The 5770 in the Mac Pro only looks like it has 1GB of VRAM which would make working with larger files worse rather than better in many cases. The GTX 780M in your iMac is excellent in general and has 4GB of VRAM, which is very important for Vectorworks 20 especially. Check the Activity Monitor Memory pane again, if Vectorworks or C4D aren't nearly filling up your available RAM or using anywhere near 32GB each (which I highly doubt they are) then RAM isn't what is limiting you.Ĭomparing the specs of those two machines though, the iMac actually has a much BETTER graphics card.

Well The Mac Pro would definitely RENDER faster in Renderworks as well as C4D (12 cores will probably beat 4 cores at ANY clockspeed and these clocks are close), but I very much doubt your problem handling large files is related to RAM, however there is an easy way to check.
