Nope, on my 1.42ghz mac mini even stuff like Aladdin isnt quite perfect (although its pretty close). Having said that though Ive not spend much time fine tuning euae config, so there's probably a little more juice that can be squeezed. From my experiences with it on othr systems, and the difference a bit of tuning can make Id hazzard a guess it could be maybe 10-20% either side of a stock a1200 without fastram (depending on the game).

Big difference between a similarly specced G4 vs. an x86 system with euae (favoring x86 of course). Hopefully this will change eventually, but if the "progress" reported thus far for the ppc jit 68k emulator is anything to go by I wouldnt hold my breath unfortunately.

I thought Aladdin 4D would run on MorphOS without E-UAE?  I have not yet tried to install and run it on my MorphOS systems, but have been planning on trying it soon.

As for which would be the fastest G4 PowerMac to run MorphOS on, I have decided to upgrade my dual 1.25GHz MDD PowerMac to a dual 1.42GHz G4 processor board and possibly overclock it to 1.5GHz or 1.67GHz.  Most, if not all of the third party accelerated G4 processors for the MDD models of PowerMacs do not have any L3 cache.  The performance of the 1.8GHz G4 (which is the fastest you can get for the MDD G4 PowerMacs) is probably slower than the 1.42GHz overclocked to 1.5GHz or 1.67GHz with it's L3 cache, depending on what type of benchmarks you are running.

If you can get a MDD G4 PowerMac with a 1.8GHz accelerated G4 board in it for a decent price, I would say go for it, but if you have to pay a $200 to $350 premium for that accelerated G4 board, I would suggest doing like I am and getting the stock dual 1.42GHz G4 processor board with the 2mb of L3 cache (which I found for only $50) and if you want more speed, overclock it a bit.

There is one or more 2.0GHz G4 accelerators for the Quicksilver G4 PowerMacs, but then you are using a computer with a slower bus and memory, so I doubt it would be much faster than even a stock 1.42GHz G4 MDD PowerMac.

I would like to see a complete list of several different benchmark results for all of the different G4 PowerMac possible combinations and speeds.

I thought MOS doesn't support multithreading? Not a whole lot of point in getting a dual-processor box if that's the case, unless it's simply to make overclocking easier.


GeekBench has a broad variety of user-submitted benchmark results for PPC Macs, don't know if you'll find any results from machines with third-party accelerators, though.

To my knowledge there isn't any Amiga, or Amiga "Like" operating system anywhere that supports multithreading, or multiple processors yet, but many MorphOS users that are running MorphOS on Mac hardware have their computers set up to dual boot, or triple boot into other operating systems that DO take advantage of multiple CPU's.
