PCMark04: CPU & Memory

In this next round of benchmarks, we ran the CPU and Memory performance modules built into Futuremark's PCMark04 suite.  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."

Considering we used the exact same CPU in all four test systems, we expected all of the systems to perform similarly in PCMark04's CPU performance module. And while the DFI LANPARTY 925X-T2 did take the top spot, its margin of victory was quite small.  There is only a 1.3% performance delta separating the highest and lowest scores in this test.

"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."

PCMark04's memory performance module showed a bit more disparity between the test systems.  Just like we saw with SANDRA, the 925X powered systems, with their higher-clocked DDR2 RAM, nudged slightly ahead of their i875 / DDR1 equipped counterparts.  Once again though, the performance deltas were relatively small, and may not translate into any "real-world" differences in performance.
