Over 100,000 Computers Tested - Updated Daily!

PassMark Software has delved into the thousands of PC benchmark results that PerformanceTest users have posted to its web site and produced lists of the very best and the very worst overall computer systems submitted. Our data covers machines that have a variety of component configurations and operating systems such as Windows XP, Windows Vista, Windows Server 2008 and the latest OS from Microsoft - Windows 7. Click the images below to see the results of these systems and what components they had installed.

Understanding The PassMark Rating

The benchmark score we use to rank PCs is known as The PassMark Rating, which is obtained by users after running the full suite of tests available from PerformanceTest. The PassMark Rating is a unique performance rating for a machine's configuration and is calculated from a machine's performance over six test suites, comprised of twenty-eight unique tests designed to cover all aspects of computing performance.

More specifically, the PassMark Rating is calculated from a series of weighted averages, where some system components are considered to be more critical to system performance based on "average" computer usage. Our rating is also calculated in such a way that all computer components must be performing well in order for the final result to be exceptional - that is, a single extremely high value for one component will not significantly improve the final PassMark Rating.

PCs with a bigger PassMark Rating score are considered to be faster and better performing computers overall. For example, an Intel Pentium 4 3.20GHz may have a PassMark Rating of about 700, while a Core2 Duo E8500 with 3GB of RAM may have a PassMark Rating around 1250.

What Components Will Improve My PassMark Rating?

From our collection of baselines, we've observed that high performance computer systems commonly:

• Run multi-core CPU configurations: CPUs with multiple physical cores provide extra processing performance for top end computer servers and premium PC gaming rigs alike. CPUs that perform exceptionally well in our charts include Intel CPUs such as the Intel Xeon, Intel Core i7 and Intel Core2 and AMD CPUs such as the AMD Phenom and AMD Opteron;
• Use Hard Disk Drives with greater RPM values: Newer technologies like solid state Hard Disk Drives can markedly improve overall computer system performance by improving data storage and retrieval speeds. Hard drive brands that feature strongly on our top 20 systems list include Intel, Seagate, Western Digital, Samsung, Maxtor and Hitachi.
• Use a high performance graphics card: High quality video cards improve overall system performance for many computing activities such as PC gaming, video editing and software development. Modern ATI video cards (such as the ATI Radeon HD) and nVidia graphics cards (such as the nVidia GTX and nVidia Quadro FX) are strongly represented on our top 20 systems list.

How to Add Your Own System

Download and install the latest version of PerformanceTest
Start PerformanceTest then from the menu bar select "Tests -> Run All Tests".
Once the tests have been run, select "Baseline -> Upload Baseline to Web".

As we only update this page once a day, please note that your machine may not immediately appear on our Top/Bottom PassMark Rating charts. Baseline files can also be downloaded from within PerformanceTest
