For all of you using some random X multiplier, please stop. You are just proving how little you know what you are talking about.

And for those saying X Console will have Y GPU, please stop. You are just proving how little you know what you are talking about.

That the Nextbox is based on the Radeon 7000-series is a fact (mainly. Most likely it's custom built and has some features from future 8000-series architecture). According to Charlie it's 99.9% certain:

And if it follows the pattern of Xbox 360 visavi the Radeon 1900 it has good potential to be 10 times faster than the X360 based on the fact that the Radeon 7970 is 10 times faster than the X1900.

Sorry but not fact.   Charlie is hit and miss and on this one, he's a miss.  The only thing he's actually 99.9% sure about and correct is it will not be an x86 CPU but that was never a hard thing to figure out to begin with.

As for GPU, all he says is Southern Islands/ HD 7xxx series.  Assuming he means the HD 7970 is laughable.  At best, an HD 7790 with the bit depth in half and reduced clocks.

You can't just arbitrarily say the next X will have whatever GPU is rated at 10 times the FLOPs count of the X360.  Far too many factors involved beyond just FLOPs to consider.  Heat dissipatoin, energy consumption, die size, noise, system bus to RAM depth, cost and more.  And the X360 GPU (Xenos) is more akin to the X1800 XL than the X1900 (though with R600 series unified shaders).

I didn't say the Nextbox GPU would literally be based on the 7970 but it will be based on the 7000-series architecture. I use the 7970 as a reference as it's the strongest GPU in the series just like the X1900 was the strongest of the R500 architecture. Also it's easier to communicate by using a specific card that people know the specs of (like the GTX 580s running the Samarithan demo).

The Nextbox will not be as strong as the 7970 because that would mean it's 15. But just like the X360 GPU is around 0.7 x the Radeon X1900, the Nextbox GPU could be 0.7 x the 7970 and the end result is that the Nextbox is 10 times faster than the X360.

Btw, I do not compare consoles or GPUs by comparing FLOPs numbers, I use other parameters.
