what speed/bandwidth can we expect the GDDR5 to reach by 2012 on say a 128bits bus?
actual top speed looks to be 112GB/s on a 128bit bus

"Good enough" for my idea of an elegant solution!"Good enough" for what?
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.An x86 CPU + ATI GPU is going to mop the floor with a Cell derivative in terms of end product in almost every case in a 2 year launch window.
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.I don't understand why this is sad--how is a GPU a "weak point"
Magny-Cours will be the first member of the Opteron 6000 series, which will slip into two- and four-socket G34 systems with quad-channel DDR3 memory, up to 12 DIMM slots per socket, and quadruple HyperTransport 3.0 links. AMD plans nine Magny-Cours variants with 8-12 cores and ACP ratings of 105W, 75W, and 55W.
I dont understand why you want BC. Just play it on your xbox/360 if it's that big a deal to you.
I dont agree. I bought new consoles at launch, never cared if I could play my old games on it. If I want to play the old games, I already got the old console so I can always play them besides I dont buy a new console just to play old games. The same goes for new buyers I think. Why buy a xbox next if you want to play x360 games?
Also, do you think that Sony will have full BC with all their previous PSN download titles on PS4 as well? Nintendo on WiiHD/whatever?
If you can do BC for almost free, only then is it worth it. In fact I see a competitive advantage waiting to be exploited if one company burdens itself with BC and the other doesn't (perhaps Sony saw this as well when they dropped BC almost as fast as it came!)
What if the BC improved the performance and graphics of the last gen games? I think that's what the next Xbox will 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.
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.

That thing will be way too huge and intended for high end server business.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

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.
Do you guys really think that on the closed boxes we will see the end of sub-HD games? I've got to tell you that I don't think so.
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.
Can a Power7 derivate fit for an x720?
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.Wont they need to go with a similar CPU as last time if BC is such a supposed big concern?
Dont see why the GPU has to be from ATI for BC supposedly, but they can just switch CPU vendors?
