UnixBench has been around for a long time now and is a good general-purpose benchmark to test on Linux-based systems.
This is a system benchmark and 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 are single threaded, so this number is really the base, and a higher clock speed will increase both indexes.
We can see that the slower clock speeds holds this benchmark back a little, but with 32 threads versus 8 threads, we can see a nice jump in the multi-threaded results.
The single-threaded test shows the performance of a single core. 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.
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.
