Recently, Microsoft has officially released Windows 7 (hereinafter referred to as Win 7) operating system. Although the self-test version of the beginning, Win 7 to be recognized and sought after many users, but according to our for Windows XP (hereinafter referred to as XP) user survey, there are still nearly 6 percent of the XP users to upgrade Win 7 on the sidelines even explicitly said they did not consider upgrading. One major reason is the upgraded performance problems that may arise concerns. Then the same configuration of the computer after installation of Win 7, the performance will not reduce it in the end?
so many users may Win 7 But with the XP operating system, eight-year history has never been recognized by the majority of users, while Vista's Then the same configuration, XP after upgrade to Win 7, in the end performance? In this paper,Microsoft Office Professional 2007, the current mainstream configuration of a computer in XP and Win 7, respectively, the daily application behavior for key performance parameters involved were compared with tests in order to be able to give you a reference.
demand for more memory footprint Win 7

system memory usage is the application of the system is running an important factor, but also our first choice for comparison reasons. Under conditions with limited memory, the memory system, the less memory left to application software the more the better application performance. However, if the memory is large enough, the system memory usage will generally not a problem.
them in XP, the system's memory footprint is automatically assigned, usually accounts for about 15% of physical memory, therefore, 2GB of memory system takes about 300MB, it's with this actual test results good agreement (as shown in Figure 1, upper half). In the Win 7, the actual test system memory footprint of about 540MB, XP system occupies nearly 1.8 times (as shown in Figure 1, lower half). Win 7 shows memory requirements for the relatively higher.


relative to 2GB of memory for, Win 7 of this extra 240MB of memory, the system performance and other software applications do not have much impact. However, if the computer itself is relatively low memory configuration, coupled with some of the more you want to run memory-intensive software, then application performance will be reflected on the obvious gap. 1GB memory to run Photoshop CS3, for example, software running on the independent memory to be occupied by more than 100MB, and open the three normal size photos, and perform certain operation, takes about 300MB of memory will have a direct rise. To get rid of the memory required to run (XP about 150MB, Win 7 of about 300MB), then run Win 7 large-scale software like Photoshop that will be relatively slow.
to configure Microsoft's official minimum standard 1GB of memory, in application performance, XP system, the system better than the Win 7.
test results: a memory capacity of 2GB or more users to upgrade Win 7, the software does not affect the application performance. As for the memory capacity of less than 2GB, and often with large software users, continue to use XP operating system or adding memory is the better choice.
basic application was no clear winner

In theory, if the operating system itself is not a problem and does not take up too much of the hardware resources, then the same hardware in different operating systems performance should be similar . Therefore, we use a more authoritative SiSoftware Sandra systems analysis tools, testing the same hardware platform in Win 7 and the main performance under XP and see if the same hardware in XP and Win 7 in what will be the performance.
by comparing data in the table we can see that the five test data XP Win 7 and the outcome of each other, but overall performance is similar, also in line with our earlier theoretical analysis.
performance in such a subtle difference, in practical application, the user will not have any feeling. For example,Microsoft Office 2007 Key, in using Excel for a lot of data operations, if required under 5 seconds in XP to complete, then under the Win 7 is 5.05 seconds to complete; use of OpenGL-accelerated Photoshop rendering open a picture, if under 7 seconds in XP minutes to complete, then there may need to Win 7 6.9 seconds to complete.
Test Conclusion: Win 7 for hardware compatibility is worthy of recognition, but also since the release of Win 7 from the acclaimed important reasons. From the test results, Microsoft claims that Mainstream applications in Win 7 of which can be guaranteed.
same time, as Microsoft's most important products a decade,Office Professional 2007, with the increased penetration Win 7, software and hardware compatibility will also not be a problem.


games vary

a major application as a computer game is no doubt that the majority of users are more concerned about. Here we first 3Dmark 06 games on the system when running Direct3D 9C compare the performance test.
data from the table you can see, Win 7 in the total score on the behind XP 1% or so, then this 1% does that mean? For example, if the XP in the play frame rate is 60FPS, then in Win 7 is 59.4FPS. Obviously, such a subtle difference to our game experience will not be any trouble.
In fact, the performance comes to gaming, XP is a clear advantage is the current mainstream games which can run smoothly in XP, but there were a number of Win 7 can not run. Such as
Win 7, but also has its own advantages,Windows 7 Pro, that is, Win 7 support for XP does not support DirectX 10 and DirectX 11, on the effect of speaking, which certainly is better than XP's DirectX 9. And no doubt the future of the game also will Win 7 as the standard, more support for DirectX 11 or later, but apparently that time gaming experience is Win 7 better.
Test Conclusion: For the part of the game is probably the compatibility of Win 7 can not be solved within a short time, because it requires game makers release patches or updates to upgrade the game, so that it can run on Win 7 were normal. So for the play-based users, according to their own circumstances into account whether the upgrade to Win 7. If your favorite game in Win 7 of which can operate normally while the system wants to get better control experience, consider upgrading, or to continue to use XP.


recommended

Win 7 beautiful design interface and full of humane mode of operation allows the user to obtain more excellent than the XP experience, it is proposed as follows .
configuration for a mainstream computer users who upgrade to Win 7 is not a problem;
to buy computers for the older, some parts did not support Win 7 drive XP users, as long as the application to meet the daily demand,Windows 7 Ultimate, it is recommended to continue to use XP, if not satisfied, you can consider upgrading the computer or re-purchase of computer and operating system installed directly Win 7;
limitations for the need to use more professional software (example: tax control software) XP users, it is recommended to continue using XP;
for less than 2GB of memory capacity and the frequent use of large-scale software XP users, recommended to continue using XP or upgrade the memory and then upgrade to Win 7;
other types of user, you can refer to the above test results, arranged according to their own actual conditions.
