For our next set of benchmarks, we ran the CPU and Memory performance modules built-into Futuremark's PCMark04. For those interested in more than just the graphs, we've got a couple of quotes from Futuremark that explain exactly what these tests do and how they work...
"The CPU test suite is a collection of tests that are run to isolate the performance of the CPU. There are nine tests in all. Two pairs of tests are run multithreaded - each test in the pair is run in its own thread. The remaining five tests are run single threaded. These tests include such functions as file encryption, decryption, compression and decompression, grammar check, audio conversion, WMV and DivX video compression."
The PCMark04 CPU testing was really close with a difference of only eight points making it too close to call. The SB95P hung right alongside EPoX's enthusiast-class 5LWA+ without a problem.
"TheMemory test suite is a collection of tests that isolate the performance of the memory subsystem. The memory subsystem consists of various devices on the PC. This includes the main memory, the CPU internal cache (known as the L1 cache) and the external cache (known as the L2 cache). As it is difficult to find applications that only stress the memory, we explicitly developed a set of tests geared for this purpose. The tests are written in C++ and assembly. They include: Reading data blocks from memory, Writing data blocks to memory performing copy operations on data blocks, random access to data items and latency testing."
The memory scores were just as close, only in reverse order. In this test, the Shuttle SB95P just beat out the Epox 5LWA+ by 22 points, but again this difference is so minimal the two systems can be considered equals. It remains to be seen whether this parity will remain throughout the rest of our testing.
