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).

no matter what they will call their gpu it will still bei a radeon hd 7850 oc


By this logic all ATI graphics cards in last 15 years are Rage 128 Pro but with lower manufacturing processes.

well the the whole 7000 - 9200 series pretty much was the same chipset.

They will a design based on a existing design. This happens every console refresh. Nothing is new.

7000 - 7500 and 8500 - 9200 were quite different; the former were fixed-function DX7 chips, the latter somewhat programmable DX8.1

I don't follow that analogy; GPUs have experienced dramatic changes at the architectural and design/organization levels in the past two decades. So it is not a matter of just fab process advances.

I think the previous poster was referring to the fact that the GPU architecture of the PS4 is a known quantity. As such it should be relatively easy to speculate, at the very least, some performance expectations, by simply taking into account parameters such as the expected fab process, expected bandwidth, clock frequencies, etc.
