<strong>I've just take a couple of minutes on motorola website about PowerPC ISA.
Looking at the roadmap you can see G5 is 85xx rapidIO, extensible architecture...
There are 2 85xx processors :
8540 (one year old)
8560 (PowerQUICC III not for us)
First intersting point the MIPS are the same with the 7455 : 2315@1GHz (8540) vs 2310@1GHz (7455)
The 8540 is based on Book E, has RapidIO DDR memory controller @ 333MHz, it's .13 CMOS no SOI, SIMD,... All the technologies are ther
Will new mac with the 8540 (or a derivative of it) and new MB be faster than the 7455 G4 PM ?
So, does this 8540 processor sound like the "G5" we will in the next weeks ?

There will not be any 8450 chips in a mac, as you stated a DDR memory controlled 7455 will be faster at equal mhz than a 8450. The G5 is strictly an embedded chips, not suited for desktop computers. The G4 was already an embedded chips, but at his time worthing to be included in a powermac.
The future of Mac is the new chip from IBM, precisions will be revealed in october during the microprocessor forum.
