There are NO differences between the free and the commercial versions in RapidMiner v7.2. The free version comes with all features and functions also offered by the paid version. So if you saw some functionality in some documentation it might have been moved somewhere else, been replaced, or even removed completely from the product. It would be helpful if you could point out where you found this information so we can update this if possible.
But there are two limitatations for the free version:
The first thing is pretty obvious: the more data you analyze the better your models are. The second thing means: the more logical processors you are using, the faster the computation will be done if things are parallelized. For modeling schemes like Decision Trees, Generalized Linear Models, or Gradient Boosted Trees among others, you can see a speed-up of almost the number of logical processors you have (in our example above: almost 4X). In other cases, e.g. for deep learning, we use the extra power to make more computations in the same time. So you won't see a dramatic speedup but will get better models. Future versions of RapidMiner will have even more parallelized methods and will even offer to compute complete processes in the background as well.
Hope this helps,
