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 and HyperPi 0.99.
AMD CPUs usually have some issues with memory performance. We can see that here in the graph. This "issue" can cause problems with highly threaded applications that are also memory inefficient or that need large amounts of memory to execute their code (like After Effects).
For general CPU performance the PII X6 1100T does fairly well, until we get to the Crypto testing; here it does bog down a little compared to Intel's new CPUs with the encryption instructions embedded in the CPU.
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.
As with most AMD CPUs, the PII X6 1100T does not do well with HyperPi. We have a feeling that it has to do with the way the caching and memory controller work together, but we have not been able to prove the conclusively yet.
