HP Pro Tablet 408 G1 Tablet Review

Sascha Mölck, Tanja Hinum (translated by Liala Stieglitz), 02/27/2016

Interesting. An 8-inch Windows tablet that is furnished with Windows 8.1 and a Bay Trail processor is no longer awe-inspiring in 2016. Particularly since the device is aimed at professional users. Nevertheless, the tablet is compelling. Not least thanks to its good battery life and the integrated 3G modem plus a monthly data volume.

For the original German review, see here.

HP's Pro Tablet 408 G1 is an 8-inch Windows tablet primarily aimed at professional users. The installed Bay Trail processor is no longer brand new. The Cherry Trail successors have been on the market for months now. However, the latter do not provide a much higher performance at the same clock speeds since the architecture of both CPU generations are not very different. Not many direct opponents are found in our database. Devices such as Dell's Venue 8 ProGoogle's Nexus 9Apple's iPad Mini 4Samsung's Galaxy Tab S2 8.0 LTE can be named here.

Case & Connectivity

The tablet's entire casing is made of black plastic. The device does not exhibit any manufacturing flaws. However, it could be a bit stiffer. It warps much too easily. The back is snapped on, i.e. not glued or screw-fixed. The micro-SD and SIM card slot as well as the battery are found behind it. The tablet carries the interfaces that we are used to in other 8-inch tablets. A micro-HDMI port enables connecting an external monitor. The micro-USB port is also the power socket. The 1-meter (~3 ft) charging cable is a bit too short. However, since HP relies on a USB solution, the user could use a cable from another manufacturer.

A SIM card is in the tablet's box. It can be used immediately. The tablet's buyer additionally receives a monthly data volume of 200 MB for a period of 3 years. The volume can be used in all European countries that offer HP Mobile Connect. The volume can be increased for a surcharge. HP offers other plans that can be used in Europe (also those that do not offer Mobile Connect) and worldwide. The included SIM card can be used, but it is not a must. SIM cards from other common network providers/resellers can be inserted. The tablet supports micro-SIM cards.

The installed processor is a 64-bit model. However, HP preloads the 32-bit version of Windows 8.1 on the tablet. The reason: The 32-bit version is easier on resources. We upgraded to Windows 10 for a test. That was not a problem. Windows 10 identified every hardware component and they can be used.

Input Devices

The tablet is furnished with a capacitive touchscreen. It supports both stylus and 10-point touch entries. The screen responded instantaneously to inputs and we did not encounter problems. A stylus for the tablet is not included, and has to be purchased separately. It costs about 50 Euros (~$55). Inputting via stylus is easy. It is a pressure sensitive model by Wacom.

The 8-inch screen in HP's tablet has a native resolution of 1280x800 pixels. The panel pleases with a decent brightness rate (332.8 cd/m²) and outstanding contrast (3155:1). The screen exhibits PWM flickering at a frequency of 378 Hz in brightness levels of 40 percent and lower. That could lead to headaches or eye problems in sensitive users.

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 378 Hz ≤ 40 % brightness setting

The display backlight flickers at 378 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 378 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9813 (minimum: 43 - maximum: 142900) Hz was measured.

The screen has a DeltaE 2000 shift of 5.45 in delivery state. It is not far from the target range (DeltaE less than 3). The screen does not have a bluish tint. Calibrating the screen should improve the rates.

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
33 ms ... rise ↗ and fall ↘ combined↗ 13 ms rise
↘ 20 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. » 85 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.5 ms).
       Response Time 50% Grey to 80% Grey

The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 12 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (40.7 ms).

HP furnishes the tablet with a viewing angle stable IPS panel. Thus, the screen remains legible in every position. The tablet can be used outdoors, but direct sunlight should be avoided.

Performance

HP's Pro Tablet 408 G1 is an 8-inch business device. It has enough computing power for applications from the office and Internet fields. Stylus inputting is also possible (the corresponding pen has to be purchased separately; approximately 50 Euros/~$55). A 3G modem is also installed. Our review sample costs almost 400 Euros (~$438). A somewhat cheaper model with a 32 GB eMMC storage is also available for approximately 330 Euros (~$362).

Processor

Intel's Atom Z3736F (Bay Trail) quad-core processor is inside the tablet. It is a frugal model with a TDP of below 4 watts. Thus, the processor can be cooled passively. The CPU clocks at a base speed of 1.3 GHz, which can be boosted to 2.16 GHz via Turbo. The processor performed our CPU test at 1.58 to 2.16 GHz (single thread) and 1.58 GHz (multithread). Its behavior is identical in both AC and battery mode.

System Performance

The tablet runs smoothly; we did not encounter problems. The PCMark benchmark scores correspond to the installed SoC's performance. Comparable devices furnished with Cherry Trail processors (Bay Trail successors) score better. The reason: They carry much stronger GPUs. The system performance of HP's tablet cannot be further increased.

Storage Device

Data is stored on an eMMC module with a capacity of 64 GB. The user has about 47 GB available for personal use. The storage device's transfer rates lag slightly behind its potential because the drive is encrypted. The transfer rates increase when encryption is disabled. The storage capacity can be expanded via a micro-SD card.

Graphics Card

Intel's HD Graphics graphics core supports DirectX 11, and clocks at speeds up to 646 MHz. The 3DMark benchmark scores are on a normal level for the GPU installed here. Faster clocked versions of the graphics core exist, and they achieve correspondingly better scores. In any case, the results are at the lower end of the performance scale. The core cannot even compete against AMD's weakest GPUs (Radeon R2Radeon R3).

Temperature

The tablet performed our stress test (Prime95 and FurMark run for at least one hour) in the same manner in both AC and battery mode. The processor already throttles in the first minutes: It drops from 1.58 GHz to 1.33 GHz. Throttling gradually continues in the further course until a speed of 500 MHz is reached. It looks similar with the GPU. Its final speed is 300 MHz. The tablet heats up palpably despite the low speeds. Forty degrees Celsius (104 Fahrenheit) are surpassed on several measuring points.

Speakers' Pink Noise

The tablet's stereo speakers are situated on the device's underside. They produce a decent sound that lacks bass. The combo audio jack enables connecting headphones or external speakers.

Power Consumption

The energy requirement is on a normal level for the installed hardware over the entire load range. The rates are unusually high, and we could not exclude recharging the tablet during the measurements. However, the battery status displayed 100%, no charging. The Wi-Fi runtime also indicate a lower consumption, but it could be due to an inefficient or semi-defective power supply. The power consumption of this tablet hardware should be a good 3 to 5 watts lower especially while idling.

HP's Pro 408 G1 tablet is primarily aimed at professional users. The installed processor is suitable for basic applications from the office and Internet fields. The tablet runs noiselessly and barely heats up in routine use. It offers a good battery life and comes with a 3G modem including a monthly data volume of 200 MB for three years. The screen also pleases: It is bright, viewing angle stable and has an outstanding contrast. Unfortunately, HP only gives a 12-month warranty on its tablet.

HP offers an overall interesting device here. The combination of Windows 10 (upgrading is free), 3G modem (including a monthly data volume), 64 GB storage, a decent battery life and optional stylus inputting also makes the tablet attractive for private users. However, the high price will deter many potential customers from buying it.
