PCMark04: CPU & Memory Tests
For our next round 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."
PCMark04's CPU performance module didn't show much of a difference between the systems. The Soltek QBic EQ3901-300P finished in the third slot here, but the performance delta separating the fastest and slowest systems here was negligible.
"The Memory 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 performance modules didn't show much variation either. The MSI K8T Neo2-FIR finished slightly ahead of the pack, followed by the WinFast board, and then the EQ3901-300P. Less than 100 points (1.6%) separated the first and last place finishers though. A difference that small falls within the margin of error in this test.
