3DMark05

Since 3DMark05 is a bit older than the previous test, it is reasonable to believe that the test is quite CPU limited in comparison. Because of this, we should notice some more substantial results when testing the processor at different clock speeds.



Obviously we did not run nearly as many tests for 3DMark05 as we did for 06. This is because the results we were looking for were yielded straight away in the testing process. After a pretty sizable 20% overclock (533MHz) of the E6700, the score increase we achieved was pretty dismal. Also, because we were curious, we overclocked the video card by 50MHz on both the core and memory and achieved similar score increases in the process. This information led us to believe that either the processor does not scale well, or neither of the 3DMark tests could provide us with very good results. The answer becomes clear later on in the Overclocking section, where we ran a few more extensive tests.

PCMark05 – CPU Test Suite

We chose to run the PCMark05 CPU Test Suite because after evaluating it, we felt that it put the processor through the ringer in terms of stressing out the system and variation of tests. The CPU Suite includes tests for File Compression, File Decompression, File Encryption, File Decryption, Image Decompression, Audio Compression, and two pretty intense Multithreaded Tests that simultaneously run several of the aforementioned tasks. Again, here are the test results in the same format as before. (Note: Keep in mind that each test was run three times and that our overclocking experience and results are examined later in the review.)



At last we have found some solid evidence of scalability with clock speed. You can see that the scores for our E6700 increased a full 2000 points with a 30% (800MHz) overclock. Similar results were achieved with the X6800 after a 20% overclock. Note the score of the AMD FX-62 that we obtained from a public file. Even the E6700 at stock speeds beats out the FX-62 by a good margin according to PCMark05. To put these numbers into further perspective, the E6700 at 3445MHz thoroughly trounces the Pentium D 955 Extreme Edition overclocked to 5107MHz in multimedia tests, especially physics and 3D processing.
