I think a bigger business case is virtual machine hosting, say one of these is maxed out (8 Xeons with 56 cores ie 448 cores and 32tb of memory), say it's divided into a 1000 machines you can run each VM with 40% cpu utilization and 3gb of memory, considering many VM offerings have less RAM (and add a bit of overselling on top of it with regards to CPU) it could probably house over 2000 VM's.
