May I please correct you... the PS4 doesn't have 8GB of GDDR5 RAM... the GDDR5 is on the graphics card... and it's likely around 1GB like most graphics cards are... or maybe 2GB of it maximum.
The number 8 is actually talking about the amount of RAM... which would be DDR3 as DDR5 RAM hasn't been released yet.
