最后的K8：Athlon 64 X2 6400+实测
面对来势汹汹的Intel Core 2 Duo，AMD K10 Phenom迟迟无法上市，只能依靠K8 Athlon 64 X2苦苦支撑。为保住形势，AMD将在本月20日推出新款Athlon 64 X2 6400+，主频提升至3.2GHz，预计售价220-240美元，定位于Core 2 Duo E6750和E6850之间。
规格方面，Athlon 64 X2 6400+仅仅是主频提高了200MHz，倍频也达到了16x，事实上该型号依然基于90nm Windsor核心，Socket AM2接口，2MB二级缓存，热设计功耗125W，德国德累斯顿Fab 30工厂出品。
值得注意的是，由于目前很多主板都没有预留16x倍频，因此在使用X2 6400+的时候需要刷新BIOS。
这款末代高端产品能否完成自己的使命？以下是来自香港HKEPC的实际测试。
测试平台如下：
处理器：
Intel Core 2 Duo E6850 (3.00GHz/4MB L2/1333MHz FSB)

溫度/功耗測試︰
但对比E6750($183)和E6850($266)，X2 6400+就没有什么优势了。与E6750相比可以说互有胜负、大成平手，但在E6850面前，除了传统强项Science Mark和SiSoftware Sandra内存带宽，X2 6400+全面落败。不过，如果X2 6400+能降价到183美元之下，则在性价比上还有机会挑战对手。

综合看来，AMD要想凭借继续挖掘K8潜力来对抗Intel Core 2 Duo已经不太可能，唯有专心K10 Phenom，早日拿出新品，毕竟，Intel的45nm Penryn也不远了。
