SPEC CPU2006v1.2 measures compute intensive performance across the system using realistic benchmarks to rate real performance.
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.
You can see here 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 thread to measure the throughput of the system.
The additional cores/threads of this system has a huge impact on performance in these tests and really shows 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.
Looking at the results of single-threaded integer runs, we can get an idea of speed at which the Intel Xeon E5-2670s can crunch through the different integer tests. Not all CPUs are equal here, and ones that have a higher speed will perform these tests faster. In this case, this is the stock speed of the Intel Xeon E5-2670s. Naturally, using an overclocked system or CPUs with a higher stock speed will generate higher results.
Now we run the test using all 32 threads of the dual Intel Xeon E5-2670s 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 speed of the Intel Xeon E5-2670s holds this benchmark back.
Here we see the results of the multi-threaded floating-point run that uses all 32 threads of the dual Intel Xeon E5-2670s. Like the multi-threaded integer test, more cores/threads will have a greater impact on the test.
