We won't be able to make a reasonable judgement on Switch until we see how games perform and high res images of the chip so we can see how many cpu's, gpu's, memory etc. Even with a high res image there may be additional small pockets of processing power among the i/o circuitry and cache etc. One normal big clue is the memory chips fitted. They are normally stamped with their exact model number which gives away memory bandwidth straight away which is also a good indicator of how much performance a console has. Yes cache can better optimise it but you don't put slow memory and medium or high performance gpu's together you match components by their performance level and this should be a good indicator when a Switch is stripped down.
The development kit had shared slow DDR3 memory and it wouldn't surprise me if this makes it to the Switch retail hardware as the cheapest option for Nintendo but again we shall find out in a few months.
I'm still believing 3x wii u docked and perhaps a 50% boost over wii u when portable based on all the information so far.
The fact the new Zelda game will look so similar across both wii u and Switch makes me feel this is likely. 720p Zelda on wii u and Switch when portable and 1080p Zelda docked.
