PCMark05: CPU and Memory
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.
Despite having double the number of cores at its disposal - a 100% increase - the V8 rig didn't muster a score all that much higher than the QX6800. Technically, the V8 rig was the fastest of the bunch here, but it's 210+ point margin of victory equiates to only an 2.2% advantage.

"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.
Remember that higher latency we talked about a few pages back? Well it reared its ugly head in PCMark05's memory performance module, where the dual-Xeon V8 rig couldn't keep up with the QX6800 powered system.
