PCMark04: CPU & Memory

For our next round of benchmarks, we ran the CPU and Memory performance modules built-into Futuremark's "all-in-one" benchmark, 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 benchmark put the Shuttle SB81P a hair behind the Abit AA8 DuraMAX, but a few points ahead of the i875 / 3.4GHz Prescott based system.  98 point performance delta separating the fastest from the slowest systems in this benchmark, however, falls well within the margin of error for 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."

The memory performance test built-into PCMark04 had the Shuttle SB81P finishing third here, just a bit behind the DDR1 equipped i875 based test system.  The DDR2 equipped Abit AA8 DuraMAX, however, scored 182 points higher then the SB81P, which equates to roughly a 3.5% performance advantage.
