Panasonic Toughbook CF-33 (i5-7200U, QHD) Convertible Review

Robust. Panasonic's Toughbook is well-protected against dust, liquids, and falls. In addition to a robust case, the 12-inch detachable offers powerful hardware and many connections. The battery life is good.

For the original German review, see here.

With the Toughbook CF-33, Panasonic is delivering a robust 12-inch detachable, which is meant for use in rough surroundings. The computer is driven by a Kaby Lake processor, but companies that need a Windows-7 system can also order it with a Skylake CPU. The competitors include devices such as the Dell Latitude 14 7414 Rugged Extreme, the Dell Latitude 14 Rugged 5414 and the Bullman Dirtbook S12 Touch.

Case and Connectivity

The case of the Toughbook is made of plastic and metal. Panasonic uses black and silver colors here. It should not be surprising that the robust case does not offer any reason for complaint in terms of its workmanship and stability. Panasonic has not build-in only one, but two batteries (22 Wh and 3 cells each) which are both in the tablet section. The batteries can be replaced while the device is running, with one LED telling you which battery should be replaced. There is no battery in the keyboard dock, and you cannot insert one either.

There is no lack of connections. However, the potential buyers are not limited to Panasonic's selection of connections. Some slots can also be selected optionally, such as a SmartCard reader. The slots are protected from dust and moisture by lockable flaps.

The device has two storage card readers: one microSD reader in the tablet section and one SD reader in the keyboard dock. The latter is very slow. When copying large data blocks it achieves a maximum transfer rate of 29.1 MB/s, and 250 JPG files (about 5 MB each) are transferred with a speed of 27.5 MB/s. We are testing the storage card readers using a reference card, the Toshiba Exceria Pro SDXC 64 GB UHS-II. The competitors from Dell prove that significantly higher speeds are possible.

The WLAN module in the Toughbook has an Intel chip (Dual Band Wireless-AC 8265), which in addition to the 802.11a/b/g/n WLAN standards also supports the fast ac standard. The transfer speeds that we measured under optimal conditions (no other WLAN devices in close proximity and close distance between notebook and server PC) turned out below average. The Intel chip remains significantly short of its capabilities. Its transfer rates can be three times as fast.

Input Devices

Panasonic has equipped the device with a chiclet keyboard. The flat, roughened keys have a medium stroke and a clear pressure point. The key resistance could have been a bit crisper for our tastes. The keyboard does not bend while typing. Overall, Panasonic delivers a decent keyboard here that should be able to handle the demands put on it. We are missing a keyboard backlight. However, it is available optionally. 

The multitouch-capable touchpad has a footprint of about 7.9 x 4 cm (~3.1 x 1.6 in). The smooth surface allows the fingers to slide easily. Below the pad are two separate mouse keys, which offer a short stroke and a clear pressure point.

The touchscreen display did not give us any problems. It reacts promptly to input and supports 10 touch-points. The touchscreen can be operated with your fingers (this also works when wearing gloves) as well as the included input pen.

The reflective 12-inch touchscreen display of the Toughbook has a native resolution of 2160x1440 pixels. Panasonic uses a model in the 3:2 format here. The brightness (571 cd/m2) and contrast (5.191:1) are excellent. Unfortunately, the display shows PWM flickering at a frequency of 685 Hz. However, this high value should not lead to headaches or eye problems even for sensitive people.

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 685 Hz

The display backlight flickers at 685 Hz (worst case, e.g., utilizing PWM) .

The frequency of 685 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17933 (minimum: 5 - maximum: 3846000) Hz was measured.

The color reproduction is uninspiring. In the state of delivery, we are measuring a DeltaE-2000 color deviation of 22.7, with the target being a value smaller than 3. The display does not suffer from a blue tint.

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
29 ms ... rise ↗ and fall ↘ combined↗ 11 ms rise
↘ 18 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. » 73 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.5 ms).
       Response Time 50% Grey to 80% Grey
30 ms ... rise ↗ and fall ↘ combined↗ 11 ms rise

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 34 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (33.8 ms).

Panasonic has equipped the Toughbook with an IPS panel with stable viewing angles. Thus the display can be read from any position. The device can also be used outdoors in the sunlight.

Performance

With the Toughbook CF-33, Panasonic is offering a robust 12-inch detachable, which is meant for use in challenging environments. The price depends on the level of equipment. Our test unit costs between 4000 and 4500 Euros (~$3600 together with the keyboard dock in the US).

Processor

The Toughbook is driven by an Intel Core i5-7300U (Kaby Lake) two-core processor. This is a mid-range ULV model, which offers more than enough computing power for the intended usage environments of the Toughbook. The processor operates at a basic clock speed of 2.6 GHz, which you can increase via Turbo up to 3.5 GHz (both cores). The full Turbo speed is only available in single-thread applications. The multi-thread tests we performed were only running at full speed for a short time, before the CPU was throttled to 3.1 - 3.2 GHz. The behavior is identical in mains and in battery operation.

We test whether the Turbo can also be used constantly, by running the multi-thread test of Cinebench R15 in a constant loop for about 30 minutes. From the first to the second run, the result drops from 335 to 326 points and then stays at that level. So the CPU operates constantly at 3.1 to 3.2 GHz, and you cannot speak about a performance drop here.

System Performance

The system runs smoothly, and there were no problems. The powerful processor and the fast SSD are paying off here. The very good results of the Toughbook in the PC Mark benchmarks are confirming more than enough computing power for applications from the office and internet areas. An increase of the performance is not possible, and Panasonic has already done all that is possible.

Graphics Card

The Intel HD Graphics 620 graphics core supports DirectX 12 and runs at speeds of up to 1100 MHz. The results in the 3D Mark benchmarks are at a standard level for this GPU. It is positively noticeable here that the storage is running in dual-channel mode, using the graphics core to its full potential and causing it to deliver more performance.

Gaming Performance

The CPU-GPU combination of the Toughbook brings some games smoothly to the screen - in low resolutions and low quality settings. This goes primarily for games that do not put too many demands on the hardware. The working memory running in dual-channel mode has a positive effect on the frame rates, which turn out higher than in comparable devices whose memory runs in single-channel mode.

Emissions and Power

Noise Emissions

During idle and low loads, the fan often does not run, and the device operates silently. Even when the fan is running at low speeds, it can only be really heard in very quiet surroundings. Under full load, the noise development remains within limits. During the stress test, we registered a noise level of 36.6 dB(A). The device does not produce any other noises.

Frequency comparison (Checkboxes selectable!)

Power Consumption

While idling, the Toughbook appears very energy efficient. We were measuring a maximum use of only 5.15 watts. During the stress test, the value increased only up to 29 watts, since the CPU was throttled a lot. The included power supply is rated at 110 watts.

Battery Life

With a script, our practically relevant WLAN test simulates the load when loading websites. The "balanced" power profile is active, the display brightness is about 150 cd/m², and the power saving functions are turned off. The Toughbook achieved a runtime of 7:55 h, which is a good value. If you compare the battery life with its capacity, the Toughbook offers significantly more runtime per Wh than the competitors from Dell.

But this is not the full extent of it yet. Panasonic optionally offers larger batteries, which have almost exactly twice the capacity. While these batteries would stick out from the tablet segment, you would still be able to insert the tablet into the keyboard dock.

Panasonic uses two batteries which can be replaced on the fly.

Verdict

The Panasonic Toughbook CF-33, provided by Panasonic Germany
The Panasonic Toughbook CF-33, provided by Panasonic Germany

With the Toughbook CF-33, Panasonic offers a 12-inch detachable for extreme situations. The robust case protects the equipment from dust, moisture, and drops. Nonetheless, the device brings a relatively low weight to the scale.

The built-in Core i5 processor offers more than enough computing power for all the usual applications. Mostly the device runs quietly and hardly warms up. A Solid State Disk ensures a fast system.

The Panasonic Toughbook CF-33 is well-equipped for its intended usage.

The keyboard left a decent impression. However, we are missing a backlight, which is optionally available though. The device offers a good battery life, which can even be increased further with optionally available large-capacity batteries. The bright, high-contrast touchscreen display has stable viewing angles and left a good impression throughout. It can be operated with the fingers as well as with the included input pen.
