Winrar & DIVX encoding
The Winrar applications stresses your system as it handles the bits and bytes to find ways to make the target file smaller and more compact. At normal compression setting the CPU is taxed quite a bit. I used a folder with 296Mb of JPG photo and .WMV movies and timed the total time it took to create the archive.
Next up I used a 67Mb .avi movie featuring Dry Ice and LN2 cooling action to test the speed of movie compression and processing, the AutoGK tools was set to encode the movie with the DIVX5 codec at a 75% compression rate.
The chart below displays the results from both applications, value in seconds, less is better:
I redid the Winrar test several times on the E2160 at stock speeds, the results remained the same, at default speeds the E2160 is ~130% slower than the E6300. L2 cache at lower CPU speeds is vital. Once overclocked to 3Ghz the difference is a lot smaller (~20%).
The DIVX5 encoding test is different, no real sign of a performance impact here, the extra 1Mb L2 cache on E6300 doesn’t make a real difference here.PCMark05
PCMark is not really a daily-used application, but it manages to give quite a good impression of the performance level of you computer.
The overall PCMark05 doesn’t show a big difference between the two processors. The compressions sub-tests even have the E2160 running slightly ahead:
