I do not like software test that never show a peculiar and extreme use of a machine, they have the advantage of synthesizing a legible results. Legitreview has used such tests to compare performance EeePC 1005HA Windows XP and Windows 7. The site gives very little information on installing itself except that the ACPI management of energy saving machine requires special handling. It is not clear how much of the original software from Asus is present when testing the machine under Windows XP. Still, the result is to the advantage of Windows XP for the autonomy of the machine.

This advantage is low, additional 10 minutes, in IDLE mode where it does not operate the machine. 26 minutes more video playback, but it’s important we do not really know what causes such a change. The software suite, the Super Hybrid Engine, has been installed in the test Windows 7?

If so, if everything has been done in the state of the art, it is a very bad news. The latest generation of machine displaying almost a half-hour autonomy and less with Windows 7, the loss is important for an operating system that will cost more to the user.

On these last there tests of software power and graphics processor, the results are more mixed.. They are sometimes in favor of Windows 7 and other times in favor of XP. These tests are quite unrepresentative of the actual use of a computer by a human being, I think the performance difference will not change much. Perhaps it is indeed the problem, why pay more for an operating system like Windows 7 if the result is the same under Windows XP?

It is still only the beta of Windows 7, not the final system, Microsoft has a few more weeks to improve performance or at least make them in every way equal to those of XP. The additional costs generated by the new version of Windows could then be offset by new services it offers. If this is not the case, it will be difficult to convince manufacturers and buyers of the value thereof.
