Maybe not so puzzling. From the February 1989 and April 1989 issues of MIPS, 
in round numbers:

                      Dhrystones     Whetstones-single     Whetstones-double
VAXstation 3100         4000             3000                   2000
Dell 310-20+80387       4700-4900        1600                   1400

Further details available from the issues cited above.
