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).

The main differences between GDDR and DDR are regarding voltages and burts capabilities, but for the most part they end up implementing the same memory technology.

And yes, GDDR5 is somewhat faster than DDR3. I, however, would not refer to a 50% improvement as "many many many times over," perhaps "half a time over"... ;-)


The point here is that although the DDR5 may finally help the GPU in the APU get the data at the rates it needs, that bus still has to keep 8 x86 cores fed on top of that. It is a definitive improvement over the current APUs which are BW starved under DDR3, but it is not going to offer superior performance to off the shelf PCs.
