Win7之家www.airtaxifl.com):XP,Vista,Win7再次對決多核CPU性能

 日前,Infoworld就多核處理器性能在Windows XP,Vista和Windows 7之間進(jìn)行了測試,而結(jié)果似乎依然是XP勝出了。

但有趣的是,Vista和Windows 7的得分幾乎相同,但在底層上和XP又都是截然不同的。他們分析得出的結(jié)果是,如果說XP是個橘子的話,那么Vista和WIndows 7就分別是香蕉和熟透了的香蕉。

另外,他們還指出,與XP相比,Vista和Windows 7針對多核處理器進(jìn)行了原生優(yōu)化。最后的結(jié)論是,如果不考慮如總線速度,I/O內(nèi)容和內(nèi)存延遲等內(nèi)在因素的話,Vista將會在內(nèi)核數(shù)達(dá)到32-64個時,追上XP。而Windows 7則會在內(nèi)核數(shù)達(dá)到16-24之間時,趕上XP。也就是說,雖然目前Vista和Windows 7都比XP慢,但幾年后,當(dāng)16核或24核CPU普及時,你們就要感激微軟所做的這一切了。

小編:其實(shí)測試就是測試,只能當(dāng)作測試來看。普通消費(fèi)者們看重的不是這樣不知可靠性到底有多高的測試,而是實(shí)際的使用體驗,因此,到底怎么樣,還是得拉出來溜溜,最好是自己試試才知道。

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.
