UnixBench has been around for a long time now, and is a good general-purpose bench to test on Linux based systems. This is a system benchmark, and it shows the performance of single-threaded and multi-threaded tasks.
Synthetic benchmarks only show part of the performance of a motherboard. When using tests that are more complex, we will start to see a different trend in the scores. UnixBench starts to show what the X10DAi can really do well, and that is multi-threaded workloads.
SPEC CPU2006 v1.2
SPEC CPU2006v1.2 measures compute intensive performance across the system using realistic benchmarks to rate real performance.
In our testing with SPEC CPU2006 we use the following basic commands to run these tests:
Runspec --tune=base --config=tweaktown.cfg; then int, or fp.
To do multi-threaded, we add in --rate=64.
When SPEC CPU first came out, these tests could take up to a week to run, but as computers become faster, our tests now take up to four days for a full run, and even less on some systems. The user can do many thing to effect the results of CPU2006 runs, such as compiler optimizations, add-ons like SmartHeap, and different commands used to start the tests.
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 with a base tune.
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 to measure the throughput of the system.
The additional cores/threads of this system have 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 many single-threaded apps to run, moving to a CPU with more cores is the way to go. This is where the X10DAi starts to shine: multi-threaded interger workloads.
Looking at the results of single-threaded integer runs, we can get an idea of speed at which the E5-2698 v3's 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. Naturally, using an overclocked system, or CPUs with a higher stock speed, will generate higher results.
Now we run the test using all 32 cores/64 threads cores on the E5-2698 v3 processors to measure the throughput of the system. In this test, more cores/threads will have a greater effect on the outcome.
Just like the integer tests, we now run the floating-point tests in single-threaded (speed) mode.
Here we see the results of the multi-core floating-point run that uses all 32 cores/64 threads cores on the E5-2698 v3 processors. Like the multi-threaded integer test, more cores/threads will have a greater impact on the test.
Just like we saw in the integer multi-threaded tests, the X10DAi really takes off here.
