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. |
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.
JRPGfan said: 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. |
... Those flop numbers are all out of whack and wrong.
TheLastStarFighter said: 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. |
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
