XBox 2 Dev Kits

My point was that in 32 bit the Power processors will probably continue to have a slightly different/expanded instruction set.
 
So then you'd also have no problem with saying that the PS2 is just an SGI in a black box and the GCN is completely original design as well then would you?

Nah, that would be the N64.... ;) ;)
 
The difference is that the former is absolutely fictional and the latter is absolutely true...but it isn't surprising that there would be people who need this pointed out (again and again and again and again...).
 
Don't you think it's strange that you're seriously ascribing a human characterization to an entire company... selectively even?
 
You really must have a hell of a lot of time on your hands Quincy :LOL: Look you can rant and rave and make things up all day long. But its not going to draw me into one of your repetitive cut and paste fests. So you might as well just give it up.

The simple fact is your initial comment was nonesense, because what tkf said simply does not describe GC. I've shown you why that's true numerous times, so if you can't understand it by now showing you again isn't going to do much good.

Well what the heck *is* a Mac CPU? I mean there's been 4 different cores released on Macs since 2000, and of those 4 cores there's been about 10 revisions.

I didn't say it wasn't a Mac CPU. What I was saying is that altivec wasn't Gekko's only modification over the Mac CPU it was derived from AFAIK.

So then you'd also have no problem with saying that the PS2 is just an SGI in a black box and the GCN is completely original design as well then would you?

Exactly.. :)
 
The Xenon dev kits out right now are not actual Xenon hardware. Remember the first X-Box dev kits were just PCs with a Geforce card, and the first PS2 dev kits were software emulators. You can't draw conclusions based on alpha dev kits, it does not really reflect on what the final hadware will be.

Of what use are these kits then? Pre-production & planning?
 
I imagine they let developers start working with the software and allow them to start ironing out their content production pipeline.
 
Not sure if this has been posted yet, but still:

Reports suggest that Xbox Next's hardware will not be unveiled at the forthcoming Game Developers' Conference.

Microsoft's chief Xbox officer, Robbie Bach, will take to the stage at the GDC on 24 March to discuss the new console - but may limit himself to games and some technical aspects of its format.

Report also mentioned this on the CPU's (again, I know there has been plenty of XB2 CPU discussion here, but I don't know if this has been said quite as definitively):

It's already known that Xbox Next will feature six next-generation IBM PowerPC processing cores, spread across three discrete CPUs, and an advanced graphics hardware solution provided by chipset manufacturer ATI.
 
Yeah, there's another thread about that. ^_^ Annoying, but somewhat typical. No one wants to be the first to pop ALL the way out of the box...

Obviously not as much time as you dude. Why are you posting this now? I could care less what you think, let alone how you blew my comment completly out of proportion.

The simple fact is your initial comment was nonesense, because what tkf said simply does not describe GC. I've shown you why that's true numerous times, so if you can't understand it by now showing you again isn't going to do much good.

Quit fooling yourself. My comment makes as much sense as the description of xbox. Gamecube development also started out on a MAC, so what? I asked this before, what difference does it make how someone refers to the system? Xbox is a PC, gamecube is a mac, and PS2 is a SGI in a box?? why do you care? that's teh real question. I explained my reasoning for my thinking and you just ignore it anyway, so why bother drumming this up again?

look, if you're going to try and pick apart a one sentance post I made, then you obviously feel the need to argue, so quit bitching about a "cut and paste fest " when it's just what you set out to do.
 
Dave,

I think they are all supposed to be true multithreaded CPU's or something along those lines possibly...

I believe that the CPU of Xbox Next is a variant of the POWER5 processor , but there are 3 dual core chips [instead of 4 dual core chips, as in the server version of the processor ( http://www.beyond3d.com/forum/viewtopic.php?t=10182 )]....

I doubt that since there haven't been any 32-bit POWER processors made in years... As for 32-bit PowerPC processors, well as far as the PowerPC ISA is concerned, 32-bit only implementations will always contain a subset of the ISA. Obviously some will have extensions and modifications outside the ISA for application specific purposes (e.g. AltiVec/VMX/Velocity Engine)... Of course you can same of the 64-bit brethren as well...

Nah, that would be the N64....

Well I was trying to stay current... ;) After all I could've gone on about Saturns being like rice-cookers or vacuum cleaners with remotes, or the MegaDrive/Genesis being a Mac or Amiga without a floppy drive...

Gamecube development also started out on a MAC, so what?

Really? I wasn't aware you could even develop a title on a Media Access Controller... :p

Power 4 and 5 are both PowerPC processors because they implement the PowerPC instruction set architecture (ISA).

They just differs from Motorolas (G4s) in that also implement the 64 bit extensions, whereas the G4 only implements the 32bit subset.
