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."
From this point forward, we'll be comparing the Asus A8V Deluxe (K8T800 Pro), to the MSI MS-6702E (K8T800 Pro), and the Asus SK8N (Socket 940 / nForce3 150). We've also added a set of numbers while using the MSI board powered by an Athlon 64 3800+. As you can see, in PCMark04's CPU test, the A8V and MS-6702E performed at near identical levels, with the nForce3 powered SK8N finishing a few percentage points behind.
"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 Asus A8V Deluxe took the lead in PCMark04's memory performance module, but the MSI MS-6702E wasn't very far behind. Only 15 points separated the first and second place finishers in this test. While powered by an A64 3800+, the MSI board finished third, followed by the SK8N. So far, at least according to some synthetic tests, it seems that the VIA K8T800 Pro (A8V & MSI) has a slightly more efficient memory bus than the nForce3 (SK8N). Let's see if the real-world tests tell the same story...
