Il CTO di AMD afferma che l'azienda non ha mai manifestato l'intenzione di implementare il supporto per quattro thread su un singolo core nei futuri processori. L'idea stessa di SMT4 non \u00e8 affatto prematura; molto in questo campo dipende dalla disponibilit\u00e0 di software in grado di sfruttare i vantaggi del multithreading in questa modalit\u00e0. L'azienda IBM, ad esempio, offre da tempo processori server con supporto per questo numero di thread su un singolo core.<\/p>\n

\"AMD<\/p>\n

In un'intervista al sito Tom\u2019s Hardware<\/a><\/noindex> il direttore tecnico di AMD, Mark Papermaster, ha risposto a una domanda sulla possibilit\u00e0 di implementare il supporto per quattro thread per core nel segmento desktop, iniziando il suo commento affermando l'assenza di obblighi ufficiali al momento. Le voci attribuivano ad AMD l'intenzione di implementare il supporto SMT4 nei processori server Milan con architettura Zen 3, ma le presentazioni ufficiali pubblicate in seguito hanno smentito queste informazioni.<\/p>\n

Mark Papermaster ha cercato di discutere della SMT4 in termini il pi\u00f9 astratti possibile, sottolineando il suo desiderio di non associare questa idea ai piani attuali dell'azienda. In queste condizioni, ha valutato questa funzionalit\u00e0 dei processori in modo piuttosto obiettivo. Secondo lui, nel segmento desktop alcuni utenti disattivano anche il multithreading dei core. Alcune applicazioni traggono vantaggio dall'uso di tale funzione, altre no. La stessa concezione dell'elaborazione di quattro thread su un core non \u00e8 nuova; \u00e8 stata utilizzata da tempo nel segmento dei server. Mark ha persino citato l'esistenza di soluzioni hardware con supporto per SMT4, accennando ai processori IBM Power, che hanno acquisito questa funzionalit\u00e0 all'inizio di questo decennio. In sostanza, come afferma Mark, la giustificazione per l'implementazione di SMT4 \u00e8 determinata solo dalla presenza di una massa critica di applicazioni che possono lavorare efficacemente con essa in un segmento di mercato specifico.<\/p>\n
