PCMark 04 Tests

 

As another quick reference point, we ran the CPU and Memory test modules of Futuremark's PCMark 04.  These test suites run a series of quick scripted routines that comprise many common desktop compute workloads that an average end user would likely invoke at some point in there experience.  Here are some additional details on the tests.

"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 SB77G5 steps into the middle of the pack here, falling just slightly short of our i925XE P4 560 reference system but besting the P4 3.46GHz EE with its higher clock speed.  There is virtually no advantage afforded by the i925XE chipset versus the SB77G5's i875 implementation, at least in this test case.


"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."

In the memory test module we see the main area where the three platforms are differentiated from each other, system memory bandwidth.  The P4 3.46GHz EE and i925XE combination puts up the best score, with its 2MB of integrated L2 cache on board the CPU.  The i925XE and P4 560 reference system comes in second with its 533MHz CAS 3,3,3,8 DDR2 memory offering a tangible but smallish advantage over the SB77G5 and it's i875 chipset, along with 400MHz CAS 2,2,2,5 standard DDR system memory.
