- Yes Sony could use an updated Cell and I wouldn't be surprised considering they bought Toshiba's Cell manufacturing plant.
- This would be a good idea but Sony don't like paying for the expense of high end GPUs.
- You mean multiple cores? The Cell didn't have multiple cores, it had a single one and 8 vector units. 1 disabled, 1 reserved.
The RSX is a modified/crippled GTX 7800. It's absolutely ancient history by computer standards. They would have no reason to use an 'updated' version of that since that technology and it's successors have been replaced many times over. There were 8800/9800, GTX 280, GTX 480 and GTX 580 series. If Sony do decide to go with nVidia whatever the PS3 uses will be based on the 680 or 780 series.
Er, I meant whatever the PS4 uses.
I guess I'll go in order. As far as overall processing power goes the entire PS3 is easily outpowered by a single piece of hardware now and has been for a long time. The whole super computer exaggeration is equally as silly as calling a spark from a static shock a lightning storm. You could have a giant room packed with PS3s linked together to form a super computer and it still wouldn't come anywhere close to proper supercomputers. For anyone who doesn't know, yes that's what a supercomputer is, a ton of computers linked together.
