Hello
There are rumors about PowerPC 970 2 GHz accellerator boards / cards for old Mac.
Is it possible to create such accellerator for AmigaOne?

IIRC Cyberstorm is actually PowerPC accellerator for Amiga 68K. AmigaOS 4 will run on Cyberstorm.

If such card / module is available, Is it possible to port AmigaOS 4 to 64 bit PowerPC 970 accellerator for AmigaOne?


But what's the point with faster processors, if the CPU has to sit in it's ass and wait for the NB to shovel data through a narrow buses? IMO, there is too much emphasis on MHz and CPU performance, and too little on general system design. Perhaps we have all been so used to the x86 way of thinking, that we are simply stuck in it now?

The new Mac is a breath of fresh air in this sense!
MorphOS is Amiga done right! :)

@ Tigger

Yes I know that it has been put together mainly from standard (but state of the art) "x86 technology". But they have really gone as far as possible in their efforts to remove bottle necks, don't you think? OK, I don't really know, but how common is 2x 1GHz FSB? Memory would perhaps be a bottleneck (would RAMBUS/RIMM perhaps be better?), but "this high-performance frontside bus architecture enables each PowerPC G5 processor to discover and access data in the other processor’s L1 and L2 caches for ultrafast performance" will benefit from this, as well as data shoveling to/from the hypertransport connected I/O, the PCI and PCI-X, AGP, etc. And what about the "Point to Point controller" which shovels data around without even bothering the CPU's and the processor bus? Isn't that even a little "Amiga-like"? Perhaps I am wrong, but I really think this is the most innovative design this far, and I have not seen this on any desktop x86 motherboard, but perhaps I have only missed it? OK, perhaps "innovation" is a too strong word, we are basically talking about removing bottle necks, but at least this focus on removing bottle necks and not *only* pumping up the CPU MHz is a (at least tiny) breath of fresh air?  ;-)

You should add "that I know of, based on publically available information".

Otherwise your statement is just plainly wrong.


:-o

Sawin these seeds of hype! :-)

(well, uh, we have these ... GREAT products coming up, it's secret and you now nothing about it now, but it will ROCK!)

Could it be that there exist an opposing phenomen to FUD?  :-P
