I have doubts about the claimed huge lead the '60 would have anyway.

There are no doubts.  A 500% speedup is impressive.

There are limits to how far you can push an Amiga, and when you're funneling all that power down through a much slower chipset the losses get pretty significant.
Luckily for him, the CPU does not funnel its power thru the chipset.

It funnels its power from FASTram through its L1 cache and into itself.

Why not just be satisfied that you already have one seriously fast Amiga and leave it at that?
Because his CPU is extremely seriously slow.  A 56Mhz 040 is 3x the speed of a crippled 030 from 1987.  An 060 is even faster than 040.

The 030 tries to run a 56Mhz cpu on 256 bytes of L1 instruction cache.  That is just silly.

I have no doubt an '060 can outperform an '030, but 500%? Pure hyperbole.
What percent would you say then?  479%?  466%?  ???

Time to add 2 IEEE Floating Point Numbers:
68060 = 3 cycles
68030 = around 150 cycles

150/3 = 50x speed = 5000% (That is 5 thousand % not 5 hundred %)

68030 fail
68060 win!

What's it do for the average Amiga software package?
It makes the average Amiga software package run a lot faster.

Sysinfo shows a lowly old-fashioned 68040 getting almost 400% the speed of a 68030.  It doesn't take a genius to figure out that 68060=500%.
