PCMark04: CPU and Memory
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."
Abit's AA8 DuraMAX outpaced the Foxconn 915A01-8EKRS2 by a very small margin in PCMark04's CPU performance module, and both boards were slightly faster than a similarly clocked i875 system. The 76 points separating the top two boards equates to only a 1.5% different, however, which is well within the margin of error 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."
We had a similar result with PCMark04's memory performance module. In this test, the AA8 was again the victor, but again it was by a very small margin. It outpaced the Foxconn board by 91 points, or 1.6%, and both of the i925x boards were again slightly faster then the i875.
