Core 2 Duo working better under XP or Vista?

Scope · 7 Jan 2008 at 14:06

I built a Core 2 Duo (6600) machine last year, but has not been impressed by its 2 cores. I can see both in XP, and it does use both cores to a certain degree, but when I run a heavy application (say video encoding) it will run one of the cores at 100%, and leave the other one empty for other things.. I was kinda hoping it would use both so that running a video encode would result in both being 100% busy.

Now to the question; Does dual core CPUs work the same under XP and Vista? Will I gain any performance by switching from XP to Vista? Or do I just have to sit tight for Duo core compatible applications?

it would depend on the program you use for encoding iam afread..

It's all down to the programme you're using. Maybe see if you can get an update for it

It's not just the program - it's the codec. Not all codecs are SMP.

The newest x264 and xvid builds are multithreaded, you just need to update your apps/codecs

What application/codecs are you using?
