45nm? I thought this was coming this year for the PS3?

45nm RSX is coming out February next year I think, 45nm Cell is already out I think, I think they are working on the 32nm Cell....

 

 

yes.

but i guess mass production won't be here til end 2009

I don't get it.

Why doesn't Sony (or whomever for that matter) just rush to make the 32nm Cell or RSX?

Why do they have to go down sizes in increments?

Couldn't they have went straight from 90nm to, say, 45nm for example?

 

because the manufacturing plant or fabrication plant do not currently have the technology to make 32nm chips... and as Sony currently donot have any of their own fabrication plant therefore they have to follow the market ...

Secondly if u try to skip one generation then there is a very large change that you will get stuck and u might take more time in the end... making small incremental jump keep providing feedback to ur research... Intel saw large increase in 90nm P4 power leakage and they managed to control it in 65nm.. had they made a direct jump to 65nm without going into 90nm they would have taken much longer to sort out the problem.. making small jumps minimizes the risk factor.

Btw i believe Sony president somewhere said that they will be having the 45nm Cell in the PS3 before the end of the yr... but i m not sure when and where and did he exactly mean this.. but if they manage to pull this off then sure we will see a price drop right before the christmas

i guess end of 2008/early 2009 is a realistic date for 45nm cell. ibm allready has the cell shrinked to 45nm, so you just need to get mass production for it on the way. ibm is using same soi production process for the cell that amd uses for their cpus and amd is planning to ship first 45nm server chips in q4 2008, so it should be safe to assume that ibm should have mass production for the cell in 45nm running about the same time.  add 1-2 months till the chips get into consoles, and you end up with end of 2008 early 2009 date.
