UnixBench has been around for a long time now, and it is a good general-purpose benchmark 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 get lower scores, and it shows this benchmark is not a strong one for the GA-7PESH3.
SPEC CPU2006v1.2 measures compute intensive performance across the system using realistic benchmarks to rate real performance.
When CPU2006 first came out, many complained about how long this benchmark took to run; it could last up to 12 days for a full run. In our tests here, we are seeing runs take a good two full days to run, which shows how much faster CPU architecture is with modern CPUs.
We break the test down into four parts when running in case there is a problem. This way, we do not waste a lot of time doing a run that has issues.
All of our runs are full CPU2006 qualified and could actually be submitted to the SPEC website.
This benchmark has many different commands to use depending on what the user is looking for. For our tests, we used basic commands that run a full test.
Here, you can see the SPEC scores after full runs for Integer (int) and Floating Point (fp) tests. Single-core runs show how fast (speed) a CPU can perform a given task. In the multi-core runs, we set SPEC CPU2006v1.2 to use all threads, and this is a measure of the throughput of the system.
The additional core/threads of this system has a huge impact on performance in these tests and really show the amount of horsepower that a dual-socket system has over a single-socket board
Single-threaded results are still very important, but when you need lots of those to run, moving to a dual-socket setup is the way to go.
We can see that the GA-7PESH3 with E5-2697 V2s takes a very strong lead in multi-threaded benchmarks.
Looking at the results of single-threaded integer runs, we can get an idea of speed at which the Intel Xeon E5-2697 V2s can crunch through the different integer tests. Not all CPUs are equal here, and ones that have a higher speed will generally perform these tests faster. In this case, this is the stock speed of the Intel Xeon E5-2697 V2s. Naturally, using an overclocked system or CPUs with a higher stock speed will generate higher results.
Now we run the test using all 48 threads of the dual-Intel Xeon E5-2697 V2s to measure the throughput of the system. In this test, more cores/threads will have a greater effect on the outcome.
We can see a big difference here using the dual-socket setup with a three to four times performance boost in many cases.
Just like the integer tests, we now run the floating-point tests in single (speed) mode. The lower clock speeds of the Intel Xeon E5-2697 V2s holds this bench back also.
Here, we see the results of the multi-threaded floating-point run that uses all 48 threads of the dual-Intel Xeon E5-2697 V2s. Like the multi-threaded integer test, more cores/threads will have a greater impact on the test.
