The Sun-3 architecture does not specify a clock speed.
The Sun-3/75, 160, and 180 run at 16.67 MHz.
The Sun-3/50 and /52 run at 15 MHz.

The /50 is the cheap machine and people felt that the price
reduction was worth the performance loss.  Given that a /50 is
$7900 while a similar /75 runs $15900 I think they were right.
