处理器大厂AMD今日在Computex Taipei 2005上发表双核心桌上型芯片，而包括宏碁、HP及联想集团等计算机大厂均表示将快速推出基于新处理器的电脑产品。

在Computex 2005大会上，AMD发表了四款双核心Athlon 64 x2处理器，包括4800+、4600+、4400+及4200+等。AMD宣称双核心心产品比原有产品速度大有提升。以4200+为例，其速度就比原有最快的单核Athlon产品64 4000+快10%。4800+则要快22%。

新产品速度惊人，但规格繁杂：4800+与4600+两款都具有2.4GHz的时钟速度，但4800+的L2 CACHE为1MB，较4600+大一倍。而4400+及4200+时钟速度为2.2GHz，L2 CACHE为1MB及512KB。他们的竞争对手Pentium D的时钟速度则在3GHz左右。

AMD宣布4800+的芯片单颗售价为1,100美元，4600+为803美元，4400+及4200+各为581及538美元。远比现有的Athlon 64昂贵。也比竞争对手的双核心产品Pentium D要贵，Pentium D单颗售价在241到530美元间。
