I really don't expect that we will see a PPC 7500 equiped PowerMac. The PPC 7500 does, supposedly, correspond to the BookE spec but it is designed to be an embedded processor not a general purpose CPU. Motorola is supplying them to Cisco for their routers.
The performance of the 7500 ISNT all that great. It doesn't appear to be any faster than a G4. It does, however, have on board memory controllers, on board dual channel GigEthernet... It is pretty much a system on a chip. This isn't what we need for a professional desktop machine.
If there is a 'G5' in development (I believe there is), I would expect that it would be a new processor and I would expect to see better than G4 integer and FP performance. At least I'd hope to see...
As for the analysis of the numbering scheme... remember that the numbering only holds true for the G4 line of processors.
G4: 7400, 7410, 7440, 7450...
The previous GENERATION of processor was 7x0. The G3 comes in PPC 750, PPC 740... designations.
if Motorola and/or IBM stick to naming conventions... we will something different for a real G5 processor. Perhaps a PPC 8500 or a PPC 75000. Either could be conceiveable based on past generational numbering.
I believe that the 7500 is just an extension of the 74x0 processors. I believe it has less architectural changes than many think, and I believe that it is target for the embedded market only (as Motorola has themselves said).
....stupid ffakr.
