Testing the performance and authenticity of CPU with software2004-02-05 Author: Tiger Qiu Studio: 11611 reading

For the entire computer, the weight of the CPU speaks for itself.The quality and performance of CPU are directly related to thespeed of the system. In most cases, it has almost become aspokesperson for the level of the machine. But there are a lotof profiteers shoddy, although experience of readers can bedirectly identif ied by the hardware, but for ordinary computerDIY is out of the question. However, we can use the followingtool software to identify the authenticity and performance ofvarious types of CPU.

I. CPU authenticity identification

Good traders will by means of re grinding CPU fraud, and evensome false means very clever, the naked eye is difficult toidentify. This time, software is the best identification, theauthenticity of the identification of master CPU software, suchas WhatCPUIs, Hwinfo, CPU, Stability Test and Sisoft Sandra2003, because the space here to WhatCPUIs and Hwinfo as anexample to illustrate the testing method.

1. WhatCPUIs

WhatCPUIs is an application that specializes in testing CPU andcan run in Windows, 95/98/2000, and NT4 environments. After the

software is installed, you will add a"WhatCPUIs" icon to yourcontrol panel, which you can run with just double clicking onthis icon. It can measure your CPU type, manufacturer, MMXsupport, internal processor clock, and some other functionalsupport for CPU, as shown in figure 1. If your CPU is PIII' sIntel processor, it can also display the internal serial numberof processors (select "Advanced/Page2/Processor SerialNumber") , with no characteristics, will be red. Select theSystem tab, which gives you the general information about theoperating system and network, and also gives the networkaddresses of different CPU manufacturers.

2. Hwinfo

This is a veteran integrated testing software for hardware. Inorder to ensure the correctness of the test results, using thebest in a pure DOS environment (in fact, it is also convenientfor us to test those who have not installed Windows computersystem, CPU) test information is just one of the functions, runthe application, choose "Info/Mainboard Info" menu item, willgive the whole system all kinds of information, the CPUinformation for the front two. Move the cursor to "MainProcessor" and "Math Co-Processor" to return the car. Furtherdetails will be given. Select the "Benchmark/CPU benchmark"menu item, and you can also compare the performance speed ofvarious CPU.

3. Sisoft Sandra 2003

Sisoft Sandra 2003 is a popular, all round testing software thatallows us to detect, view, and, of course, all the information

about all the hardware in the system, including CPU.

Select "View" menu command "Information Modules", or click onthe Toolbar"Switch module view" icon, select the "InformationModules" to switch to the main window information module view.Double click the CPU& BIOS Information module to pop up thedialog shown in Figure 2, which shows details of the CPU, FPU,coprocessor, cache, BIOS, and other related devices found inthe Sisoft system. Here you can see whether your beloved CPUis really like the computer dealer said that model, have youbeen deceived?.

Two, CPU performance testing

Due to the use of different executive engines and system bustechnologies, each processor has a fundamental difference inperforming floating-point and integer operations. WhenchoosingCPU, it is important to test the simplicity of the CPUcomputation. There are also many software tests for CPUperformance,

如Super PI、 SiSoft桑德拉2002、 内容创建2001、 sysmark2000、3DMark 2001等在这里我们以Super PI和SiSoft桑德拉2002为例讲解CPU的测试方法。

1、 Super Pi

Super PI的测试原理非常简单就是利用CPU的浮点运算能力来计算出π 圆周率 目前已普遍被超频玩家用作测试系统稳定性以及测试计算特定位数圆周率所需的时间的工具以此来辨别CPU CPU的性能差别。

运行Super PI后就得到图3所示的界面选择主菜单中”开始计算” 然后点击小三角形符号选择你需要进行的计算位数一般选择104万位就行了。

待计算机运行结束以后我们就可以看到测试结果。如图4所示比如显示了本次计算机104万位圆周率所花的时间是8分27秒依此可判断、 比较计算机内存、 CPU性能以及其稳定性。

2。 SiSoft桑德拉2003

SiSoft桑德拉2003内置了基准的测试内核可以测试你的系统包括CPU、主板、 B IOS、 内存、驱动器、 、 DVD-ROM光盘等硬件。 S i So ft是基于比较的测试软件可以让你了解CPU相对的性能水平是一款简单有效的软件只要双击某个测试子模块等待一段时间就会显示一个测试数据和对照表 SiSoft会将你的系统分值测试的结果用图示的方法与其它典型的系统进行比较使得你对自己的系统性能是处在一个怎样的级别一目了然所以它受到越来越多评测人的喜欢下面我们看看用SiSoft如何测试CPU。

选择SiSoft主菜单中的“视图”菜单里的命令“标杆管理模块” 或者点击工具条上的”开关模块视图”图标选择其中的“标杆管理模块”项可以把主界面窗口切换到分值测试类模块视图。 鼠标双击CPU运算基准”模块即可进行CPU的整数运算和浮点运算分值测试。测试过程有点慢等待一段时间后就会得出一个测试数据和对照表如图5所示。

最开始SiSoft会自动根据用户本机的CPU CPU进行对比测试选择几种标准的。用户也可以根据自己CPU的主频进行更改选择如果用户的CPU CPU相同或相近主频正好给某个给定的可以在其中某一项选择它这样你就可以进行本机CPU CPU的比较与标准看自己是否买

到真货。图5中第一组两行数据是被测的数据下面四组数据是标准CPU CPU数据。

双击” CPU的多媒体基准”图标可进行CPU的多媒体性能测试S iSoft会分别针对MMX SSE和、 3DNow等不同的CPU指令集进行测试这样用户可以对自己CPU的多媒体运算性能有一个深入的了解。测试结果如图6所示。

至于CPU的3d性能我们可以通过3DMark 2001软件来进行测试不过其测试结果与显卡有密切关系。

最后需要提醒大家注意的是一定要给测试软件一个干净的环境在测试前一定要将所有的系统自启动程序关闭如各种实时防病毒软件、个人防火墙超级解霸的播放探测器等否则测试成绩会有偏差不利于你判断其性能好坏。
