XP and Vista Performance Competition
In the Windows Vista issued to the public before, people test the new version of the beta operating system has attracted wide attention. Compared with the Windows XP, seems to be running Windows Vista will be reduced in performance. Is it true? Or is it just that Microsoft's opponents processing scare tactics?
As we all know is, rather than running Windows XP, running Vista you need a faster computer. Microsoft recommends is at least 1Ghz of CPU and 1GB of memory, and support DirectX9 graphics, so in addition to the Vista Home Basic version, you can run the other version has good effect. I don't want to try to run Vista in the 1 GHz CPU that will only slow it is painful. Therefore, when you configure your new machine, make sure you at least need to have at least two times the recommended configuration memory and CPU speed, there is a 128 MB and above the PCI-Ex16 memory card, that will be better. If your graphics card can support DirectX9, so you should be able to run the aero effect.
Vista should contain a lot of new characteristics, and the overall look to have better effect, all places to let your heart faint excitement. But most people just want their games to be more smooth operation, office application can quickly open and did not block the use of the Internet experience, can do what they can to raise the whip, therefore, if an operating system can only be slow, so why should you upgrade? Below, we will have to make some quick test, to prove or eliminate these rumors.
We have to do is, a high-end machines, then the standard load Windows XP Professional SP2, and then run the standard inspection procedure, then in the standard load Windows Vista Ultimate and do the same test. Image test will use 3DMark06, it is run in DirectX 9 but not write to Vista DirectX 10, therefore, it is not possible to make a real performance, but at present the best we can do, and then test the current 3D software. Although these are artificial test, but they can perform a wide range of test, using 3DMark to simulate the current and future game rendering system, while PCMark can simulate the webpage from rendering 3D performance, 2D image rendering and disk usage, all these can be a perfectly.
Used for testing machine:
CPUIntel Core 2 Duo E6700 Striker Extreme nForce680i SLI memory board ASUS pirate ship TWIN2X6400 2GB Gigabyte DDR-2 GeForce 8800GTX 768MB PCI-Ex16, run SLI x 2 150GB 10000rpm hard disk WD SATA-II power OCZ GameXstream 850W ATX
Obviously, this is indeed more than most home or office computer used by some of the more high-end, but so that it can make us do the test some strength is big, and it is easy to find the difference between the two.

The test results of 3DMark06
Through 3DMark06, we can do 3 tests, one is the use of graphics in SLI mode, one is using only a single card, and another is in the SLI mode using 8 times the anti-aliasing to view, when the 3D system is "tight" situation, whether there are more different. All tests are done in 1280x1024 resolutions.
In the SLI test and single card test, the performance when using Windows XP are about 5% more, although has shown the advantage is very small, but still win XP.
In addition, through the 3DMark, we also see a lot of test project shows great differences between the two operating systems, especially in the Shader test. The performance shows that the simple Vertex Shader test in Vista behind nearly 50%, obtained using XP is 300000000 86000000 vertices per second and Vista is 100000000 to 86000000. Shader particles test showed Vista behind XP 25%, and pixel shader test also behind 15% performance.

3DMark can also enhance the triangle Batch Size test, 8 is the beginning of a triangle, then increased to 32, 128, 512, 2048 triangle, until the last 32768.
This part of the contents of tested per second triangle shows the graphics memory throughput in this area, two is called a. In these tests, the two version of the Windows batch size increases are in very close to the rate, unless the Vista is run, it also implies that in Vista, there is a big problem that memory throughput. Hope this is only because of driver issues, nVidia could in the future be repaired.
