XP,Vista,Win7再次对决多核CPU性能

Win7之家（ www.win7china.com）：XP,Vista,Win7再次对决多核CPU性能

 日前，Infoworld就多核处理器性能在Windows XP，Vista和Windows 7之间进行了测试，而结果似乎依然是XP胜出了。

但有趣的是，Vista和Windows 7的得分几乎相同，但在底层上和XP又都是截然不同的。他们分析得出的结果是，如果说XP是个橘子的话，那么Vista和WIndows 7就分别是香蕉和熟透了的香蕉。

另外，他们还指出，与XP相比，Vista和Windows 7针对多核处理器进行了原生优化。最后的结论是，如果不考虑如总线速度，I/O内容和内存延迟等内在因素的话，Vista将会在内核数达到32-64个时，追上XP。而Windows 7则会在内核数达到16-24之间时，赶上XP。也就是说，虽然目前Vista和Windows 7都比XP慢，但几年后，当16核或24核CPU普及时，你们就要感激微软所做的这一切了。

小编：其实测试就是测试，只能当作测试来看。普通消费者们看重的不是这样不知可靠性到底有多高的测试，而是实际的使用体验，因此，到底怎么样，还是得拉出来溜溜，最好是自己试试才知道。

附部分原文：

InfoWorld has a very interesting test between Windows XP, Vista and 7 in terms of multicore performance, and it seems like Windows XP still wins (right now). But there are even more interesting things.

The interesting bit is that, using the testing workloads they came up with, they were able to find that Vista and 7 were almost exactly the same, barring some tweaks, and very different from XP under the hood. Our analogy would be that Windows XP is an orange, and Vista and 7 are a banana and a ripe banana, respectively.
