Changes in PS3 hardware are anything but trivial...
#1
MASSIVE changes on GS connectivity, changed "supposed scaler", and 65nm southbridge.
I don't know if the new PS3's will end up with better or worse backwards compatibility than the first models, but what I do know, is that what newer PS3's will be able to do by software, in terms of emulation, older models won't. The GS is now connected both with RSX and the scaler (It is the scaler, isn't it?) with very wide buses, and in the older model, the PS2 hardware is basically isolated from everything else. Have a look. I've arranged the perspective from existing photographs to make them similar. The result is not polished at all, specially on the edges, but it's useful ![]() American PS3 ![]() European PS3 ![]() American PS3 -> European PS3 ![]() |

I think they changed the cooling system in the Euro PS3s as well, but i haven't seen any comparison shots.

I think the 20gig will be introduced around holiday season with the internal modifications and a price drop. |

Just a few infos: the numbers of total components on the board supposedely halved from 4000 to 2000.
Costs associated with Blu Ray are sinking (Blu Ray players will be in the 500-600$ range from 1000$+ in a couple of motnhs). Sony said it expects to sell PS3s at a profit starting from September. |

Looks like they could cut out the left side of that motherboard after they removed the GS/ES chip.

What a shitter to split the userbase like that this early.
I was considering buying a PS3 now to ensure that I'd be getting solid BC, but now this complicates all that. If it turns out that software BC ever comes to have some advantage over the traditional, early adopters am boned. The potentiality of scaler hardware is also huge. |

If this somehow means that late adopters get PSX/PS2 upscaling and early adopters don't, I'm going to be pissed. I just bought a PS3 so I'd have full hardware compatibility, and now you're telling me that I might end up getting the short end of the stick because I won't be able to upscale my PS2 games? ****!!!!

Hmm, if they dropped that many components, then it must be on the back side of the board. It doesn't look like they were able to shrink the board at all, and the only drastic changes are to the left side of the board. I didn't think the GS would be that big by itself @ 90nm. I can only assume additional logic has been put in place to handle communications with Cell. I can't tell if that's running off FlexI/O, though that would make the most sense, since that's the direct connection to the EIB. It looks like the GS is also handling whatever video output functions Cell used to handle before. They also moved that pair of chips from the middle of the board over to the right side of the smaller SCC(?). Did we ever confirm that it's the SCC besides the die comparisons? Anyway, I wish we had another flowchart of the new board. PEACE.

If this poster agrees with you, you're doing something very wrong.

From the games I've tried emulating on my PAL PS3, I'd gladly swap that for the hardware version in the US/JPN models. The emulation is rubbish!! I've tried plenty of games and there isn't a single one yet that I'd say I was happy with...everything has been a slow, jerky, horrible, mess - and that includes games that got a 3-point rating on Sony's website (ie games that were meant to run almost perfectly)

One requirement is that TVs should support and be able to scale between 720p and 1080i. It really shouldn't make a major difference what they do with their scaler. In fact I wonder why they're even bothering with it given the single whacky scaling mode it allegedly supports. Perhaps it does some other things too. |

Wait, so are the cell processers in the European PS3s 90nm or 65nm? Is it just the southbridge that is at 65nm?
