pero como yo estaba de paso le hago la suplencia y paso la noticia de turno "dumeante" para PS3

[quote]Lee went on to question whether the PlayStation 3's Cell processor "is as well designed for game development as Sony would have you believe... Some aspects of the SPEs, such as the lack of branch prediction, make them particularly unsuited to running most game code, which contains a lot of branches."
Cell carece de predictor y eso hace que los SPE sean de poca utilidad para la mayoria de codigo de juego.
[quote]"They appear to be designed more for serialised streaming math code, more common in video codecs and audio processing, the traditional domain of digital signal processing chips... [It] seems like a lot of overhead is needed to feed work units to the SPEs and copy the results back to system memory."
Cell esta mas designado para streaming, para manejar codecs de video, procesos de audio, etc
[quote]Lee also said that he believes porting games from the Xbox 360 to PS3 will be "reasonably difficult", since "the Xbox 360 has a lot more general purpose processing power that can be flexibly reallocated, and all of the Xbox 360 CPU cores have equal access to all memory. The asymmetric nature of the Cell could easily lead to situations where the game has too little of one type of processing power and too much of another."
Portar juegos de 360 a PS3 sera complicado porque 360 tiene mas capacidad de proceso " de fines generales" que puede ser ubicado con mas flexibilidad y que cada Core de 360 tiene igual acceso a la totalidad de la memoria. La naturaleza asimetrica de CELL conduce a situaciones donde se tiene mucho de un proceso pero poco de otros.
[quote]"And the content might suffer as well, since you'll never see a PS3 title with more than 256MB of textures at any given time, due to the split graphics and system memory banks."
Y el contenido sufre mas, en PS3 tu nunca veras un juego que use mas de 256 Mb de ram en texturas al mismo tiempo porque los bloques de memoria estan divididos en logica y video.
Y bueno... aqui esta la fuente... y no es un blog para que luego no digan que...
