arquitectura ps3/360

Buenas!

Veréis, voy a ha hacer un pequeño trabajo sobre la arquitectura de estas dos consolas y necesito obtener el máximo de información técnica de ambas arquitecturas... memoria, cpu, gpu, etc...

También me gustaría que habláramos un poco de ambas arquitecturas, cual es mejor y porque, cuellos de botella que tengan ambas, etc... En especial me interesa el tema CPU/GPU/MEMORIA más que el tema blu-ray vs dvd, aunque si alguien quiere decir algo de esto pues también será bienvenido.

Empiezo aportando las especificaciones técnicas que he encontrado de ambas máquinas (más adelante las intentaré poner en dos tablas para compararlas una a una y me curraré un poco más el post, que mañana tengo examen xdd):
