HD7750，HD7770 AnandTech测评，目前稍坑爹。
本帖最后由 kitsuki 于 2012-2-15 16:15 编辑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。

性能差距，可能是驱动造成的吧

对，驱动改善后，应该能超6850。
最终因该是目前6850的价格，稍高的性能，低功耗低温度。

{:3_161:}个人估计是，等68XX清仓得差不多了，就会放性能级别大提升的77XX的驱动出来了
买7950属于赌一把，性能上来说不错，功耗控制的不错，就看咋屏蔽的，能不能破解 kitsuki 发表于 2012-2-15 16:10 static/image/common/back.gif

和驱动无关 看下位宽和光栅就知道了 开了AA差距会更大
这些都是硬条件 驱动没那么逆天
老新闻，7770价格坑爹性能弱国外有评测。到国内价格估计还要卖贵点，国内价只能比国外的高 7770性能估计不弱，只是催化在作怪而已
