Kısa inceleme: ThinkPad E480 (i5-8250U, RX 550) Laptop

Benjamin Herzig, 02/10/2018

Çok sıcak. 2018 yılının ilk ThinkPad modeli gerçek bir fiyat/performans kazanını. Belki de Lenovo için çok iyi satan bir cihaz olacak. Ama gerçekten alınması gereken bir model mi?

Display Response Times

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
31.2 ms ... rise ↗ and fall ↘ combined↗ 17.2 ms rise
↘ 14 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 78 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.5 ms).
       Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined↗ 22.8 ms rise
↘ 21.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 62 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.3 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 24880 Hz40 % brightness setting

The display backlight flickers at 24880 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 40 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 24880 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9024 (minimum: 43 - maximum: 142900) Hz was measured.

ThinkPad E480 güçlü bileşenlere ve makul bir fiyata sahip bir cihaz. Ancak sadece bileşenlere bakıp karar vermemek gerek. Nihayetinde asıl önemli olan pratikteki performans.

E480 kendinden söz ettirecek birçok iyi değere sahip. Elden geçen kasası da bunlardan biri. Kalitesiyle tatmin edici. Aydınlatmalı klavye oldukça iyi. Trackpoint ve touchpad de kullanışlı. Bağlantı olanakları yönünden de herhangi bir sorun gözükmüyor. Dilerseniz 2 RAM ve bir adet SSD slotu da boş bırakılmış. Ekran parlak değil, ama mat IPS ekran kontrast değeri ile çok fazla eleştiriye yer bırakmıyor.

Zayıf yönleri ise SD kart slotu yerine MicroSD kullanılması, kullanılan SSD modelinin yavaş olması olarak sıralanabilir. Ancak en büyük zayıflık soğutma sisteminde. Performans düşüşleri bir yana kasanın dışında 71.6 dereceye kadar sıcaklık ölçmek mümkün. Cihazı kullanırken eldiven takmak belki bir çözüm olabilir. Bunun dışında ortalama batarya ömrü, batarya kullanımında grafik performansının düşüşü gibi konular oldukça alakasız kalıyor.

Eğer bir yerlerinizi yakmak istemiyorsanız AMD grafik çözümü kullanan modelden uzak durun.

Fiyat-performans oranı ne kadar iyi olursa olsun, bu bileşenlerle E480 önerilebilecek bir durumda değil. Elbette ölçtüğümüz sıcaklıklar test ortamında ve test koşullarında, ama bu değerlere sizin de gündelik ortamda ulaşmanız mümkün olabilir.

E480 gerçek anlamıyla bir potansiyeli olan cihaz, ama böyle bir sonuca ulaşmak tam anlamıyla hayal kırıklığı. Intel UHD 620 kullanan modeller bu konuda daha iyi olabilir.
