Da POWERCOLOR la HD 2900 Pro 512 MB GDDR3
-
Dopo l'iniziativa di altri produttori quali Sapphire, HIS, GeCube, anche POWERCOLOR presenta la sua Radeon HD 2900 PRO, le caratteristiche sono identiche come per lo stesso modello degli altri produttori, Vi ricordiamo che si tratta di una scheda identica alla sorella maggiore HD 2900 XT, ma con frequenze inferiori, il chip del core è stato portato a 600 MHz e come già detto mantiene tutte le caratteristiche di R600, invece le memorie sono portate a lavorare ad un frequenza di 800 MHz (1600 MHz in modalità Double Data Rate) in quantitativo di 512 MB e un bus di interfaccia a 512 Bit, naturalmente supporto alle nuove librerie DX10 e SM 4.0

Questa vanta un prezzo/prestazioni molto conveniente!:n2mu:
Ciao;)

scusate , ma se la 2900xt si avvicina alla gtx come fa la pro ad essre un po sopra la 8600gts? ? ? ? ? ? ? ? ? la si clocca un po e via....magari si cloccano anche gli shader....

Molto interessante, la tengo in considerazione.
