Intel Core 2 Duo E6750 Performance And Overclocking
LAME MT and Sony Vegas
In our custom LAME MT MP3 encoding test, we convert a large WAV file to the MP3 format, which is a very popular scenario that many end users work with on a day-to-day basis to provide portability and storage of their digital audio content.
In this test, we created our own 223MB WAV file (a never-ending Grateful Dead jam) and converted it to the MP3 format using the multi-thread capable LAME MT application in single and multi-thread modes. Processing times are recorded below. Once again, shorter times equate to better performance.
The Core 2 Duo E6750 and E6700 finished right on top of each other in our custom LAME MT MP3 encoding benchmark in both the single- and multi-threaded version of the test. Technically, the E6700 finshed the MT test 1 second faster, but since this benchmark doesn't report fractional differences in the encoding time, that actual difference is likely to be less than 1 second, which falls well within the margin of error in this test.
Sony's Vegas DV editing software is heavily multithreaded as it processes and mixes both audio and video streams. This is a new breed of digital video editing software that takes full advantage of current dual and multi-core processor architectures.
The Core 2 Duo E6750's faster bus speed allowed it to finish our Sony Vegas video rendering benchmark about 5 seconds faster then the E6700. Once again though, the faster FSB doesn't give the chip enough of a boost to catch the X6800 and the quad-core QX6800 simply can't be touched.
