Nintendo Switch 2GB or 4GB?

About the GPU stuff:
-Little Pascal doesn't have that much efficiency improvements over Maxwell, besides VR related stuff. I don't think that there's a big difference between both if manufactured in 16nm.
-Tegra Drive PX2 only has more GFLOP/s because of more clock.
-Foxconn leak talks about a GPU clock of 921MHz. With 256 shaderunits that's 460 FP32 GFLOP/s.

Now the important part:
You can't compare GFLOP/s from different GPU architectures. Maxwell and Pascal are way more efficient per GFLOP than the GPU's Xbone and PS4 are based on. And lightyears ahead of the VLIW5 shaders the Wii U GPU was based on.
It's not so farfetched that 460GFLOP's for Switch would equal half the Xbone power. And it would be a big leap over Wii U's 176 or 352 GFLOP/s, depending on how many shaderunits you think it has.
And even if the Eurogamer stuff is true Switches GPU would be way faster with 384GFLOP/s.

So yes, there's a use for more RAM.

So, RAM:
-It's quite ceap. Well, if you use standard stuff as Nintendo did. Now, 1600MHz leaves as with 12.8, 19.2 or 25.6GB/s depending on the memory interface.
-That memory interface means you'll need a certain amount of chips.
-Clock, bandwidth and memory interface tell us it's not 3GB. Tegra is a bit memory hungry and 4GB aren't much more expensive than 2GB.

Basically, Switch can make use of 4GB RAM and yes, the GPU is way more capable than Wii U's GPU, at least docked.
But i can tell you that even in tablet mode Zelda and Mario Kart run better than on Wii U.
