CPU - Prime98 - wasn't developed as CPU test though, so GUI is "different"
Prime95 offers to perform a torture test right off the bat. The torture test is ideal for testing the stability and heat output of your CPU, and is particularly useful if you’ve overclocked it. If you want to perform a torture test, go ahead and click the “OK” button. Note that the torture test can take quite a while to run. If you just want to perform a benchmark instead, click the “Cancel” button.
You can run a benchmark by opening the “Options” menu and then clicking the “Benchmark” option.
