HP Pro x2 612 G1 Convertible Review

Sascha Mölck, Tanja Hinum (translated by Andreas Osthoff), 03/01/2016

Business hybrid. HP's 12.5-inch detachable is designed primarily for business users. It is designed to be tablet and notebook in one device, and it actually works pretty well. However, you will not get the latest components. The device has been available since the summer of 2014 and has not been updated.

For the original German review, see here.

HP's Pro x2 612 is a business detachable with a 12.5-inch screen. The underlying hardware platform has not been updated since its launch in the summer of 2014, so we are still dealing with a Haswell processor. This is a niche product, but there are still a number of competitors. The list includes the Dell Latitude 13 7350 and the Toshiba Portégé Z20t-B, for example. Microsoft's Surface Pro or the Surface Book could also be alternatives for some users, even though they are not specifically designed for business users.

Case & Connectivity

The tablet element is made entirely of black plastics and the lid is rubberized. There is not much to criticize in terms of the build quality, but the tablet could be more robust since you can twist it quite a lot. The supplied Power Keyboard is also made of sturdy plastic, but it is not a Folio keyboard. The top is silver-colored and the bottom is black. We cannot find any build quality issues with the keyboard, either. It could also be more robust as you can easily twist it. Both the tablet and the docking station have their own batteries. HP also offers an optional travel keyboard (around 220 Euros/~$239) as an alternative to the supplied unit. The travel unit is lighter and protects the tablet with a cover, but it does not have a battery. 

There is no shortage of ports on the Detachable. Among others, the tablet element offers a full-size USB 3.0 port. Note: The tablet ports cannot be used when the tablet is attached to the docking station. There are also two USB 3.0 ports on the keyboard dock as well as two video outputs. On the right side of the dock is an HP docking port, which can be used with the optional HP 2013 UltraSlim docking station, for instance.

The convertible comes with a preloaded version of Windows 8.1 Pro (64-bit), so you do not get the latest operating system. Windows attempts to download updates with a total size of 2.2 GB. We skipped this step and just upgraded to Windows 10, which was very simple. After the upgrade, we found a "Wacom Device" in the device manager without a driver, but the problem was easily solved. The necessary driver (Wacom Digitizer Pen Driver) is available in the driver section of HP’s website. Windows 10 is supported. Our review unit does not come with an input pen, but it is available for around 30 Euros (~$33).

Input Devices

The supplied keyboard dock is equipped with an illuminated chiclet keyboard. The illumination has two settings that can be selected via a function key. The flat and slightly roughened keys provide short travel and a well-defined pressure point. There is some amount of flex during typing, but it was not that big a deal. The 9.7 x 4.4 cm (~3.8 x 1.7 in) multi-touch touchpad provides sufficient space for gestures. The smooth surface provides good gliding capabilities. Below the pad are two separate mouse buttons with a short travel and clear pressure point.

Display

The Pro x2 612 is equipped with a 12.5-inch touchscreen with a native resolution of 1366x768 pixels. The screen provides a good contrast (863:1), but the luminance is too low (267 cd/m²) for a device that is used in different locations and under different lighting conditions. Positive: PWM flickering is not a problem for the display. The HP Detachable is also available with a Full HD screen.

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: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9365 (minimum: 43 - maximum: 142900) Hz was measured.

We can measure a DeltaE-deviation of 4.21 ex-works, so it just misses the target value (DeltaE smaller 3). We cannot see a blue cast.

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
36 ms ... rise ↗ and fall ↘ combined↗ 10 ms rise
↘ 26 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. » 92 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey
43 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 23 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. » 61 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (39.7 ms).

HP has equipped the detachable with an IPS panel that provides wide viewing angles. This means that you can see the display content from every position. You cannot use the device outdoors due to the low luminance and the glossy screen surface.

Performance

The HP Pro x2 612 G1 is a 12.5-inch business detachable. It provides sufficient performance for office and web applications. The device offers several business features such as TPM, biometric access protection and a docking port. Our review unit retails for around 1050 Euros (~$1140) and is therefore the least expensive configuration of the series. HP offers other configurations, including models with integrated LTE modem, for example.

Processor

The Pro x2 612 was launched in 2014 and is therefore not equipped with a modern Skylake processor. Instead, it uses a dual-core Intel Core i3-4012Y based on the Haswell generation. This is a very frugal chip with a TDP of just 11.5 watts. The CPU runs at a nominal clock of 1.5 GHz and there is no Turbo Boost. However, the CPU supports Hyperthreading (each core can execute two threads) and can utilize its maximum performance in our benchmarks, both on mains as well as battery power.

System Performance

The system runs smoothly and we did not experience any issues. The results in the PCMark benchmarks are good. This is not surprising because the device is equipped with an SSD as well as dual-channel memory. It is not possible to increase the performance even further.

GPU Performance

Intel's HD Graphics 4200 handles the graphics output. The GPU supports DirectX 11 and runs at clocks between 200 and 850 MHz. Thanks to the dual-channel memory configuration, the GPU can use its full potential and as a result, the 3DMark scores are slightly higher compared to other HD 4200 devices.

Gaming Performance

The Pro x2 612 is an office device and was not designed to handle games. You can still play some games with the device – with reduced settings and low resolutions. However, this only applies to games that do not have high hardware requirements. A modern game such as “Rise of the Tomb Raider” cannot be played at all. Many playable games can be found in the Windows Store under Casual Games.

Emissions & Energy

System Noise

The convertible uses one fan, which is usually deactivated while idling and therefore the device is usually silent in this case. The system noise increases to 37.5 dB(A) during the stress test – an acceptable result. Unfortunately, there is some annoying noise, because we can hear an electronic humming/whistling noise.

Temperature

Stress test
Stress test

The HP convertible executes our stress test (Prime95 and FurMark for at least one hour) in a similar manner on mains and battery power. The processor can always utilize its full performance (1.5 GHz) and the same applies to the graphics core (850 MHz). However, the latter occasionally fluctuates between 750 and 850 MHz during the test. The Pro x2 612 does not really get warm at all; only two measurement spots exceed 30 °C (~86 °F).

(±) The average temperature of the palmrest area of similar devices was 28.9 °C / 84 F (-0.9 °C / -1.6 F).

Speakers

The stereo speakers are at the lower edge of the tablet's back. They create a decent sound, but it lacks bass. Thanks to the preloaded DTS software, you can also adjust the sound based on your preferences. It is also possible to attach headphones or external speakers. There is one combo audio jack at the tablet and the keyboard dock each.

Power Consumption

The idle consumption of the convertible can reach up to 8.1 watts – an acceptable result. We can measure 27 watts during the stress test – CPU and GPU run at their maximum clocks. The nominal output of the power adaptor is rated at 45 watts.

Battery Runtime

We simulate typical web browsing with our realistic Wi-Fi Test. The profile "Balanced" is active and the display brightness is adjusted to around 150 cd/m². The Pro x2 612 manages a runtime of 7:37 h – a good result. The convertible is equipped with two batteries: One inside the tablet (29.3 Wh) and one in the keyboard dock (25 Wh).

Verdict

In review: HP Pro x2 612 G1. Test model courtesy of HP Germany.

The HP Pro x2 612 G1 is a business detachable with a 12.5-inch screen. The processor provides sufficient performance for common tasks. The device is usually quiet or even silent and does hardly get warm. A fast SSD ensures a snappy system. It could be replaced by a module with a higher capacity if necessary, because it is a standard M.2-SSD. You also get a good keyboard that meets the requirements of prolific writers. The whole package is rounded off by several business features such as TPM, fingerprint scanner and SmartCard reader. If you invest a few more Euros, you can also get the convertible with an integrated 3G/LTE modem. We think the display should be improved; it does provide a good contrast, but the luminance is too low. This, combined with the glossy display surface limit  the usage scenarios.

This is a special device for business users in need of both a tablet as well as a notebook, but do not want to carry around two devices.

An alternative for the HP convertible is obviously the MS Surface Pro, even though the comparison is rather misleading. For starters, the Surface Pro does not offer the numerous ports in the keyboard dock, and there is also no version with an integrated 3G/LTE modem. A real alternative for the HP Pro x2 612 G1 with much longer battery runtimes is the Toshiba Portégé Z20t-B, but it is also more expensive.

Andreas Osthoff - Senior Editor Business
I grew up with computers and modern consumer electronics. I am interested in the technology since I had my first computer, a Commodore C64, and started building my own PCs after that. My focus here at Notebookcheck is the business segment including mobile workstations, but I also like to test new mobile devices. It is always a great experience to review and compare new products. My free time is filled with a lot of sports, in the summer mainly on my bike.
