Intel Core 2 Duo E6750 Performance And Overclocking
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.
The upcoming Core 2 Duo E6750 finished just slightly ahead of the similarly clocked Core 2 Duo E6700 in PCMark05's CPU performance test. The processors higher front side bus frequency doesn't allow it to catch the faster Core 2 Extreme X6800, and the quad-core QX6800 is simply in a league of its own.

"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.
PCMark05's memory performance module does show that the E6750's 1333MHz front side bus frequency gives it a marked advantage over the similarly clocked E6700. Once again the chip wasn't able to catch the X6800, but the higher FSB does result in better memory performance overall.
