Aggiornamento

AMD ha inoltre presentato, in corrispondenza dei nuovi Catalyst 9.1, anche una versione speciale per il modello Radeon HD 4850 X2. Sapphire, l'unico partner di AMD ad aver immesso sul mercato questo tipo di schede, ha infatti sviluppato la 4850 X2 di propria "iniziativa": il colosso californiano non ha infatti mai fornito indicazioni per la creazione di tale tipo di scheda, per questo motivo è stata esclusa, inzialmente, dalla lista dei modelli supportati con i nuovi Catalyst. È ora invece possibile scaricare, sempre dalla pagina ufficiale di download la versione specifica per questa scheda.
