That's pretty much sure. Consoles usually go this route because they know bandwidth is important. I hope Nintendo has learned something about that with the Wii U so they ramp up this spec in their next console. |
What would be the max type of bandwidth they could get out of a mobile RAM setup? LPDDR4 lets say? Can you have something like eDRAM on a mobile chip?

I think right now they are at the max with X1. Any low voltage variant of DDRx will impact your performance, since you are aiming for power comsumption instead of raw power. LPDDR4 is what they are using in the SHIELD.
I see EDRAM on a mobile chip as feasible, but with a big catch. The issue is die size. Mobile SoCs are small and have way more embeded components than common APUs on desktops/laptops/consoles. EDRAM uses a lot of space (the X1 APU is huge) so build a mobile SoC in a small die with a considerable amount of EDRAM is probably out of reach.
We will have tridimensional memories in some time, that can change somethings, maybe.
Who was it that was working on the stacked memory? Was it AMD?

There are several companies working on this but it rumors say that AMD already made more pogress than Nvidia and the other companies.

U seem to have a much better understanding of tech specs than I do so in ur opinion what can we expect out of Nintendo's next handheld assuming it has a late 2016 or early 2017 release window and launches at or around $200?
While not on par in terms of actual power, 3DS/New 3DS are able to handle Wii level visuals and ports due to more modern hardware, can we expect the next handheld to do the same with Wii U?
For instance, would games such as Tropical Freeze or Splatoon realistically be able to be down ported to it without too much trouble or would Mario Kart 9 look similar to Mario Kart 8 on a small screen and lower resolution?

25,6GB/s at best scenario. so no, it is in par with ps360 main memory , but xbox360 edram outperform it. Yes, tegra x1 memory is faster than wii u main memory.. but not even close to wii u's 32MB eSRAM pool, which is pretty big amount compared to x360 memory or even xbox one sram if you consider that wii u is designed to render in 720p and xone in 900/1080p.

How is the Tegra X1 apparently able to run games like Crysis 3 in this case though? What's the bandwidth on the PS3 RAM?
The only thing about Nintendo that's making me wanna relate to this is the emulators that'll be released.
simple, it's gimped down version of crysis 3. cryengine, unreal 4 engine are scalable.
PS3 Cell XDR bandwidth: 16.8 GBps – 24.9GBps (in practice)
PS3 RSX GDDR3 bandwidth: 10.6 GBps – 15.5 GBps (in practice)
wii u and xbox360 memory are unified.
this is article about what can you do with little amount of fast edram/esram memory using dx12 or other modern API.
