PCMark05 is a more straightforward synthetic benchmark than many of our other benchmarks but we continue to use this for its ease and simplicity that end-users can use for simple reference testing purposes. As such the results in PCMark05 are quite skewed towards higher clock speeds and the likes where the Core 2 Duo E6300 system overclocked to 3.36GHz and its faster operating DDR2-1000 memory gave the system slightly better scores than the overclocked E6420 system. Still, it is plenty faster than all of the stock clocked dual-core systems as shown below.

The outcome from Cinebench 2003's highly-threaded rendering benchmark came as no surprise to us as we've witnessed time and time again that it thrives on clock speeds improvements than other 'feature' enhancements like added L2 cache. Thus the 3.36GHz Core 2 Duo E6300 had a slight advantage here.

However, as our XMpeg encoding test shows, clock speed advantage isn't everything. The results indicate that the Core 2 Duo E6420 at 3.23GHz managed a small lead against the overlocked E6300 at 3.36GHz and shows off its L2 cache prominence in this test.
