This 20% is most likely a special scenario but I'm willing to bet run typical benchmarks and you'll witness probably a complete different story. Vista SP1 scores 500 points lower in 3DMark06 compared to XP SP3 for example, I doubt Win 2k8 would be much better either.

As I promised. I could have done much better but I do not have the time to do it. I have also included the Windows Server 2008 64 Bit as many of you wanted to.

First is the hardware used for the test, before I proceed I have to tell my system was and still acting a bit odd as I'm getting some kind of interference related to some unknown damaged hardware part. So the tests have been run many times to make sure is the real deal/result got.










Programs used:

  • Aquamark
  • Lightmark
  • OpenGL Fur
  • Sandra
    • Memory
      • Bandwidth
      • Latency
        • Linear
        • Random
    • Physical Disk
    • Processor Arithmetic
  • Super PI
  • 3DMark
    • 01
    • 03
    • 05
    • 06




Aquamark:



The numbers have no much difference with the SP3 update, as the results are quite similar.

Lightmarks



As we can see above SP3 leads the performance, SP2 comes quite closer and Windows server 2008 lags really bad on this benchmark.

OpenGL Fur



We can see here that OpenGL is the way to go for Server 2008 users as it is very competitive on this benchmark, no downsides were spotted so far.

Sandra Memory Bandwidth:



Sandra Memory Latency Linear:



Sandra Memory Latency Random:



Sandra Memory Physical Disks:



Sandra Memory Processor Arithmetic:



The most of Sandra tests were quite normal, but one called me attention by the fact it showed a very poor performance, processor arithmetic is really the drawback here. I still have to find the why, in CPU tests ran on 3Dmark using Windows Server 2008 64 bit the processor was far superior than when it was running on XPSP2 or XPSP3.

Super PI

















Conclusions:

So Windows XP SP2 improved its 3D performance once upgraded/with SP3. The Windows Server 2008 ran much better once used the CPU as it contained 64 Bit extension, its weak point is definitely the 3D performance, its strong point was the CPU that has had a superior performance than XP. Although Windows Server 2008 it is highly recommended for DX10 games that are coming within few months. If you hate Vista this is a must have Operational System.

Windows XP got much better and stable but it will be soon not be utilized anymore as Microsoft said that DX10 will be vista and upwards. The real is when the money matters, nothing else comes ahead of it.

The tests will be updated as I get new parts/components. I still think Windows server 2008 64 Bits could have run much better than this. That is why I will be updating the results.
