This page is intended to give you some background on what happens and how it impacts on performance. Note that the test setup is different than it was in the PPBM5 test. We have extended the time-line duration for better accuracy, we have added XF 4:2:2 PAL 1080i material which puts a heavier load on the disk setup, we have increased the number of tracks to 7 and we have added a number of non-accelerated effects to the time-lines to reduce measurement errors. This makes comparison to old test data from the PPBM5 version impossible.

In addition, we have abolished the use of AME and only use Direct Export, to avoid the huge overhead AME carries.

There are three different export tests in the PPBM6 benchmark.

Let's go through each case and explain what happens in terms of workload, so you understand what may be worthwhile to investigate for further improvement of your system, but keep in mind that when testing acutal sequences with life footage, no single test will ever use just use one single component of interest, be that CPU, memory, disk or video card. It will always be a combination of all of these components working together, and the interaction between memory, CPU, GPU and disk can have non-obvious effects. In one test the emphasis will be one component, in another test the emphasis will be on another component. This is what makes interpreting the results so difficult.
