Macintosh LC III - Interware Booster 50MHz vs Diimo 030 50MHz

[jasa1063]

Last year I picked up an Interware Booster 50MHz accelerator for my Macintosh LC III. I have now gotten a Diimo 030 50MHz accelerator clone designed by max1zzz. I thought it would be interesting to see how well these benchmark against each other. First up the Interware Booster 50MHz. The pictures from left to right are the accelerator front, back, Norton SI 3.5 CPU, Norton SI 3.5 FPU, SpeedOMeter 3.23 and SpeedOMeter 4.02.

Next up the Diimo 030 50MHz. The pictures from left to right are the accelerator front, back, Norton SI 3.5 CPU, Norton SI 3.5 FPU, SpeedOMeter 3.23 and SpeedOMeter 4.02.

The interesting thing is the FPU scores in Norton SI 3.5. The Interware Booster is quite a bit faster. I am not quite sure what would cause this, but I ran it twice to be sure the score was correct.

I suspect the diimo is running the FPU at 25mhz rather than the 50mhz the booster is using. Diimo did the same on the SE30 version for some reason.

Side note, the speedometer FPU scores should be ignored as they're badly contaminated by CPU and memory performance.

Now that you mention it, I did run into the same thing with my Diimo 030 50MHz on my SE/30 as well. That makes sense now.
