That's totally wrong given a 68030. I'm not sure why? Maybe you found a bug or "assumption" in SysInfo?
There are plenty. Here is what it thinks a 68060 is in an A1200T.

Hi,
Show off!!!
This is what a 68060 looks like!!!
Yes a 68030 running at 24 mhz usually looks like that, you will see some increase in some games, but that is all. You can try some more ram, it might help especially for caching.
