UnixBench has been around for a long time now and is a good general-purpose bench to test on Linux systems.
This is a system benchmark and it shows the performance of single-threaded and multi-threaded tasks.
This shows the system indexes after a complete UnixBench run. Here, we get an idea of how much performance gain we get using multi-threaded applications. However, many applications use single threads, so this number is really the base, and a higher clock speed will increase both indexes.
In UnixBench, we can see a very clear winner in the multi-threaded tests.
The single-threaded test shows the performance of a single thread. With these types of tests, CPU architecture and speed are the basis of the score. A higher clock speed will increase these scores and have a greater impact on the results.
In the single-threaded test, the Dhrystone test is the clear leader, showing a very nice increase in the score.
The multi-threaded test uses all 32 threads of the Intel Xeon E5-2670s. In this test, more cores/threads will have a greater impact on the results.
Again, we see the Dhrystone test taking the lead with a nice increase in the score. All other tests here were very close, so the Dhrystone test has the biggest impact on the final score index.
