Here is a new breakdown by iSupply.
Don´t know the validity of it.
However, what I think is quite interesting is that the price of the RSX is so big.
In this price the DDR3 DRAM is included but still it really stands out in my opinion.
However this rhymes pretty well with the fact that the RSX is in line for the next die shrink and the 45 nm version should be in production at Toshibas factories since some time. If the next PS3 revision replaces both the 512 mbit XDR and DDR3 DRAM with 1 Gbit XDR DRAM I think they could shave off another $20 just on the RSX and the memory chips. It will be very interesting to see when it shows up in the PS3.
