Recensione breve del Convertibile Lenovo IdeaPad Miix 720 (7500U, QHD)

Sebastian Jentsch (traduzione a cura di G. De Luca), 04/06/2017

Suerface 3:2. Con il suo display QHD + e il SoC Kaby Lake da 15 watt, il Lenovo IdeaPad Miix 720 rappresenta un concorrente temibile per il Microsoft Surface. Ma le ventole non bilanciate e il microfono di bassa qualità rovinano questo modello da 12" a nostro parere.

Tempi di risposta del Display

I tempi di risposta del display mostrano quanto sia veloce lo schermo a cambaire da un colore all'altro. Tempi di risposta lenti poccono creare sovrapposizioni negloi oggetti in movimento. Specialmente i giocatori patiti del 3D dovrebbero usare uno schermo con rempi di risposta bassi.
       Tempi di risposta dal Nero al Bianco
24 ms ... rise ↗ and fall ↘ combined↗ 14 ms Incremento
↘ 10 ms Calo
Lo schermo mostra buoni tempi di risposta durante i nostri tests, ma potrebbe essere troppo lento per i gamers competitivi.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 26 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (27.1 ms).
       Tempo di risposta dal 50% Grigio all'80% Grigio
45 ms ... rise ↗ and fall ↘ combined↗ 22 ms Incremento
↘ 23 ms Calo
Lo schermo mostra tempi di risposta lenti nei nostri tests e sarà insoddisfacente per i gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 66 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (43.7 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 59 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 4396 (minimum: 43 - maximum: 142900) Hz was measured.

Lenovo ha lanciato la sua risposta al Surface Pro 4 con l'IdeaPad Miix 720, soprattutto perché il rapporto di 3:2 è identico e l'alta risoluzione (2736x1.824 della superficie, 2880x1920 del Miix 720) sono quasi intercambiabili. In termini di display non c'è nulla da criticare, tranne forse la copertura dello spazio colore, ma questo giusto per essere pignoli.

Il vantaggio del Miix è che è dotato di tante porte: 2x USB 3.0 di tipo A, USB Type-C Gen2 con Thunderbolt 3 e poi una fotocamera a infrarossi per Windows Hello. Dal punto di vista tecnico, abbiamo un processore Kaby Lake, oltre a un enorme RAID-SSD, che è veloce.

Purtroppo, il mix 720 non può utilizzare appieno la potenza del SoC, perde il 10% con un carico di lavoro continuo con le applicazioni di uso quotidiano. Questo lo pone allo stesso livello del Surface Pro 4 i7. Anche i modelli significativamente più accessibili, come Aspire Switch Alpha 12 (i5) usano un SoC Skylake che risulta più veloce o semplicemente alla pari.

Lo Switch Alpha 12 con i5 è già disponibile a partire da 750 euro (~ $ 815), il Microsoft Surface Pro 4 + Type Cover (i5-6300U) parte da 1200 euro (~ $ 1304). Ecco la domanda: Perché acquistare il Miix 720 quando le perfomance del processore sono inferiori alle attese?

Il Miix 720 non è certo a buon mercato: il 7500U, 16 GB e 1 TB di SSD costano 1700 euro ($ 1.845). Per la maggior parte degli utenti con preferenze mobili, tuttavia, una piccola versione con 256 o 128 GB e Core i3 o i5 7200U dovrebbe bastare. Questi modelli sono disponibili a partire da 1070 euro (~ $ 1162).

La variante più piccola è sufficiente per godere dei vantaggi docking della Thunderbolt 3, l'autonomia, il grande display, la fotocamera a IR con Windows Hello e la tastiera versatile (illuminata). Molto presto il prezzo scenderà, a 900 euro (~ $ 978) per la versione piccola i3 ed allora sarà un'offerta competitiva.

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

Lenovo has launched its response to the Surface Pro 4 with the IdeaPad Miix 720, mainly because the 3: 2 aspect ratio is identical and the high resolution (2736x1.824 of the surface, 2880x1920 of the Miix 720) are almost interchangeable. In terms of the display there is nothing to criticize, except for the color space coverage perhaps, but this would be a bit too stingy.

The advantage of the Miix is that it is equipped with so many ports: 2x large USB 3.0 Type-A, USB Type-C Gen2 with Thunderbolt 3 and then an IR camera for Windows Hello. On the technical side, a Kaby Lake processor is installed, plus a huge RAID-SSD, which is very fast-paced.

Unfortunately, the mix 720 cannot fully utilize the power of the SoC, 10% is missing during continuous load of everyday applications. This puts it at the same level as the Surface Pro 4 i7. Even significantly more affordable models such as the Aspire Switch Alpha 12 (i5) expect their Skylake SoCs to be faster or just  on par.

The Switch Alpha 12 with i5 is already available from 750 Euros (~$815), the Microsoft Surface Pro 4 + Type Cover (i5-6300U) from 1200 Euros (~$1304). Here is the question: Why buy the Miix 720 when processor performance falls short of expectations?

The Miix 720 is certainly not cheap: The 7500U, 16 GB and 1 TB SSD version costs 1700 Euros ($1845). For most users with mobile preferences, however, a small version with 256 or 128 GB and Core i3 or i5 7200U should also suffice. These are available from 1070 Euros (~$1162).

The smaller variant is enough to enjoy the docking advantages of Thunderbolt 3, the runtime, the great display, the IR camera with Windows Hello and the versatile keyboard (illuminated). Sometime soon the price will fall, with 900 Euros (~$978) for the small i3 version being a competitive offer.
