PCMark05 Comparisons

For our next round of synthetic benchmarks, we ran the CPU and Memory performance modules built into Futuremark's brand new PCMark05. In the course of working with PCMark05 we have found it to be even more robust in terms of test features than its predecessor. That said, the CPU and Memory test modules we use for comparison are very similar to the '04 version of the test suite. For those interested in more than just the graphs, we've got a couple of quotes directly from Futuremark that explain exactly what these tests do, and how they work:
"The CPU 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.
Proving our point from the previous page, the same Pentium 550 is running 100-150 points higher when installed into the G1975X than in the nForce4-SLI and 955X boards.

"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.
The i975X chipset is expected to reduce memory latencies slightly, and PCMark05's memory scores have the G1975X running just a hair over the rest of the boards At best, this is roughly a single percentage point better than that of the others, so it's really not much to rave about.
