actual top speed looks to be 112GB/s on a 128bit bus
"Good enough" for my idea of an elegant solution!
By "Cell deivative" I mean a heterogenous multicore processor suitably rigged for graphics processing. This would be a step down from my ideal of homogenous cores (or at least, homogenous ISA) but better than discrete programming languages needed for separate CPU and GPUs.
Again, I'm just talking a hypothetical elegance here, not a real-world achievement. I'd rather have a powerful GPU and CPU than a mediocre all-in-one solution. I'd also rather have 5 pools of RAM if it meant far better results. But I'd prefer a single RAM pool if there were no trade-offs, and I'd prefer one single core type if there were no compromises with it. Sadly the Real World gets in the way.
32megs of edram would do wonders for the badnwidth issue. couple that with 192bit bus and I think your fine . It will be very expensive to get the bandwidth from edram with another memory pool.
As for a cpu why not something based on Bulldozer. its rumored to be 16 cores and will hit in 2011

or they can use the older Magny-Cours Take the 12 core and move it 32nm and you should get a cool running power full chip that has OOE

Sorry to drop the tech IQ of this thread with this post, but I just got back & had some catching up to do...
You guys might be able to afford to keep your old system & buy a new one when it comes out, but I can't. And I'm not so sure very many console buyers can either. Buying a console for me is investing in a platform. I invested in the original Xbox because it gave me the kind of games & experience I preferred at the time. As the platform grew, I grew with it. Just because the games get replaced with newer versions doesn't mean they stop being good games. So I want to take them with me as the platform grows. It's a lot like the PC in some ways. Yes, you can just keep the hardware, but I can't afford to do that. So I want to be able to trade-in or sell my old system & get a new, bigger & faster system, but still take my games with me. I did that with almost every PC I had before, why is it so hard to fathom that people may want to do that with a console too? IMHO, Sony had the right idea with the PS1 & PS2...
Yes.
You only say that because you're a tech whore. I mean that in the nicest ways of course! But seriously for the folk that reside on this forum I can completely understand why you guys would be against BC: it's a speed bump in the way of the good shit.
PS2 supported this & it was one the coolest things about it. It was definitely something I wanted to see. It would have been great if the 360 had the ability to do this for original Xbox games. Hopefully MS understands that they have a software & services platform(not hardware) that needs to continue uninterrupted instead of starting over from scratch each generation.

You can afford a next gen console early on but you cant afford to keep your old one?
Trading in or selling an old system by the time next gen is here, isn't likely to fetch much.
Anyway, you're already in a situation where Playstation 3 has limited BC depending on model (none for a while now) and 360 as well. So nothing will change if theres not BC in the future, as we dont have it now. You wont be losing anything that you currently have.
It took me over a year after the launch to get my 360 & that was with a bit of help. Yes, selling my original Xbox, accessories & non-compatible titles helped pay for it. If they continue with these over $300 systems for the next round I'll have to wait again. BTW, I didn't get my original Xbox until it was $199 after the first year too.
Tommy McClain
It did for me. Just depends on where you offload it. Sometimes friends, family or even yard sales are better than a store.
Yes, I will. Even more-so now. I now have a big investment in DD titles, that I didn't have before. So when I sell my old system to get the new system, I have now lost all that investment if it's not BC. Explain that to mom & pop, they won't be too happy that's for sure.

Thanks
I read in article from early 2009 that Samsung was using 50nm process for their gddr5 ram. Do these RAM modules still use this process (the ones achieving to aforementioned bandwidth)?
Do some members can make an estimation about how much (or few
) can be gained in this regard by switching production to better processes?That thing will be way too huge and intended for high end server business.
The bright side is that bulldozer is supposed to be scalable architecture. I hope that the core won't inflate tho, Intel now manages to do more than AMD with less transistors.
Well that is the opteron line with most likely larger caches. I don't see why they couldn't do a 12x verison of the desktop chip at 32nm.
Mabye they can just take a bunch of amd neo's (athlon 64s) and put them together. They use about 10-15 watts each at 1.6ghz on 65nm . 8-12 of them would be a killer chip on 32nm and would use less than 80 watts . Or the new mobile phenom 2 quad cores for Danube and put a bunch together though i have no idea what thier TPD is
I dont mind it. MW2 looks good to me and it's subHD. If nobody told me I wouldn't have noticed on my own.
You could probably make a better looking game all around at 600p, then 720P.

People who look for it probably can, i depends how good the scaler is. I agree that for theaverage consumer this is a complete now issue really.
However it does depend, many game on current systems are more like 600 lines scaled up and i think that in that case when you are going down to close to PAL resolution then yes a scaled image is detectable quite easily by most players.
I am interested at howmany people think that AMD might produce some form of anthlon based x86 many cored cpu for the next xbox. To me this seemes unlikely an IBM power based unit along with whatever ATI can produce within their silicon/power budget seems more likely. I imagine this time the cores who be OOO, thing is this way give you BC so easily and and IBM are always very happy to come up with custom designs unlike hisorically the x86 suppliers.
Of course the legal side of X86 is very important. Even if AMD wanted to produce a X86 custom design for MS, MS would want to own the ip for the design, something I am not sure AMD could legally sell them due to huge complications with Intel.
Like someone else said while a 'Fusion' style cpu/gpu die might seem cheap and ellgant and allow huge bandwidth sharing between the chips the yeild trade off would probably kill of this idea stone dead.

Well a 4 core would be around 284mm2 which is a bit too large imho but awesomely powerful with the 16 threads.
If they could come up with a dual core derivate at somewhere north of 160mm2 that would fit and would give you 2 more threads than the Xenon plus a whole lot more.
Offfopic:
Would having VMX units with more registers be that important next gen? VMX256 or something.

I don't the emulating the CPU was the hard part this gen and considering the number of cores one might expect next gen I don't think it will be that hard next gen.
