\u00c8 passato pi\u00f9 di un anno dalla scoperta di Spectre e Meltdown, e il mercato dei processori \u00e8 stato scosso dalla scoperta di nuove vulnerabilit\u00e0 legate ai calcoli speculativi. I chip pi\u00f9 colpiti sono stati, incluso<\/a><\/noindex> l'ultima<\/a><\/noindex> ZombieLoad<\/a><\/noindex>, che ha colpito i chip Intel. Certamente, AMD ha colto l'opportunit\u00e0 per mettere in evidenza la sicurezza dei suoi CPU.<\/p>\n

\"AMD<\/p>\n

Su pagina<\/noindex>, dedicata alle vulnerabilit\u00e0 simili a Spectre, l'azienda ha orgogliosamente dichiarato: «In AMD sviluppiamo i nostri prodotti e servizi tenendo conto dei requisiti di sicurezza. Sulla base di un'analisi interna e di discussioni con i ricercatori nel campo della sicurezza, riteniamo che i nostri prodotti non siano soggetti ad attacchi Fallout, RIDL<\/a><\/noindex> o ZombieLoad<\/a><\/noindex> a causa della presenza di verifiche hardware di protezione nella nostra architettura. Non siamo riusciti a riprodurre queste vulnerabilit\u00e0 sui prodotti AMD e non abbiamo dati che suggeriscono che qualcun altro ci sia riuscito». Si riporta che le CPU AMD sono immuni a un ulteriore attacco MDS<\/a><\/noindex> — Store-to-Leak Forwarding<\/a><\/noindex>.<\/p>\n

A causa della crescente scoperta di nuove vulnerabilit\u00e0 e della necessit\u00e0 per i produttori di installare le relative patch, i processori AMD possono rivelarsi pi\u00f9 performanti rispetto alle soluzioni concorrenti, secondo un recente studio indipendente uno studio<\/a><\/noindex>, secondo un'indagine condotta dal sito Phoronix, l'applicazione di un ampio spettro di correzioni per il complesso di vulnerabilit\u00e0 dei processori legato ai calcoli speculativi porta a una riduzione delle prestazioni delle CPU Intel in media del 16% (disattivando l'Hyper-Threading — fino al 25%). Nel caso dei processori AMD Zen+, le prestazioni in queste stesse condizioni calano solo del 3%.<\/p>\n

<\/center>
\n\"AMD<\/p>\n

Peggio ancora: Apple e Google consigliano<\/a><\/noindex> agli utenti Intel di disattivare completamente l'Hyper-Threading, il che pu\u00f2 comportare una riduzione delle prestazioni a volte fino al 40–50 % (a seconda del compito). La stessa Intel raccomanda di non farlo<\/a><\/noindex> nella maggior parte dei casi, ma il problema pu\u00f2 risultare particolarmente critico per workstation, server e altre aree sensibili a prestazioni e sicurezza. Nel caso dei chip AMD, non \u00e8 necessario disattivare una tecnologia simile chiamata Simultaneous Multi-Threading. Inoltre, il flusso di notizie sulle vulnerabilit\u00e0, comprese le informazioni su i tentativi di Intel di nascondere le informazioni<\/a><\/noindex> al pubblico non possono non influenzare l'immagine dell'azienda.<\/p>\n

Queste notizie arrivano in un momento particolarmente difficile per Intel: AMD sta per lanciare una famiglia di moderni processori a 7 nanometri con architettura Zen 2 per applicazioni desktop e server. Nel frattempo, Intel utilizza ancora una tecnologia molto datata (in termini di evoluzione del processo) a 14 nm e non riesce a dare avvio alla produzione di massa di chip a 10 nm. Tutto ci\u00f2 avvantaggia AMD, che sicuramente continuer\u00e0 a guadagnare quote di mercato.<\/p>\n
