晶圆的诅咒~

The curse of wafer

Some K10, Barcelonas can go over 2.6 and all the way to 2.8 or even 3.0 GHz but most of them at least the ones that are going to come as corner chips on the wafer and not going to work at much higher speed than 2 GHz if not less.

This can explain why the first Barcelona we pictured back at Computex worked at 1.6 GHz only. The second trouble is that not all the chips from wafer works and we know that AMD is currently not happy with yields of the chips and will likely need another revision and it can pray that everything including clocks, leakage and speed is going to be fine. Otherwise it won't be pretty.

Most of the Barcelona or Opteron 2200 or at later date Phenom FX CPUs won't actually work at 2.5 or more, they will rather be clocked to modest speed of only 2.0 GHz or lower.

2 GHz is far from being enough to dethrone Core 2 Duo who even at 3.0 GHz sells for around $270 and as we said numerous times Quad core won't bring much versus Dual core. In case it does Intel already has two iterations of 3 GHz or close to 3 GHz (2.93) so the pressure is certainly on DAAMIT.

部分K10，也就是Barcelona能够超越2.6G甚至一路到2.8G以及3GHz，但是他们中的大部分，至少晶圆角落处的CPU无法大幅超越2GHz，甚至更低

AMD的第二个麻烦是并非晶圆上的所有芯片都能正常工作，而地球人都知道良率问题一直令AMD沮丧，他们很可能需要再次修正设计，并且祈祷能够解决包括时钟频率，漏电流和速度在内的所有问题，否则事情就大条了

大部分的Barcelona或者Opteron 2200 以及稍后推出的Phenom FX CPU都不会工作在2.5G或更高，他们可能会被设定为保守的频率，比如2.0GHz，甚至更低

2GHz要把C2D从宝座上拉下来还差得远，后者的3GHz版本甚至只卖$270，而且INtel已经拿出了2款3G或者接近3GHz（2.93)的实物(iterations),所以压力显然在DAMMIT(AMD和ATI的组合,恶搞，谐音DAMN IT)身上

意思是桌面的K10只有2G甚至更低的频率？？？:huh:

良品率的问题，高频率的大概比熊猫多些，但也会有，就是不知道能不能卖的起价格了
另外估计无论高频低频都非常难OC。
著名A粉站fudzilla的消息,可以排除诋毁因素了
当然，U还不是最终版....

jaguard

会出现大批超频极品了

OMG,怎么会这样

advan

反正等着就是了:charles:

高频率的反正也卖不出多少，市场主流还是中端，良品率和功耗才是大问题。

PS：Fudzilla明显是I/N粉，最擅长的就是捧杀AMD，R600如果不是发布前吹的太厉害，现在的名声不会这么差。
