Bearlake芯片组又悄然无声的被P45/P43取代，当习惯了更新芯片组速度的时候，更加关心的就是更新后，新的芯片组主板价格问题。是否过高或是有BUG等等。但P45芯片组更新来的相对较快，比起P35来说。至少从评测角度来说P45的到来就是一些芯片规格的变化，更新了一些必须要更新的
最强P43主板非他莫属
Bearlake芯片组又悄然无声的被P45/P43取代，当习惯了更新芯片组速度的时候，更加关心的就是更新后，新的芯片组主板价格问题。是否过高或是有BUG等等。但P45芯片组更新来的相对较快，比起P35来说。至少从评测角度来说P45的到来就是一些芯片规格的变化，更新了一些必须要更新的规格，如：PCI-E终于做到了2.0规格，南桥用上了ICH10......比起P35更替P965来说P45变化还是相当“大”地。对于芯片组变化这里先不多说，我们评测室近期也收到了很多P43的主板，Kevin同学也刚刚完成一篇文章《全球首款 七彩虹P43蓝牙主板评测》。而今天K男带来的就是另外一款来自ASRock（华擎）的P43，型号为P43R1600Twins-WiFi。而这款来自华擎的P43主板，延续了华擎4Core1600P35-WiFi主板的设计特点，如：FSB支持到1600，同时支持DDR2跟DDR3内存，支持WiFi 802.11g的无线网卡，还有整个主板使用了全固态电容设计，个人觉得不比P45逊色多少，甚至会让一些号称P45的主板汗颜。

而这款来自华擎的P43主板，延续了华擎4Core1600P35-WiFi主板的设计特点，如：FSB支持到1600，同时支持DDR2跟DDR3内存，支持WiFi 802.11g的无线网卡，还有整个主板使用了全固态电容设计，个人觉得不比P45逊色多少，甚至会让一些号称P45的主板汗颜。作为普通消费者来说最适合的就是最好的，七彩虹的P43主板上设计了蓝牙模块，今天的华擎P43R1600Twins-WiFi功能上更多，规格来说更高一些。也说明大家在主板设计上不再居于同质化，这点作为普通消费者来说更加实惠，好了不多说了，回到正题开始评测。
