Games Late last night, Sony unveiled the PlayStation 4 - sort of. It's got a custom 8-core AMD x86-64 processor, 8GB of GDDR5 RAM, and a custom Radeon-based graphics chip. It's also got additional chips to offload specific tasks like video (de)compression (livestreaming is built-in!), and there's a large focus on streaming games, but most of it is "an ultimate goal" instead of a definitive feature. It won't play PS3 discs (but will eventually stream many PS3 games), and, while there's some weaselwording involved, second hand games are safe. The biggest surprise? The console itself wasn't shown because it's not done yet. No joke. No price, no release date (other than somewhere before the holidays).

GDDR5 is rated per chip, while DDR3 is rated per DIMM that has many chips.

DDR3 maxes out at quad-chanel(high end CPU 256bit),
GDDR goes to octa "chanel"(high end GPU's at 512bit).

DDR3 maxes out at 3GHz interface frequency,
GDDR5 goes to 6GHz.

So let's recap:
DDR3 = 3bln * 1sec * 256bit = 768Gbps = 96GBps
GDDR5 = 6bln * 1sec * 512bit = 3072Gbps = 384GBps
GDDR5 = 6bln * 1sec * 256bit = 1536Gbps = 192GBps


But yes, you got me there, I was referring to the common PC3-17000 when I said 17Gbps.
