Recensione breve della Workstation HP ZBook 15u G4 (7500U, FirePro W4190M)

Benjamin Herzig (traduzione a cura di G. De Luca), 10/06/2017

Ultrabook o workstation. La ZBook 15u G4 è una workstation mobile realizzata da HP che - sebbene più economica rispetto ai suoi fratelli - riesce a rispecchiare gli elevati standards di qualità ZBook. Sfortunatamente, questa sottile e leggera workstation ha anche hardware dalle prestazioni basse. Vediamo se questo concept lavora o meno secondo le aspettative nella nostra recensione.

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
22 ms ... rise ↗ and fall ↘ combined↗ 12 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. » 17 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (26.6 ms).
       Tempo di risposta dal 50% Grigio all'80% Grigio
39.6 ms ... rise ↗ and fall ↘ combined↗ 22.4 ms Incremento
↘ 17.2 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. » 42 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.7 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 detected 20830 Hz90 % brightness setting

The display backlight flickers at 20830 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 20830 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 56 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 7168 (minimum: 43 - maximum: 142900) Hz was measured.

Pro

+ case in metallo
+ dispositivi di input comodi
+ poco rumorosa
+ display IPS con luminosità superiore a 300 nits
+ molte porte, comprese VGA e DisplayPort full-sized

Contro

- GPU AMD obsoleta
- CPU non abbastanza potente per una workstation portatile
- copertura del colore troppo bassa per l'editing di immagini
- manca una Thunderbolt 3
- temperature elevate sotto carico
- alimentatore da 65 W troppo debole

Recensione: ZBook 15u G4. Modello fornito da HP.

CPUs U-class ULV e workstations mobile – due cose che non vanno molto bene insieme. La situazione potrebbe cambiare con i prossimi processori Kaby Lake-R ULV quad-core nel 2018. Tuttavia, per il momento non sono disponibili e non stiamo recensendo un ipotetico ZBook 15u G5 ma lo ZBook 15u G4 con Kaby Lake dual-core.

Il G4 copre il necessario. Case in metallo rigido e di alta qualità con dispositivi di input che, sebbene non della stessa classe, sono adatti ad un dispositivo come questo. Le porte includono VGA ed una DisplayPort full-size, e diversamente dal modello di display business HP EliteBook 850 G4 quello dello ZBook 15u G4 nel complesso è decente: IPS invece di TN, ampi angoli di visuale e una luminosità massima superiore a 300 nits.

L'unica pecca è la copertura del colore sotto la media che potrebbe andare bene per un dispositivo business ma non rispecchia gli elevati standards di una workstation. In aggiunta, avremmo voluto una porta Thunderbolt 3 sul dispositivo - di fatto, ce l'aspettiamo su un dispositivo di questo prezzo. La nostra principale critica riguarda le due unità di processo, CPU e GPU. Entrambe sono veloci quanto ci aspettavamo e sono silenziose (coil-whining a parte). Tuttavia, non sono abbastanza potenti per una moderna workstation. Questo si nota in particolare con l'obsoleta GPU AMD FirePro che dovrebbe essere oramai ritirata dal mercato. Invece, una GPU entry-level Quadro come l'M520 o l'M620 sarebbe stata una scelta migliore. Infine, qualche critica alle temperature di superficie elevate del G$ e all'alimentatore non adeguato.

Sensazioni miste: lo ZBook 15u G4 ha un elevato potenziale, rovinato dalla GPU obsoleta e lenta.

La domanda è: a quali utenti punta HP con lo ZBook 15u G4? Gli utenti workstation che vogliono prestazioni troveranno alternative migliori, come il Dell Precision 5520, l'Apple MacBook Pro 15, o anche l'HP ZBook Studio G4 (attualmente in recensione). Poiché hanno batterie più grandi queste alternative offrono anche una maggiore autonomia. Il G$ inoltre non è la scelta migliore se state cercando una workstation economica ma energeticamente efficiente per applicazioni non pesanti - il Lenovo ThinkPad P51s non ha il case in metallo del G4 ma ha una buona batteria opzionale a 6 celle che incrementa di molto l'autonomia. In aggiunta, ha una Thunderbolt 3 e una GPU più veloce Quadro M520.

Considerando il tutto, possiamo solo concludere che lo ZBook 15u G4 è un portatile decente, ma non regge il confronto con altre workstations mobile. Forse il modello dell'anno prossimo costruito sullo stesso chassis monterà CPUs e GPUs più potenti e le cose cambieranno.

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