This silly myth about the prowess of the Cell BE was mostly nonsense 6 years ago, and is outright ludicrous now.
What are you talking about? Crossfire does not imply high power consumption, especially hybrid crossfire with an APU and a lower-midrange GPU.
I think your prediction is absurd. Overly powerful GPU with vastly higher power consumption than a hybrid crossfire solution, and a PowerPC based custom chip that would offer zero advantages at a considerably higher cost? No, I do not think so.
No it doesn't.
Really? I think you don't know what you are talking about.
1. 7850 uses less then 250 watts under load. GPU's in consoles are always modified designs (I.e. a 7850 exactly is obviously not what any console will use, what I am referring to is it's power level) and by the time these consoles release 22nm will be avaible reducing power consumption on a chip of this size dramatically.
2. Launch Xbox 360 consumed a little under 250 watts under load.
3. No console has ever launched at a lower power consumption level then it's precurser
4. It's pretty much a given Microsoft is using power pc they did last time around, Wii U is already confirmed to use it and even Cell is basically a power pc chip as well. It has a long history in consoles and right now PS4 is the only console rumored to use anything else. In fact if anything is for sure it's that Power PC will be used in Wii U and most likely in the 720.
5. 7850 level performance in Christmas 2013 when they launch will be easily cheap enough to stuff into a box that will cost 400 dollars. In fact it's almost cheap enough right now.
Putting all this together and putting recent rumors together it's logical that the 720 will feature a GPU that is most similar in design to the 78** series and will likely continue their relationship with IBM. By the time Christmas 2013 comes around it's easily conceivable all this hardware fits into the 250 watt envelope and going off past history power consumption may even increase a little bit. Epic, Dice and Crytek have all hinted several times over the past few months that both the PS4 and 720 feature powerful hardware and that all three developers want them to feature powerful hardware. There's a story on Gi.biz right now with developers stating model costs have doubled working on next-gen consoles.
I would buy this rumor if it said they were using Trinity and going purely for a system on a chip type machine since this has been rumored before but adding a discrete card into the mix in that type of box simply doesn't make sense. Why would they use Llano when Trinity will outperform it in everyway, still be cheap and will be outdated by the time the consoles come around? Again the rumor makes no sense.
Don't believe me though, read up on beyond3d forums and see what actual developers are predicting for next-gen tech. It's in line with exactly what I am saying.
I mean if you really buy that Microsoft or Sony is going to put two memory pools into the console for each GPU when space is already at such a premium I don't even know what to say to you. The rumor is dumb even if my predictions are off.
Another thing, a 7750 is 50% faster then the chip rumored in this article and uses 75% less power. Is this all starting to come together for you? If this chip was the best perf/watt out there I'd be willing to consider it but it's not even close to that. Again makes no sense.Edited by jtom320 - 4/4/12 at 4:46pm
