Forums - Sony - Does any know about the 45nm PS3?

The heat reduction will probably be negligable. Its essentially diminishing returns unless they spend the money to redesign the internals of the chip.

Go directly to physics II, do not pass go, do not collect $200.

As for looking at the power graphs for the Cells progression. The low end of the graph in terms of power consumption remains relatively steady whilst the upper limits say 4Ghz+ frequencies require far less voltage to obtain as the process nodes move from 90 -> 65 -> 45nm.

Found it.



Tease.

I see a graph with a near halving of "Power" (whatever that means) at 3.2 GHz.

Just shrinking the Cell in the PS3 isn't going to really net a significant power saving at this point. Its just one of many components which consume a moderate quantity of power which is what I was trying to get at.
