PCMark05: CPU & Memory
For our next round of synthetic benchmarks, we ran the CPU and Memory performance modules built into Futuremark's brand-new PCMark05 benchmark suite. Below is a brief description from FuturemMark on just what these modules run and measure in terms of performance metrics.
"The CPU test suite is a collection of tests that are run to isolate the performance of the CPU. The CPU Test Suite also includes multithreading: two of the test scenarios are run multithreaded; the other including two simultaneous tests and the other running four tests simultaneously. The remaining six tests are run single threaded. Operations include File Compression/Decompression, Encryption/Decryption, Image Decompression, and Audio Compression" - Courtesy FutureMark Corp.
So what does the above test tell us? Well, in short, an Athlon 64 FX-53 runs about the same on any nForce 4 SLI-based chipset board. the MSI board lagged the three ASUS boards by a hair, but the differential is minuscule.
"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." - Courtesy FutureMark Corp.
We've specifically had issues getting the A8N SLI Deluxe version board to complete PCMark04 and PCMark05's memory test module, which is why you see the "WNR" for "would not run" in this chart. Beyond that again, both of the other A8N series boards put up nearly identical scores, leaving the MSI K8N Neo4 slightly behind by less than 3%.
