Intel Core 2 Extreme QX6700 - Quad-Core Assault
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.
Intel's Core 2 Extreme QX6700 shows itself to be only 25% faster than the Core 2 Duo clock for clock in this test, as we observe comparing E6700 scores to the QX6700. Of course AMD's fastest dual-core processor takes a beating here by all Intel Core 2 CPUs but this isn't anything new, since the Core 2 Duo launch.

"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.
There aren't any mysteries revealed here in Futuremark's PCMark05 Memory performance module. The Core 2 Extreme QX6700 is right on par with an identically clocked Core 2 Duo chip. The variance in the scores is minor and within the test's margin of error.
