Maybe it's separated from the SoC, in its own die? It would make sense. All handheld consoles usually come with a specific architecture that differentiate them from similar mobile platforms and bump the performance.

Doesn't seem like its on its own die ...

The Fujistu part is the FCRAM (main RAM of about 128MB I think). 

Here are some graphic demos of the New Shield in motion:

Borderlands prequel, Crysis 3, Doom 3, and an impressive looking Talos Principal.

Keep in mind this is a MOBILE chip running in a $200 consumer kit sold at a hefty profit.

Yeah I think Wii U ports are going to be doable with mobile tech ... who knows maybe even some PS4 downscaled versions might even be possible.

Look at how tiny the chip is as well:

You could easily take tech like this and put three of these into a very small box and get really impressive performance. 

So do u think Nintendo's next devices will use AMD "Skybridge"? I'm no tech expert but from what I understand, it will share both an ARM & x86 architecture on a single motherboard. If that's the case, wouldn't it be really easy for such devices to recieve mobile ports along with console ports assuming that Nintendo's next devices are able to support the popular engines like Unity/Unreal 4? That alone would likely help out alot with 3rd party support on top of the stronger 1st party output Nintendo will have with a unified approach.

Those demos were really impressive!

It would be cool to see a next-gen Codename S.T.E.A.M with Borderlands visuals

I don't think they will use x86 at all. But these demos show that Unreal 4 runs fine on the Tegra X1 with just ARM cores. ARM is super common these days, cheap, power efficient, and Nintendo already uses them, so they just make sense. 

I think if Nintendo goes with a little more power it will be more to get Square-Enix to give them a version of Dragon Quest XI actually. If DQ is going to PS4 they probably want Fusion to be powerful enough that it can also run DQXI (I think the series will go multiplat like Final Fantasy has). 

Beyond that though I don't think Nintendo will put too much thought into what Western devs want (for better or worse). I think their play with Fusion is that they can support it mostly on their own if need be, but they will still want (even need) to dominate in Japan. 

1 TFLOP at half-precision floating points. The X1 GPU clocks 1.2 TFLOPS at single-precision, 32-bit floating points.

The Tegra X1 would indeed be 512 GFLOPS next to the Xbox One GPU, or about 40% as good. With RAM as slow as the Geforce 7 or 8 series.

Sony used shenaningans like these to call the PS3 a 2 TFLOPS console.

On  practice the Tegra consoles will likely perform close to 7th generation consoles. Not 8th.

(A bit like the Wii U)

The memory bandwidth seems to be the big difference, but Nintendo already uses eDRAM on the 3DS, the New 3DS has 10MB of eDRAM, rumored to run at 30-50GB/sec, which is actually fairly fast. 

Maybe a Fusion handheld with 2-3GB of normal low latency RAM + a eDRAM buffer of 24-32MB at 50-100GB/sec bandwidth wouldn't be out of the question. 

Unlike Nvidia's setup, Nintendo likely wouldn't just use a standard mobile RAM setup, so that would be one difference. 

I hope you people here know that Nvidia's asking price won't be low ...
