Windows XP, Vista and 7 Tested For Multicore Performance, XP Still Wins For Now

Illustration for article titled Windows XP, Vista and 7 Tested For Multicore Performance, XP Still Wins For Now

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.

Another point Infoworld brought up is that both Vista and 7 are actually more optimized for multicore performance than XP, naturally.

Taken to its logical conclusion — and disregarding for the moment external factors, like bus speeds, I/O contention, and memory latency — Vista would ultimately overtake XP when the core count reaches between 32 and 64.

And in Windows 7, they suggest that it will overtake Windows XP at around 16 or 24 cores. So although it may be slower now, in a few years, when you have 16 or 24 cores, you're going to be thankful for Microsoft for their work. But until then, Ballmer can expect lots of angry fist shaking. [Infoworld via Slashdot]

DISCUSSION

I don't understand all the excitement over 7. The interface improvements are interesting, but I don't see them affecting my workflow at all. I installed the x64 beta and between Vista x64 and 7 x64 I could see virtually no difference. My Vista install is six months old too. I never understood the Vista hatred as I've used it with no problems for quite a while. I use CAD programs, Photoshop, and play games on occasion. I watch Blu-Ray movies and I program. My hardware cost about $900. I'm waiting to see what's different when the final release comes out but as far as I can tell this is a slightly improved Vista with a different name. I don't plan on getting a new operating system until WinFS is implemented, otherwise we're just seeing cosmetic changes to basically Vista.
