 16 months ago AMD launched the Radeon HD 6850 at $179 amidst fierce competition from NVIDIA. Ignoring the current price of the 6850 for the moment, on average the 7770 delivers 90% of the 6850’s gaming performance for 90% of the 6850’s launch price. In other words in 16 months AMD has moved nowhere along the price/performance curve – if you go by launch prices you’re getting the same amount of performance per dollar today as you did in October of 2010. In reality the 6850 is much cheaper than that, with a number of cards selling for $159 before a rebate, while several more 6870s sell for $159 after rebate. The 7770 is so far off the price/performance curve that you have to believe that this is either a pricing error or AMD is planning on quickly halting 6800 series production.


7770发布价159刀，比6850发布价低10%，和目前性能比相当，但是高于6850现价。
