AMD ha da poco annunciato i primi tre processori Ryzen basati sull’architettura Zen. L’annuncio è stato fatto in occasione del ’evento Tech Day di San Francisco durante il quale, appunto, l’azienda ha svelato specifiche, prezzi e disponibilità della serie high-end Ryzen 7, ovvero quella che competerà contro i Core i7 di Intel. Le CPU di fascia media (Ryzen 5) e bassa (Ryzen 3) verranno invece presentati nei prossimi mesi.

AMD

I processori Ryzen, realizzati con tecnologia di processo a 14 nanometri, integrano 4,8 miliardi di transistor. La serie Ryzen 7 è costituita dai modelli 1800X, 1700X e 1700, tutti con otto core e sedici thread (Simultaneous Multi-Threading). Le frequenze di clock sono 3,6 GHz (4 GHz turbo), 3,4 GHz (3,8 GHz turbo) e 3 GHz (3,7 GHz turbo), mentre i TDP sono 95, 95 e 65 Watt.

I prezzi consigliati dall’azienda stessa sono, rispettivamente, 499, 399 e 329 dollari, cifre molto inferiori a quelli dei Core i7 corrispondenti. Tutte e tre le CPU arriveranno sul mercato il 2 marzo, ma già da adesso è possibile ordinarle presso i rivenditori autorizzati.

L’obiettivo di AMD era incrementare il numero di istruzioni per clock (IPC) del 40%. L’azienda è invece riuscita a superare il target iniziale, ottenendo un miglioramento del 52%. Secondo i test condotti, il Ryzen 7 1800X è il 9% più veloce del Core i7-6900X nel benchmark Cinebench R15 multi-thread mentre il Ryzen 7 1700X supera il Core i7-6800K con un +39%.

Il Ryzen 7 1700 è stato invece definito invece il processore ad otto core con i consumi più bassi del mondo. Questo è anche l’unico processore dei tre ad essere venduto anche in versione boxed con dissipatore Wraith Spire.

    Fantastic blog! Do you have any suggestions for aspiring writers?

    I’m planning to start my own website soon but I’m
    a little lost on everything. Would you suggest starting with a free platform like WordPress or go
    for a paid option? There are so many choices out
    there that I’m totally confused .. Any recommendations?
    Cheers!
