With any system you will want to see a combination of synthetic testing and real-world. Synthetics give you a static, easily repeatable testing method that can be compared across multiple platforms. For our synthetic tests we use Everest Ultimate, Sisoft Sandra, FutureMark's 3DMark Vantage and PCMark Vantage, Cinebench as well as HyperPi. Each of these covers a different aspect of performance or a different angle of a certain type of performance.
Memory is a big part of current system performance. In most systems slow or flakey memory performance will impact almost every type of application you run. To test memory we use a combination of Sisoft Sandra, Everest and HyperPi 0.99.
The RIIIF has some very impressive stock memory scores. It manages to jump ahead of the rest of the group by a decent margin. During the overclocking testing the RIIIF dropped back quite a bit. Of course, we cannot put too much stock in that because every overclock is different. Still, we do wonder why the drop in score is here as it did not seem to have any issues with memory when we pushed it.
Replacing Everest in our labs is AIDA64. This new testing suite is from the core development team from Lavalys and continues that tradition. The guys have thrown in better support for multithreaded CPUs as well as full 64 bit support. We use this to test memory and HDDs for now, but may find ourselves opening this up to other areas of the motherboard.
Here we find a discrepancy; the Sandra score shows us losing speed when overclocked while AIDA64 shows the opposite. We will need to keep an eye out on the rest of the scores to see if we can verify one score or the other. We are certainly hoping that the AIDA64 scores are accurate.
HyperPi is a front end for SuperPi that allows for multiple concurrent instances of SuperPi to be run on each core recognized by the system. It is very dependent on CPU to memory to HDD speed. The faster these components, the faster it is able to figure out the number Pi to the selected length.
For our testing we use the 32M run. This means that each of the four physical and four logical cores for the i7 and the four physical cores of the i5 is trying to calculate the number Pi out to 32 million decimal places. Each "run" is a comparative to ensure accuracy and any stability or performance issues in the loop mentioned above will cause errors in calculation.
The HyperPi score at stock speed is great. Unfortunately the overclocked score points to something that might not be good news. It is more in line with the Sandra scores than with the AIDA64 scores. However, this is only one test; we will have to see what the rest of the scores show.
