    Benchmark PC: Testing a computer performance

    No need to be an expert to assess the power of a computer ! With benchmark software, you can easily measure the performance of its different components and know if it is well suited to your use.

    • Choose benchmark software
    • Test a computer with Novabench
    • Test a PC or a Mac with Geekbench
    • Test a PC with USERBENCHMARK

    Is your computer powerful enough for your use ? How is it in relation to similar models ? What are its strengths and weaknesses ? Which component to change to improve it ? If you are a little curious and fond of technique, you have certainly already asked yourself these kinds of questions. Especially if you have observed signs of breathlessness in software or game, or after an update of the system, for example.

    However, it is not enough to know the technical sheet or the precise identity of its components to know what a computer really has in the belly: it is necessary to carry out performance tests, as for a car that passes to the bench ! However, no need to have a laboratory, to be an IT expert or to disassemble anything to test the performance of a computer. Indeed, everything can be done in a few minutes using specialized software of benchmark Or benchmarking – In French, comparative performance analysis. Depending on their nature, these tools test all or part of the different computer subsets-processor (CPU), graphic circuit (GPU), RAM (RAM), storage (HDD or SSD), etc. – and synthesize the measurements made with scores and a more or less detailed report. You can easily compare your computer to other models, but also identify its strengths and weaknesses, detect a possible problem – an unsuitable software driver, for example – or even assess the impact of a change – Added RAM , change of graphics card, replacement of a hard drive by an SSD, etc.

    What benchmark software to use ?

    There are many benchmarking tools. If you read technical sheets or hardware tests in the press or on the web, you have certainly already seen performance scores from specialized software such as PCMARK, 3DMARK or SANDRA. Mainly intended for professional use, most of these very complete reference tools are paid. But some are available in free, more limited evaluation versions. And others, like Novabench, Userbenchmark or Cinebench, are completely free.

    The price is not the only differentiating element. Indeed, certain tools like Userbenchmark or 3Dmark only work under Windows, while others like Geekbench or Novabench can also be used under MacOS or Linux. Another important difference, the evaluation mode. Some software focuses on raw performance tests – computing time for processing or file compression, transfer speeds, number of images displayed per second, etc. -, while others simulate current actions to better account for the use of a daily computer. In addition, some push video tests further than others to assess the power of graphic circuits, in particular by assessing the number of images per second (FPS, for Frames per second) reachable in different definitions – an essential criterion for players, since it determines fluidity in gourmet 3D games. In addition, and depending on the method used, the tests are more or less long. Software like Userbenchmark makes a complete assessment of a computer in a handful of minutes so Cinebench takes much more time. Finally, some tools are content to provide scores without appreciation, while others accompany them with comments, advice and comparisons. In short, you will understand, there is something for everyone !

    Be careful however, even if they look alike, do not confuse benchmark software with utilities used to identify the components of a computer like Speecy, Everest, Siw, Belarc Advisor or HWM Blackbox (see our practical sheet identify the components ‘A PC). Admittedly, all give technical information on the different elements (type and frequency of the processor, references of the RAM, etc.), but the benchmarking tools are also carrying out tests. Another detail, most benchmark software is in English. Nothing insurmountable – no need to be bilingual to use them -, but it is better to have a few notions on the technical jargon ..

    To help you assess the performance of your computer, we have used several free benchmark software in this practical sheet, which work more or less on the same principle, but by delivering different results. Nothing prevents you from trying others to find the one that suits you. Note that we have voluntarily excluded the test tool integrated into Windows – which is now well hidden in Windows 10 -, since it only provides abstract indices, without any reference, and that it is used by person. No interest therefore, even if Microsoft’s intention was commendable.

    Whatever the tool chosen, remember to close the other open applications and do not touch anything during tests so as not to distort the results. In some cases – on laptops in particular – it is advisable to change the Windows performance mode to make measurements in an optimal configuration, and not with parameters that favor battery life at the expense of calculation performance.

    How to measure a computer performance with Novabench ?

    Less known than tenors like Pcmark or Cinebench, Novabench is a benchmark tool with several advantages. First, it works as well under Windows as under MacOS or Linux. Then it is extremely easy to use, which makes it usable by everyone. Finally, it is completely free ! For this practical sheet, we used the version for PC under Windows, but the manipulations are identical with a Mac or on a computer with Linux. Admittedly, tests are much less advanced than those of professional solutions, but they are fast and allow you to get a global idea of ​​the performance of a computer.

      With your web browser, go to the Novabench site and download the version of the software adapted to your operating system by clicking on the suitable button or click directly on one of the buttons below.

    • The page that appears reminds you of the scores obtained and indicating the rank of your computer in the section Overall Rank : the more number is high, the more your computer is powerful.

    • If you want to compare your computer to other models, click the menu Overview and select Baseline Comparison. Then click on the menu Compare to .. which appears just below and select a type of configuration from the choices offered: Mid-Level Gaming PC (for for mid -range player), High-End Laptop (high -end portable), etc.

    • The comparison assessment is immediately displayed with positive or negative percentages indicating differences from the chosen computer.

    • To have a more global vision of your computer performance, click on Score & stats, at the top of the web page. A classification by order of decreasing scores obtained by other users, with the details of their configuration is displayed. You can browse it by clicking on the buttons Next And Previous, at the end of the page. You will quickly know if your machine is still in the race !

    How to measure performance of a PC or a Mac with Geekbench ?

    Geekbench is one of the most popular benchmark tools. Very focused on the performance of processors and graphic circuits, it performs fairly advanced, but fast tests. Advantages, it is Windows, MacOS and Linux compatible and it delivers a simple assessment, with a clear score: the higher this number, the more efficient the computer is. Like other tenors on the market, Geekbench is paid software, but it is also available in free trial version, more limited, but sufficient compare a computer to other models.

    • With your web browser, go to the geekbench site then click the button Download, or click directly on one of the buttons below to download the version corresponding to your operating system. .

    • Once the transfer is completed, open the download folder for your computer and double-click the recovered file, Geekbench-5.3.2-WindowsStup.exe In the case of the Windows version for example. The installation window opens. The operation has no particular difficulty: simply click the button Next at each step.

    • At the end of the installation process, let the box checked Run Geekbench and then click on the button Finish To use the software right away.

    • With the test version, each launch, a message is displayed to encourage you to get to the paid version. To get over, just click the button Later.

    • The main geekbench window opens, by displaying some technical information on the computer: operating system, model, motherboard, RAM capacity and processor.

    • At this point, Geekbench offers two types of tests: one for the processor, the other for the graphic part. Click on the button Run cpu benchmark To test the processor.
    • Geekbench then launched a series of tests on the processor, by displaying a window with a progression bar. Wait.

    • When the tests are finished, a tab automatically opens in your web browser to present the results. Geekbench gives two performance scores, one for mono-heart operations (single-core), the other for multi-heart tests (multi-core).

    Scroll again the page down to display the detailed results of the various tests, in the sections Single performance And Multi-core performance.

    • You can then go to the graphic part in the same way in the section Benchmark compute. With one difference. If you have two graphic chips (an integrated type Intel Iris Graphics or AMD Radeon Graphics, for example, and a dedicated card (GeForce GTX, RTX or Radeon type), you can choose which one test by clicking on the menu Compute Device, down. By default, Geekbencj chooses the most powerful circuit.

    • Then click on the button Benchmark compute To launch the graphical circuit performance measurements and wait.

    • Once the test is completed, a tab automatically opens in your web browser to present the results with a score and details.

    How to measure the performance of a PC with USERBENCHMARK ?

    Totally free, USerbenchmark allows you to test a Windows PC in a few minutes, very simply. The software, which does not need to be installed, then generates a full report indicating whether your PC is suitable for office automation, gourmet video games or even very demanding calculations, such as a professional workstation (Workstation, in English). The report can be viewed online, on a web page: it allows many details on the different tests but also to compare your computer to other models of the same category, equipped with identical or similar components, and above all , to see if it is suitable for different uses.

    • With your web browser, go to the Userbenchmark website or click directly on the button below to download the software.

      Once the file has been recovered on your PC, open your download folder and double-click the program Userbenchmark.exe that you have just downloaded. If the Windows user account control window appears to request an authorization, click the button Yes.

    • Userbenchmark then performs a series of tests on the processor, the graphic part, the fixed storage systems (hard disk and SSD) and the RAM. The operation lasts only a few minutes during which various information and images scroll on the screen. Wisely wait until the process is finished, and without using your PC so as not to distort the results.

    • When the evaluation is complete, the mention Enforcement is displayed at the bottom of the test list. Just click the button Closed.

    • The Userbenchmark report then opens automatically in a tab of your web browser.

    • Unlike other benchmark tools, Userbenchmark does not directly provide scores, but adequacy percentages to three main categories of uses: gaming (video game), desktop (office) and Workstation (Station). It also delivers a synthetic ratio on each important subset: Processor (processor), graphics (graphic circuits), boot drive (disc used for start-up), Memory (RAM). The whole is associated with a simple and explicit color code: green when the result is good, orange when it is average, red when it is insufficient.

    • To find out the details of each category, simply click on the small associated question mark.

    In addition to the percentage indicated for each category, Userbenchmark displays a small fancy mention (UFO, Nuclear Submarine, Aircraft Carrier, Battleship, Battle Cruiser, Destroyer, etc.) to classify results. Each category corresponds to a difference of 10%, the UFOs being classified between 100%and 90%, the Nuclear Submarine between 90%and 80%, the Aircraft Carrier between 80%and 70%, etc.

    • Return to the previous page using your web browser’s return arrow to display the evaluation report again.

    • In our example, our test PC obtains a score of 13% for use as a game machine, 78% as a desktop computer and 11% for a workstation. It is therefore well suited to daily use for office automation, web browsing, photos processing, with several applications simultaneously. But it is not recommended to play or do heavy calculations.
    • Userbenchmark also gives an opinion on each element tested: the PC as a whole, the processor, the graphic circuit, the starter disc and the RAM with here again, percentages and a color code.
