Not really. AFAIK it all amounts to something between 600 to 800Mhz for real world code, at best. About the same for affordable FPGAs.

That aside, I don't really get this nostalgy for these systems. I don't care about Doom, or some port of Quake. While 68K assembly was much nicer for me than anything common today, what do I get from that without a usable Browser, Office, "daily driver" apps? Show me how to port Firefox, Chromium or something functionally equivalent to these, and how those perform! :-)

Or Blender.

(Or Android 68K! (Giggle))

If we're talking about an actual, modern 68060 CPU running at multiple GHz, then it would be trivial to run Firefox or Chromium -- just install Debian m68k and compile. :)

Apart from the nostalgy factor, I suspect there would be no actual benefit from such a system. I doubt m68k would compare well to ARM or x64 in terms of compatibility or modern-app performance.
