Switching out a 90nm GPU for a 65nm?
So it seems that the early models of the PS3 used a 90nm GPU, which was then shrunk to 65nm for the latter fat PS3, then also used on the first models of the slim PS3, and then later shrunk once more for the latest models of the slim PS3 that now use a 40nm GPU.
I take it that using a slim GPU in a fat is likely impossible, but since the fat models used 2 differently sized GPU, I was wondering if it was possible to switch the GPU of an early 60gigs unit from a 90nm to a 65nm from a more recent (but still fat) PS3.
Is this possible at all? Has anyone tried it? I'd like to know an answer with certainty rather than a mere guess, so if anyone has tried it already, I'd definitely like to hear from them. Thanks.
