AMD

顶级3.2GHz主频Athlon64 X2 6400+首测

由于AM2+处理器的内存频率是按照核心频率作出除频，因此Athlon 64 X2 6000+在正常情况下，DDR2-800模式仅会以DDR2-750速度运作(CPU/8 x 2)，而Athlon 64 X2 6400+则运作于完整的DDR2-800速度，因此在内存测试或是重于内存效能的测试，Athlon 64 X2 6400+将会有较明显的增长。

　　根据AMD向通路商发布的预定售价，Athlon 64 X2 6400+每千颗单价约为220-240美元，介于Intel Core 2 Duo E6850(\$266 PKUP)及E6750(\$183 PKUP)定价之间，故HKEPC编辑部亦找来这两颗处理器作效能对比参照。

　　尽管AMD Athlon 64 X2 6400+核心频率高达3.2GHz，但其效能相较2.66GHz的Core 2 Duo E6750亦有力不从心之感，其除传统强项Sicence Mark 2.0有亮眼表现外，真实游戏测试、Excel Marco宏运算均远落后Core 2 Duo E6750，更遑论欲与Core 2 Duo E6850同场较劲。

　　不过，Athlon 64 X2 6400+售价若能调降至每千颗单价约\$183美元或以下水平，或许还有挑战Core 2 Duo E6850的机会。

　　另外，不单止在效能上，AMD Athlon 64 X2 6400+表现较为逊色外，在处理器功耗及温度表现方面，亦与65奈米、65W TDP的Core 2 Duo E6850有显著差距，看来在K10上阵前，Athlon64 X2 6400+捍卫效能级市场的任务恐怕要失职了。

　　后记︰

　　现时AMD 秘密武器Athlon 64 X2 6400+表现，不及Intel Core 2 Duo E6750、E6850已是事实，完全压制Intel效能级产品销售已是不可能任务，反而AMD要担忧的是，在性价比屈居下风劣势下，极有可能成为英特尔抨击焦点，适得其反成为拉抬对手买气的催化剂。因此，与其献丑不如藏拙，专注K10的制程微调，令核心频率得以提升，赶及上市时程才是王道。

　　曾为AMD拿下全球x86桌面处理器近3成市占的K8架构，面对性能强劲的Intel Core 2处理器已完全显露疲态、无力抵御，尽管进一步拉升频率，也无法弥补效能差距，亦造成功耗大幅增加情况，如同当年Intel Pentium D惨遭Athlon 64 X2打败的翻版，正是前江后浪推前浪，是永恒不变的定律，AMD只有等待K10来临，才能化解陷入连续四季的严重亏损及股价大幅下滑窘境。
