ralexand said:My point though was that the bandwidth in the chip shouldn't hamper from using spe in development now since the structure of the chip will likely remain unchanged.
He was saying that bandwidth to the GPU would hamper using the CPU for graphics currently. According to watch impress, the current dev kits have 2GB/s total between Cell and the G70. If that's split both ways, that's 1GB/s from Cell to the GPU. 1/20th of the final machine going to RSX (1/15 of the final machine going back to the CPU).
So computationally there'll little obstacle, but in terms of getting the data from A to B, currently there is.
I think beyond technicalities of the early dev kits, I think the greater obstacle for first generation games will be the necessity to simply get everything else working well on the CPU first. Graphics on Cell likely won't be a priority for any first gen game - you gotta get all the "normal" things working first before you can even think of dabbling with "nice" things.
