Forums - Sony Discussion - Sony is phasing out the 60 gb to be replaced by the 80gb

Oh, sorry, the EE+GS were one chip as your second picture shows. Both are gone in the newer PS3. EE is the Emotion Engine (Physics + CPU) and the GS was the Graphics Synthesizer. They consolidated them to one chip. There's really no need to keep the GS without the EE since the new RSX replaces the GS. Think of it like an nVidia 5500 vs an nVidia 7900, the RSX handles everything the old GS would seamlessly. They are direct descendants. Now, as far as backwards compatibility, all Sony has to do is change the calls for the old GS to run off the RSX and all the old EE calls to the Cell in a wrapper functions on the PPU and a SPU or two if needed.

 

Running the GS on RSX is like running an old DirectX/OpenGL game on a new DirectX/OpenGL card.


What you wrote could not be farther from the truth. Seriously.

It was widely suspected that the GS was removed since the EE/GS was one chip. However, this is not the case. The GS was simply kept by itself and moved to a slightly different location.

Regarding the RSX, it could not take over the GS's job. Your analogy about 5500 v 7900 is a very bad one, especially since they are not direct descendants by any means. Getting the RSX to take over the GS task would be impracticle since true software emulation can do it far easier, and likely with better results.

Basically, the GS does some really screwy stuff, especially with how it works with memory that would be very difficult to emulate. Thus they decided to keep the GS, or a variant therof, in the PS3 to make emulation much easier and gain better compatibility.

Then again, it looks as though they may integrate the GS in the RSX. So you were right, but not in the sense you intended. According to a couple of reports, Sony has pretty much quite working on the software BC beyond bugfixes and the like. This likely means that the GS will never be fully emulated and later integrated into the RSX.

 Ah, I guess I was wrong.  Last I read, nobody new what the CXD2972GB chip was on the far side of the board.  When I read about it it was estimated that it was a hardware scaler chip.  I still don't buy the idea that the RSX couldn't emulate the GS, but I assume they had a reason for keeping it and that seems logical enough.



It seems the mods need help with this forum.  I have zero tolerance for trolling, platform criticism (Rule 4), and poster bad-mouthing (Rule 3.4) and you will be reported.

Funny how people post what seems to be a list of true technical details when it turns that they actually didn't have a clue if what they were saying was real or not.

Really I mean how much can this emotion chip be? Like 5 cents I guess. It is a chip that has already been designed on silicon, so how much could it really cost.
The only logical thing that comes to my mind is that sony can to the backward compatibility with software, so they don't think they need this chip anymore. I really don't understand what all this fuss about backward compatibility is anyway, you probably still have your ps2 if you bought a ps3 so??

 

also @eatrice 

While what you say is mainly true, but people don't wait for a final version for pc's do they. If sony keeps up increasing the hard disk and keeping the price the same, I guess they will start buying it anyway. 


I think the estimates for the cost of the EE was around $20(it's not just one chip BTW). Me personally, I do not have my PS2 any longer, gave it to a friend for his kids. I haven't heard any kind of outcry from people without the EE chips, mainly EU here, so the software BC must be working fairly well.

 As for a "final" version, didn't the PS2 go through like 20-25 different chipsets since there were no firmware updates then? They were just not widely known like they are now.
