OMG!!!CELL can do realtime RAYTRACING with just software!!!!

Well, the Cell was more or less designed to do such works as raycasting, but it will not be used in the PS-3 in this way. Furtheremore real test cases already had the tendency that the single programms of one node did not fit into its 512 KB of internal Ram. Only this memory is dedicated to the SPE. It has nothing to do with the RAM that is dedicated to the Cell itself. If the cell has to work with more than these 512KB of memory it has to wait till the missing code is loaded from the 256 MB of memory, which takes several cycles as on every other processor, too. In fact this was probaly a reason why they chode a raycasting demo. Many people don't realize the difference between raycasting and raytracing, but raycasting is much easier and faster than an raytracing algorithm, which would probably not fit into the internal 512 KB RAM and it would not work realtime.

Very nice.... except the PPE alone can grab 4 instructions from the XDR and write 2 in a single cycle. The PPE has 512k cache while "EACH" individual SPE has 256k of ram. It is referred to as ram because it allow the programmers to control how information is stored and handle by the SPE's.
