PCMark05 CPU and Memory Benchmarks
For our next round of synthetic benchmarks, we ran the CPU and Memory performance modules built into Futuremark's PCMark05. For those interested in more than just the graphs, however, we've got a couple of quotes directly 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. 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.
Just like with SANDRA, the PC Mark 2005 scores don't show much of a difference between the two boards. Having said that, we once again we see the AB9 Pro pull slightly ahead of the DQ6. This time by just over 3%.
"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.
Although SANDRA showed the AB9 Pro as a bit faster when it comes to memory, PC Mark 2005 has both boards posting nearly identical numbers. This isn't surprising since both boards were configured with identical DDR2-800 modules set to 4-4-4-12-1T timings. Once again the AB9 Pro beats the DQ6 ever so slightly.
