Around the introduction of Alpha, DEC punted on VUPS.

VUPS wasn't particularly representative across VAX. With Alpha, less so.

There was a while where SPEC was occasionally used, and IIRC 
occasionally even some TPC benchmarks for database-related, but tended 
to misrepresent system performance.

This was all part of the genesis of the DEC customer benchmarking and 
test lab at DEC ZKO Nashua; test the actual customer apps on the actual 
servers.

For those that do want pictures, some performance charts:

And then there's this:
Raspberry Pi 2 at 1 GHz offers 4,744 Dhrystone MIPS, as compared with a 
VAX-11/780 offering a single, solitary MIP.
