EPYC CPU Lane Question

I am trying to design a project (for fun) that involves a silly amount of monitors. As we research different technologies that are available to us we found the EPYC CPUs which seemed to be a possible solution because of their 128 lanes. However the wording in a lot of the QAs isn't answering our questions concretely enough.


If we have a single EPYC CPU will we be able to utilize all 128 lanes for GPUS or are there only 64 available to us.


If we have duel EPYC CPU will we still have 128 lanes for GPUS available? We understand that each CPU in this config uses 64 lanes to communicate with each other, but we want to make sure that means we will still have access to the other 64 lanes from both of the CPUS, giving us a total of 128.


Thank you
