You were right the first time, it is 10 MHz.

The biggest difference is the WE32100 CPU in the 310 is more powerful than
the older WE32000 in the 3B2/300. Also, the 3B2/300 is no longer sold by AT&T
but the 310 is. Support is the issue I'm driving at. I do believe that AT&T
still supports the 300 but it is an important difference. Another important
difference is the operating systems. The most current releases of UNIX for the
3B line (3.2.X) will not run on the 300 but they will run on the 310. I believe
that the lastest OS release for the 300 will not support SCSI peripherals.
All in all, the 3B2/310 is a superior machine (big surprise eh) above and
beyond the gain in clock speed.
