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.
Foxconn squeaks by for the win here, but unfortunately drops quite a bit when we overclocked the system This is interesting as we had the memory pushed to 1600MHz, yet we still see a drop in performance of just over 1GB/s.
Everest Ultimate is a suite of tests and utilities that can be used for system diagnostics and testing. For our purposes here we use their memory bandwidth test and see what the theoretical performance is.
Ok, I am not sure how to read this one; in our Sandra testing we saw a drop in performance. However, in Everest we see an increase in available bandwidth and the memory clock is showing 1600MHz. Still, it does look like you are not really losing any memory performance when you overclock 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.
The Foxconn A9DA-S does an excellent job here; both the stock and the overclocked times are better than the competition. Unfortunately it is still not enough to catch the H57+ Core i5 661 system, though.
