Спецификации консолей: Xbox 360 vs PS3 (Раунд 1)

Как же все радужно выглядит на бумаге, все консоли имеют невероятный потенциал, но когда дело доходит до игр, то потенциал уходит. Производительность оказывается не такой большой, а проблем все больше и больше. Итак перед вами сравнение производительности гпу обоих консолей "на бумаге": Xenos(X360) VS. RSX(PS3). Первый раунд начался, да начнется версус.
