Das kann man sehen Anhand von zwei dingen.
1. Hardware Spezifikationen der Hersteller
2. Hardware Familie wo der Chip zugehört.
3. Vergleiche von seriösen Internetseiten Anhand der Technischen Daten z.B. hier:
http://xbox360.ign.com/articles/617/617951p1.html
Zu 1:
Technische Spezifikationen beider Konsolen.

Die 360 geht hier in den meisten Spezifikationen als Sieger hervor.
Zu 2: RSX(PS3) = Geforce 7 Familie (7800) ; ATI (360) = nagelneuer Chip. Es gibt im PC-Bereich zu Zeit nichts vergleichbares.
