JVD <shakes head> You can't really be serious that it's not a foregone conclusion that the R500 is based on 90nm? Anything better than that is wishful thinking.

They can use 80nm or mabye even 65nm
IF Xbox2~Xenon main memory bandwidth is under 30 GigaBytes per second, then it is essential that there be another pool of higher bandwidth memory. eDRAM or some form of embedded memory. not counting the usual caches found in all CPUs and GPUs
If the system is shipping end of 05 i would expect them to put in 700mhz gdr ram . That shouldn't be very expensive (they are using 660mhz in the x800xt pe ) or perhaps they will use a fatter pipe
