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).

Not quite, DDR3 can push over 190 Gbps at the high end (PC3-24000).

So you need a least 176/24*64b = 448bit memory interface with 7 DDR3 modules working in parallel to be on par with PS4. But I'm not sure it will be as effective as GDDR5. Also DDR3 is not a power efficient solution.
