http://papillon.is.tokushima-u.ac.jp/hardware/ppc460ex/ benchmark from the amcc 460ex eval board running at 800 mhz. There are some "real world" video decoding benchmark for the 440ep board, that can be compared to the 460ex eval board too. http://papillon.is.tokushima-u.ac.jp/hardware/ppc440ep/

Also worth noting from a different site: http://embedded-computing.com/amcc-powerpc-460ex-460gt-processors
Pricing and Availability

AMCCs 460EX and 460GT evaluation kits will be available in May and may be ordered from AMCC or any authorized distributor using part numbers EV-KIT-460EX-01 and EV-KIT-460GT-01. The suggested distributor resale price for each kit is $995. For more information, please contact your local AMCC sales office at http://www.amcc.com/Sales/.

AAND:
The old specs for the 460ex is to 1.2ghz, why this has changed i dont know, but if you look at that .jp site it does say 1.2.

Just for kicks im tracking down the benchmark used:

Really? What are you basing this on?

The numbers I've seen are:

Difference is, MOS isn't trying to be something it isn't (Amiga). I suspect when Hyperion & Co. stop misappropriating the Amiga name they will stop being the target of so much criticism as well.

Dear Jorkany. On behalf of anyone wanting to see the Amiga move forward since 1993, id like to declare your comment as trolling, as the head chief of trolling on the internet has already approved you to the position as troll of the camp, i would hereby like to offer my support for this ruling.

Now to get to the bottom of "misappropriating" which by whereby ye me(n)th, actually means bringing the original Amigaos incarnation to new highs, we, the trolling association of amiga vaporware will have to disregard with this ruling previously reached, and label you only as a freak of computing, or scum of the earth. However, if you wold not like the Original evolution of the OS to succeed press #2. Would you however like, to see, any professional effort on behalf of the platform to bring the OS up to speed, press, #1. If you do not at all appreciate this effort, it being years behind the "competition" press #hangup.   http://www.youtube.com/watch?v=QXx-n6T7tZg

Seriously, if you fail to understand or see that the Amigaos in any incarnation is actually quickly becoming something the vast majority of computer users out there would desire, due to its light weight and good use of hw , ( be it that in this dream mode they would all have to "unite" AND conquer ). Truly, atleast the Morphos camp deserves loads of credit for beating Apple on its own platform, and we see OS4 yeeears behind already preforming good on the same HW. Which only goes to show what the competence left in the scene is able to do with the little resources they have.
