NX Buyers: 1080P Or Better Detail 720P?

They're gonna need some bandwidth for 1080P at home I think.

50GB/sec is quite good for portable mode, but if they want to do the whole "it goes to 1080P with the home dock", they probably could use a 192-bit or 256-bit memory bus.

The 3DS already has a 128-bit bus, which kinda surprised me, so Nintendo going higher would make some sense for NX.

It also probably combined with Nvidia's tiling approach likely means Nintendo won't need eDRAM, which increases cost, heat, takes up a ton of die-space, and creates yield problems.

They won't go for 192-bit or 256-bit. Power Requirements would be far to high.
The higher the bus width, generally the more intricate the memory controller and memory layout and PCB layers become.

The 3DS could get away with it because it's RAM was clocked fairly conservately (200mhz) and it used FCRAM.
I calculated the speed based on the Bandwidth * Bus width rate. I.E. 200Mhz * 128 / 8 = 3.2Gb/s.

To put it in perspective... PC Graphics cards had Bandwidth equivalent to that 20 years ago. :P

eDRAM if used correctly can also reduce power consumption as Intel has shown us.
