Il Razer Core V2 e il Blade Stealth: un team perfetto.
Il Razer Core V2 e il Blade Stealth: un team perfetto.

Con ogni probabilità, il Blade Stealth attirerà poche persona. Sebbene Razer sia associata al gaming e dia l'impressione di aver lanciato un buon portatile gaming sul mercato, con il suo chip grafico Intel-UHD-620 il Blade Stealth non è abbastanza potente per un vero giocatore. La maggioranza dei giochi attuali che richiedono maggiore potenza grafica con livello medio di dettagli. E il Razer non rispecchia le attese degli utenti che vogliono maggiore autonomia, l'assenza di un display matto, e le poche connessioni fanno il resto. 

"Laptop di giorno day, desktop di notte." Razer conosce le necessità tra i due diversi gruppi di clienti. Il Blade Stealth sicuramente è interessante unitamente con il Razer Core V2 per i giocatori notturni. 

Il Core con scheda grafica esterna sostituisce completamente l'UHD 620 interna tramite la connessione Thunderbolt 3, offrendo un buon incremento di prestazioni con tutti i giochi. L'abbiamo già testata a lungo in passato. Come esempio, usiamo il gioco "Resident Evil 7" con dettagli elevati (1920x1080 con AF, FXAA, e TAA): mentre il Razer Blade Stealth arriva ad un livello di appena 10 FPS con la Intel UHD 620, il frame rate con la Razer Core V2 e la Nvidia GeForce GTX 1050 esterna ha un incremento dell'82% arrivando a 56 FPS. I 40 Gbit/s della porta Thunderbolt difficilmente rallenta la situazione, in quanto la stessa scheda grafica arriva a circa 59 FPS nella configurazione desktop. A breve pubblicheremo una recensione della Razer Core V2 e della Blade Stealth con tutti i risultati benchmark dei giochi attuali, evidenziando le differenze tra monitor interno ed esterno.

Nota: si tratta di una recensione breve, con alcune sezioni non tradotte, per la versione integrale in inglese guardate qui.
