AMD Kaveri APU Features GDDR5/DDR4? Good read.

This is completely made up. AMD don't have the cash or the reason to do DDR4 in 2013. There won't even be any retail units of it. Intel isn't doing it until 2014 and then only for the very high end.

GDDR5 is even more far-fetched. AMD don't have the market precense to dictate such a switch.

I will bet heavily against either of these things. I'll buy you a Steam game.

AMD Supporting GDDR5 wouldn't be a replacement for DDR3 or DDR4, it's purpose would be purely for Graphics.
However, if we are to go by what AMD has done in the past, the GDDR5 memory will probably be used as Side-port memory, AMD did a similar thing with it's Xpress, Radeon 2000, 3000 and 4000 series of IGP's where it bundled dedicated DDR3/DDR2 memory dedicated to the graphics.

However, they lacked any decent amounts of bandwidth so the performance benefit was minimal at best, the main improvement though came from lower  latency as Physics comes into play. (Closer the memory is to a processor, the lower the latency.)

The other side of the coin though is cost, GDDR5 isn't *Super cheap* yet (Otherwise low-end GPU's would all have it!), Kaveri and AMD's other  APU's are cost sensitive, so they will probably leave it up to the motherboard manufacturers (Which would take on the cost burden) to decide whether they want the GDDR5 or not.

I could be completely wrong though, but it's my take on it. - But we will see once Kaveri launches.
