<P> Intel为了提高中低端的竞争力，在去年8月份推出i865的简化版本：i848P芯片组，从技术参数与Intel官方网站上都可以看出，i848P其实就是865PE的简化版，除了不能提供双通道的支持外，其他功能与865PE基本上都是一样的，只是为了降低成本，把865PE屏蔽了一条内存通道，由双通道改为单通道，内存带宽由6.40GB/秒，降低到3.20GB/秒，最终变成848P芯片组。由此可以看出，i848P是一块性能强劲的低端产品，和i865PE唯一的区别在于单通道和双通道的支持上。</P>
<P> 作为INTEL的强劲对手的VIA也有一款性能和INTEL 848P极其接近的芯片组——PT800，PT800芯片组支持前端总线和Hyper-Threading超线程技术；内存上支持DDR 266/333/400，同时支持AGP 8X，PT800芯片组主板最常见的搭配是北桥 PT800 +南桥 VT8237芯片。VT8237是VT8235的换代产品，功能和性能上要比8235强很多。</P>

<P> VIA声称他们的芯片组具有和拥有的双通道的英特尔i875芯片组一拼的能力。VIA在自己的测试数据当中，资料显示这款芯片组在PC Mark 2002 Pro的内存测试下，比单通道的i875快1.25%；而在3D Mark 2001下，这款芯片组更是比同一款i875芯片组的机器快1.5%。而在游戏“绝地武士Jedi Knight”的测试当中，两款芯片组的表现更是并驾齐驱。而在雷神三Quake III的FPS表现测试下，VIA的PT800芯片组在640x480更大幅领先5%，而到1280x1024时，表现则和使用i875芯片组的机器旗鼓相当。</P>
<P> 隽星的产品线上这两款芯片组的主板都有，同样，我们也拿来做了一个性能对比测试，也许会给您选购主板时提供一点建议。</P>
