PCMark CPU And Memory Testing

For our next round of synthetic benchmarks, we ran the CPU and memory performance modules built into Futuremark's PCMark05 suite.

"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.


There really isn't much of a story to tell here.  Perhaps it's time to finally retire PCMark05 from our test suite.  The CPU performance module shows a keen sense of the obvious.  Like processor clock speeds equate to similar performance metrics.

"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.


Our PCMark memory performance tests at least correlated with what we saw in our SANDRA bandwidth, though the spread in the field was much tighter.  A smallish 2% advantage is afforded to the Asus built P35 motherboard and Corsair DDR3 memory at 1333MHz, versus DDR2 memory on the same chipset.  Additionally, PCMark doesn't show the P35 chipset with much of a lead over the P965 at like speeds and memory configurations.
