I thought so as well. Here are the results:

#######################################################

System being used:
HPCPUNAME = SERIES 939-020
Rated CPU speed: 120 MHz

Measuring speed...
user MHz =   80; hardware MHz = 119.3

Note: appears to be a reduced clock-rate CPU

Determining max burp size...

Max burp size about = 482 microsecs (56415 ticks)
user MHz =  116; hardware MHz = 116.1 (#i =    56376)

The full rate CPU appears to be    1.4 times faster.

########### SAME exact system with model string changed #############

System being used:
HPCPUNAME = SERIES 969-120
Rated CPU speed: 120 MHz

Measuring speed...
user MHz =   80; hardware MHz = 119.5

Note: appears to be a reduced clock-rate CPU

Determining max burp size...

Max burp size about = 482 microsecs (56415 ticks)
user MHz =  116; hardware MHz = 116.1 (#i =    56376)

The full rate CPU appears to be    1.4 times faster.

##### A real 969-120 ########################################

System being used:
HPCPUNAME = SERIES 969-120
Rated CPU speed: 120 MHz

Measuring speed...
user MHz =  119; hardware MHz = 119.4
######################################################

System being used:
HPCPUNAME = SERIES 939
Rated CPU speed: 100 MHz

Measuring speed...
user MHz =   77; hardware MHz =  99.0

Note: appears to be a reduced clock-rate CPU

###########################################################

System being used:
HPCPUNAME = SERIES 979-300
Rated CPU speed: 180 MHz

Measuring speed...
user MHz =  191; hardware MHz = 179.6

############################################################

System being used:
HPCPUNAME = SERIES 989-250
Rated CPU speed: 240 MHz

Measuring speed...
user MHz =  255; hardware MHz = 111.4

############################################################

System being used:
HPCPUNAME = SERIES e3000/N4000-100-22
Rated CPU speed: 440 MHz

Measuring speed...
user MHz =  237; hardware MHz = 438.3

Note: appears to be a reduced clock-rate CPU

Determining max burp size...

Max burp size about = 384 microsecs (167074 ticks)
user MHz =  464; hardware MHz = 435.1 (#i =   178178)

Note: some CPUs are very good at executing more than one instruction
      per clock cycle ... on such systems, the 'user' MHz may
      sometimes be more than the actual hardware MHz.

The full rate CPU appears to be    1.9 times faster.
