leo-j said: I was impressed when I saw this today in gametrailers. They are using 6 spe's of the cell, (3 ps3's because they are using 2 spe's of each one ps3 has 8, and 7 usable) and they are rendering a full car. Wihtout using the GRAPHICS CARD. http://www.youtube.com/watch?v=oLte5f34ya8 |
They aren't using 2 SPEs from each PS3, they're using all available SPEs from all three PS3s. When he puts the light/dark filter over the image, you can see how the rendering workload is broken up. Cell has 8 SPEs, 7 of them are working in a PS3, and one is reserved for I/O, so 6 are available to programmers. One is used for image compression to send data over the network, the other 5 are used for raytracing. On the client, one of those 5 is used to decompress the compressed images sent from the other PS3s, so in total, 14 SPEs are doing raytracing to produce a 720p image with 4x supersampling.
