Mark,
It pertain to all PP Suite Products.
Keep in mind that the performances will vary a lot based on the project you are developping. For example, if you have a simple data file, with no images and it's just a letter on plain white paper, this is going to work fine even if you have a system that is a bit below the requirements.
If, on the other hand, you use a complex Workflow process with huge data files and lots of forms that contains large images and complex presstalk code, even if you have above the requirements, it may still take a lot of time to process.
So the requirements, while a useful reference, should be taken with a grain of salt. It depends a lot on the workflow you intend to build.
Hope that helps!
Regards,
Rapha
