Here are my Gembench runs, see the pic description for the machine config:

STE 8MHZ (Stock CPU, no booster fitted), 4MB RAM, TOS 2.06, Blitter disabled.

Hopefully this will give some idea of the relative speeds with and without the booster and blitter.

Just for completeness I ran Gembench on my stock STE with 4MB RAM and TOS 2.06, and saved the results. I then ran Gembench with those defaults on my 32mhz boosted STE. RAM and TOS were the same.

Results below, with and without Blitter.

Oddly running the CPU from its own 32MHz oscillator gives integer division a 16% boost in speed
