Nintendo confirmed that Miiverse and internet browsing will not work with Smash Bros on 3DS, but WILL on N3DS due to memory constraints. While this doesn't confirm the amount of RAM, it does confirm that N3DS will have more which corraborates with the information we have so far.
While working through the latest 3DS firmware updates, some coders were able to find some information possibly relating to the New 3DS.
The regular 3DS has 128MB of standard RAM and 6MB of dedicated VRAM so this would be a rather large boost to the hardware besides the confirmed CPU boost (which is also likely 50-100% boost by examining current 3DS clock rates).
Based on disassembly of certain sysmodules for code added/changed with in the 8.0.0-18 update, it appears that the "New 3DS" has the following changes:
- They extended FCRAM from 128MB to 256MB.
- They added another VRAM (?) of 4MB.
Going by the 8.0.0-18 update, which added support for the mem-regions listed above, it appears that the "New 3DS" will use the exact same system-titles as the original hardware(with a new system update at launch, for old/new hw, as both seem to use the same system-titles).
Since this is dug out of the latest firmware version but is not specifically labeled 'new 3ds' there is a small possibility that this is for something else, but the timing strongly indicates it.
(edit) Second rumor via Nintendomination, the source seems a lot muddier (unnamed 'developer') and it's displayed in a rather crummy way, so take this with a bit more grain of salt than the original information which was taken from the 3DS firmware itself.
I suppose this is a better thread for this.
Rumoured specs according to NintenDomination's Tilman
For those who can't see the video
New n3DS Codename = SNAKE
3x more CPU Clockspeed
RAM Speed Doubled
GPU and VRAM are the same
There's a bit of contrast compared to what stated by the OP, isn't it? Fake/bogus/Tilman's creations...what do you think?
EDIT: To be honest, I think I could give more credit to the 3DSbrew guys, currently. XD
