Breve Análise do Portátil HP ProBook 645 G4 (Ryzen 5 Pro 2500U, SSD, FHD)

Name: HP ProBook 645 G4 3UP62EA
Brand: HP

No ar. O ProBook 645 G4 vem com uma poderosa APU AMD, bons dispositivos de entrada e um rápido SSD NVMe. Apesar de seu preço de 900 a 1000 euros ($1.051 a $1.167), o dispositivo não está livre de falhas: O portátil oferece uma duração pobre da bateria e uma tela escura com uma relação de contraste pobre.

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

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

100 Hz

≤ 30 % brightness setting

The display backlight flickers at 100 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 30 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 100 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8746 (minimum: 5 - maximum: 343500) Hz was measured.

Display Response Times

ℹ

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

↔ Response Time Black to White
26 ms ... rise ↗ and fall ↘ combined	↗ 16 ms rise
26 ms ... rise ↗ and fall ↘ combined	↘ 10 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 59 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
33 ms ... rise ↗ and fall ↘ combined	↗ 14 ms rise
33 ms ... rise ↗ and fall ↘ combined	↘ 19 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 40 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (32.9 ms).

The HP ProBook 645 G4 3UP62EA, review device provided courtesy of: HP Germany.

O ProBook 645 G4 é um portátil empresarial de gama média. Aqui a HP oferece uma carcaça completamente nova. Aqueles que esperam materiais de alto valor ficarão desapontados: A carcaça é feita inteiramente de plástico. Somente dispositivos de gama alta como o HP EliteBook 745 G1 oferecem uma carcaça de metal.

O portátil vem com uma APU Raven Ridge da AMD, que oferece desempenho mais que suficiente para todos os aplicativos atuais. A parte da CPU da APU fornece o mesmo nível de desempenho que os concorrentes baseados na Intel.

A GPU integrada oferece mais desempenho do que a solução da Intel (UHD Graphics 620) e pode executar muitos jogos com taxas de quadros fluentes. No entanto, a maioria dos jogos modernos é jogável apenas com resoluções e configurações baixas. Infelizmente, a HP não utiliza a GPU 100%, porque o sistema funciona no modo de canal único. Aqui, recomendamos a instalação de um segundo módulo de RAM para ativar o modo de canal duplo.

Um SSD NVMe resulta em um sistema muito responsivo. É possível substituir o SSD No entanto, para isso, um terá que remover a tampa inferior. Além de um SSD M.2-2280, um disco rígido de 2,5 polegadas também pode ser instalado dentro do ProBook 645 G4. Nosso dispositivo de teste não oferece um modem LTE. Dito isto, um modem LTE pode ser facilmente instalado após a compra. O teclado deixou uma impressão muito positiva. Está apto para a digitação regular. Infelizmente, não possui luz de fundo. No entanto, uma luz de fundo do teclado está disponível como um recurso opcional.

O ProBook revela falhas que um portátil de negócios não deveria ter.

A tela IPS mate conta com bons ângulos de visão No entanto, também possui um brilho de tela baixo e uma baixa relação de contraste. Um portátil que custa 900 a 1000 Euros (~$1.051 a 1.167) deve oferecer mais a esse respeito. A duração da bateria é fraca. Em nosso teste de Wi-Fi praticamente orientado, o ProBook dura menos de 5 horas. Aqui, o portátil deveria ter durado pelo menos 2 a 3 horas a mais.
