If so, I've been known to make a wager now and then.
Just to define the proposed terms:
I am using the model number of the PPC fabbed by Motorola.
anything else=null and void.
I'm not about to take a flyer on Apple's marketing folks (they may choose to call a G4 generation chip a G5, even if it's not).
Let me know if you really wanna take this bet.
For the rest of you; show me one non-rumor site source that says the G5 is anywhere NEAR ready.
Because I'm using The Register, Motorola, the Microprocessor Forum, and other reputable sources to assert my claim that Apollo is coming.
I'll take that bet, and I agree with your adding the no repackaged G4 called a G5. But just to not be specific (you list the 8500) why don't we just say a 8xxx series chip.
The more and more I look at the 8540 the more convinced a G5 this year is guaranteed. It does have a SIMD unit, though they don't refer to it as Altivec and the SIMD unit has 222 new instrunctions (where did I hear rumors about AltiveII?), three 128b data busses.
The MPC 8XXX series is listed as "Integrated Host Processors" which is surprisingly similar to the 7XXX, 7XX, & 6XX which are listed as "Host Processors". The 82XX and 8XX are listed as "Integrated Communications Processors".
Here's why the G5 will be released (let's also say that and not just announced, so there is no confussion) this year.
1. The 8540 (yes I know it's most likely not able to function as a Mac processor) is a great starting point. It is "Book E" compliant which makes it Mac compliant. It has support for APU's (Auxillary Processor Units) which is what Altivec is. If the SP (Signal Processing) APU on the chip is not already Altivec or Altivec II, it can be swapped for it as stated above (Book E compliant). This could go on forever, just look at all the available info on this chip and the current G4's to see the compatibility and natural progressions. If the 8540 can see the light of day in 2002 a G5 most certainly will. I'd bet the cores are nearly identical.
2. Actually the e500 core will be the core of the G5, here is the exerpt from Motorola's 8540 fact sheet........
Utilizing an SoC platform which balances MIPs, watts, packet performance and cost, Motorola has created a flexible platform architecture enabling multiple products from easily integrated IP. The e500 high performance core implements the enhanced PowerPC "Book E" instruction set architecture and provides unprecedented levels of hardware and software debug support. The e500 will serve as the core for a family of ASSPs for communications, automotive and consumer applications. <hr></blockquote>
Of course I could be wrong about this.....You ask "show me one non-rumor site source that says the G5 is anywhere NEAR ready.
Because I'm using The Register, Motorola, the Microprocessor Forum, and other reputable sources to assert my claim that Apollo is coming."
Well here you go:
[quote] The company also held off adopting G5 PowerPCs made in a 0.13-micron process. Those chips will sport a longer pipeline and hit speeds up to 1.4 GHz, but are not expected to be available in volume from Motorola until midyear. <hr></blockquote>
I just had a thought, the G5 was originally believed to be numbered 75XX as the 8XX & 8XXX (8 series) are considered more embedded chips. So it would be possible that a core such as the e500 could be the "G5" core and used in both 8XXX and 75XX series. This has just become way more complicated than I thought.
I will take the bet, but we can not go by either part numbers or just the fact they call it a G5. We would have to look at the processor and what differientiates it from the G4. Any real architectural differences, not to merely include additional pipelines or larger on-die cache, but true changes that we could look at and agree would make a chip truly a G5 or just a enhanced G4.
What do you say?
