It’s hard to know how much stock to put into these figures, given that they’re a) on a forum and b) anything but official, but these specs over on NeoGAF at least point to some level of reasoned guesswork.
The poster cites “insider information” from a couple of places, so whilst it’s clearly not concrete (or final) this info should at least prompt some discussion.
The next Xbox, so the post says, consists of a 6-8 core AMD CPU and between 3 and 4 GB of RAM. An AMD GPU rounds off the stats, which together kicks out 1-1.2 teraflops.
The PS4? An AMD CPU with 4 cores, an AMD GPU 1150 SPU, and just 2 GB of RAM, which is “unlikely” to be upgraded. This combo dishes out 1.8 teraflops, apparently.
The truth is that the official details of the next generation of consoles isn’t known by anyone outside the platform holders themselves, but it’s fun to speculate; we’ll see soon enough hopefully.

The PS1 had 2MB Work RAM and 512kB VRAM, the PS2 had 32MB work RAM and 4MB VRAM; almost 16x the PS1 RAM, the PS3 has 512MB total RAM; almost 16x the PS2 RAM.
I think the PS4 will have at least 8x the RAM of the PS3 eg. 4GB and hopefully 8GB of RAM.
