@peemee My 2011 MBP (the first Mac to get Thunderbolt) is the base-spec 2 GHz quad-core i7 with 12 GB RAM & an SSD replacing the original HD. At its release, it out-performed the existing Mac Pro.
This MBP continues to impress: with Geekbench 4 it's out-performing a 2013 21-in iMac that has a 2.7 GHz quad-core i5 with 8 GB of faster RAM & much better graphics.
