Thats what this rumor says if its true.

Close to PS4pro level performance of the GPU.

Imagine if it has a better cpu? more memory bandwidth (it has a 384bit bus).

This could be very close to PS4pro.

And with the way Nintendo makes games, you can basically be sure if this rumor is true it means all nintendo games 4k.

Im hesitant to believe it, it sounds too good to be true. And its very differnt than all those rumors of a hybrid console, tablet.

There's nothing actually saying it's the AMD 7xxx series though. That said, I don't expect 3.5 flops. If we're believing Ruby - and I do - the system will run at about 2.5 flops. I believe Nintendo targeted easy PS4 ports with NX, and as such I believe similar architecture to the PlayStation, with slightly more power.

[...]  

Like I wrote, SMD had real source but he losted it very fast, after that he is talking nonsense most of time, he was talking that NX is Polaris based and that will be stronger than PS4, even competing with PS4 Pro, lol.

Really  believe that  rumor? The rx460 is about 2.5 tf and is 14 nm with a much lower power draw and cost.  If its "older tech" as their tweet indicated, its hard to imagine 28nm, too expensive and power hungry. 

Do you have a link confirming this?  I know that SMD went silent for a while after that leak, but nowhere have I seen that he lost his source or is no longer privy to their info.

Well his "source" got fired from Nintendo. That's a pretty good way to lose your info, beyond that though I doubt NOA regular joe staffers really know anything more about the NX than any of us do. 

NCL treats NOA like shit, and only gives info on a need to know basis and the people who get that info on a need to know basis aren't dumb enough to leak it, because you don't get that high up in Nintendo being loose with information in the first place. 

Beyond that SMD has never claimed to have a source for his AMD claims, he's basically just saying what he wants in the system and betting the farm that one of AMD's semi-custom wins must be for the NX. Which is unlikely to actually happen, because Nintendo doesn't give two farts about what people like SuperMetalDave think or want. You'll get Mario and Zelda and you will shut up and like it is basically what it is. 

Why do you have a problem with the memory bus?

*Edit* I've taken a look and that description could also refer to the Tonga GPU of the 380X. It also has 2048 shaders and, while the retail version is limited to a 256-bit memory bus, the actual chip is 384-bit capable (source: PcPer). It's just that AMD decided not to use it.

How does this stack to the base Xbox One?

this rumor is 901 Gflops (FP64)

vs

Xbox One Slim 1400 Gflops (FP64)  / PS4 1840 Gflops (FP64).

So its not that far off, also with that 384bit bus it ll probably have more memory bandwidth than the PS4 or XB1.

There's nothing actually saying it's the AMD 7xxx series though. That said, I don't expect 3.5 flops. If we're believing Ruby - and I do - the system will run at about 2.5 flops. I believe Nintendo targeted easy PS4 ports with NX, and as such I believe similar architecture to the PlayStation, with slightly more power.

Way to many PCB layers and memory chips to pull off. It would drive prices way to high.

It could be Tonga... But then it doesn't remain in-line with the tweet that said the device was using older tech.
However, AMD's GCN is pretty modular, it would be easy to update a few aspects of the chip.

Roughly 5x the GPU capability, accounting for efficiency gains, in my opinion.

... Those flop numbers are all out of whack and wrong.

If we were to believe Ruby, then you would be wrong. It's not 2.5 Teraflops of single precision.

To calculate flops it is Clock Rate * 2 * Shaders.
Ruby stated the Clock is: 880mhz * 2 * 2048 shaders which is about 3.6 Teraflops. (For all that it's worth.)

So which is it, you either Believe Ruby or you don't? :P
