Chuwi UBook Pro Tablet Review: The Microsoft Surface Pro Clone

The Clone Wars. The UBook Pro offers high-end looks with low-end performance for a mid-range price. If you can get past the slow Core m3 processor, then you'll find the super-bright 12.3-inch display and three USB ports quite useful when compared to the dimmer and pricier Surface Pro.

After offering one of the cheapest 15.6-inch 4K UHD laptops available, Chuwi is now aiming for Microsoft Surface Pro users with its own Surface Pro clone. The UBook Pro sports the same 12.3-inch screen size as the Surface Pro along with a detachable keyboard cover and active stylus pen all for about $500 USD.

Of course, looks aren't everything and the UBook Pro has plenty of cut corners once you dig deeper into the device. The tablet 2-in-1 competes directly with other Windows tablets including the Lenovo Miix 520, HP Elite X2, Dell Latitude 5290 2-in-1, and the Microsoft Surface Go and Surface Pro series.

Check out the official UBook Pro Indiegogo page here to learn more about the system.

Case

We had low expectations going in since most Chuwi laptops thus far have been flexible and prone to damage. Thankfully, the UBook Pro bucks this trend by being almost as firm as the Surface Pro, Elite x2, or Lenovo Miix. The keyword here is "almost" as we can still observe some minor twisting, creaking, and depressions when attempting to bend the corners or warp the glass screen. First impressions on the metal chassis, U-shaped bracket, and overall build quality are still excellent nonetheless.

One annoying aspect of the design relates to the U-shaped hinge. When at a small enough angle, the hinge will automatically close shut which can make fine-tuning the display angle somewhat of a hassle. 

Dimensions and weight are, unsurprisingly, nearly 1:1 with the Surface Pro 6. It's ever-so-slightly larger and heavier for users keeping track of decimal places. If you've handled a Surface Pro before, then you'll know what to expect from the UBook Pro in terms of portability.

Connectivity

Port options are pretty good for an inexpensive Windows tablet. The two USB Type-A ports and single USB Type-C port are already more than what the Surface Pro series or the iPad series have to offer. An uncommon Micro-HDMI port is present which most users will likely need an adapter for.

USB Type-C PD is supported meaning that you can recharge the UBook Pro with a third-party USB Type-C AC adapter.

SD Card Reader

Transfer rates from the spring-loaded MicroSD reader are decent at about 80 MB/s. Moving 1 GB worth of images from our UHS-II card to desktop takes roughly 15 seconds. Ejecting the MicroSD card can be difficult and tricky without accidentally shooting the card across the room.

Communication

The Intel 3165 module offers 1x1 connectivity for up to 433 MB/s transfer rates and integrated Bluetooth 4.2. It's a rather old WLAN module by today's standards, but the UBook Pro is relatively inexpensive, after all. We experienced no connectivity issues during our time with the test unit.

Accessories and Warranty

The retail box includes an active stylus pen, AAAA battery, and a detachable keyboard. 

The standard one-year limited warranty applies. Nonetheless, claiming said warranty may prove difficult as Chuwi will require owners to ship their defective units back to Asia.

Input Devices

Keyboard

Typing on the detachable keyboard is less than optimal. The keyboard deck itself is not at all firm meaning that every key press will teeter or depress the entire keyboard. Feedback is therefore spongy and weak even by Ultrabook standards. We recommend a proper USB keyboard for longer typing sessions.

Touchpad

The small clickpad (~9.5 x 5.3 cm), which is not Precision compatible, works reliably enough for basic cursor control. However, multi-touch inputs, drag and drop, and mouse clicks are hit or miss and oftentimes frustrating.

Display

Chuwi products tend to carry above-average displays and the UBook Pro is no exception. The 12.3-inch 3:2 1920 x 1280 BOE TV123WAM IPS panel here can be found on no other laptop or tablet in our database as of this writing and yet it is able to rival the LG Philips LP123WQ112604 panel on the Surface Pro 6. Our table below shows respectable color coverage, contrast ratio, and response times for a Windows tablet.

The most notable aspect of the screen is its very bright backlight of up to 868 nits to be significantly brighter than most other Windows tablets and Ultrabooks where the 400 to 500 nits range is the norm.

While color space is respectable, further measurements with an X-Rite colorimeter reveal an inaccurate display out of the box. Color temperature is far too cool for a bluish hue. Calibrating the display ourselves improves average DeltaE values significantly. We recommend calibrating the display or applying our calibrated profile above to get the most out of the UBook Pro.

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
26.8 ms ... rise ↗ and fall ↘ combined↗ 15.6 ms rise
↘ 11.2 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 0.8 (minimum) to 240 (maximum) ms. » 54 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.5 ms).
       Response Time 50% Grey to 80% Grey
30.8 ms ... rise ↗ and fall ↘ combined↗ 14.8 ms rise

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 21 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (39 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 not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17878 (minimum: 5 - maximum: 2500000) Hz was measured.

Outdoor visibility is better than expected because of the super-bright backlight. Nonetheless, glare will still be present due to the glossy overlay. Viewing angles are wide with changes in contrast and colors appearing only if viewing from extreme angles.

Performance

Unlike most Ultrabooks and Windows tablets in the market, the UBook Pro uses a passively-cooled 4.5 W Core m3-8100Y CPU instead of the faster 15 W Core U-series. This is the most noticeable disadvantage to the Chuwi as launching or switching between multiple applications is slower and more sluggish. Meanwhile, its integrated UHD graphics 615 is unfit for anything more than word processing or 4K UHD video playback. There are no secondary CPU, GPU, RAM, or display resolution options available other than what we have here.

LatencyMon shows no DPC latency issues.

Processor

CineBench R15
CineBench R15

CPU performance is comparable to the Pentium Gold 4415Y found inside the Surface Go in regards to multi-threaded performance while being 40 percent faster in single-threaded performance according to CineBench R15. Even so, overall performance is slower than even the Celeron N4100 and not all that much better than an Atom x7-E3950.

See our dedicated page on the Core m3-8100Y for more technical information and benchmarks.

System Performance

PCMark 10 reveals the weakest link of the UBook Pro: the integrated GPU. Its Digital Content Creation score is 50 percent lower than the already slow UHD Graphics 620. This is not the system to use for even the lightest of video editing or image editing. We otherwise experienced no software issues during our time with the unit.

Storage Devices

The 256 GB Netac SSD appears to operate at speeds slower than most SATA III SSDs likely to keep costs low. AS SSD reports average sequential read and write rates of only 247 MB/s and 147 MB/s, respectively, compared to ~550 MB/s on inexpensive SATA III SSDs. Pricier tablets tend to ship with even faster NVMe drives.

GPU Performance

The UHD Graphics 615 is designed for light office tasks and video playback as anything more demanding will chug the system. Attempting to multi-task during 4K playback, for example, will cause frames to drop like no tomorrow.

See our dedicated page on the UHD Graphics 615 for more technical information and benchmarks.

Stress Test

We stress the system with synthetic loads to identify for any potential throttling issues. When running Prime95, the CPU will boost to 2.7 GHz for the first few seconds until core temperature hits 80 C. Thereafter, clock rates drop and stabilize at 1.4 GHz in order to maintain a cooler core temperature of 62 C.

Running on battery power will not impact performance very much. A Cloud Gate test on batteries returns Physics and Graphics scores of 1876 and 4364 points, respectively, compared to 1941 and 4521 points when on mains.

Speakers

As with most tablets, the integrated speakers on the UBook Pro are not very loud and have poor bass reproduction. Roll-off begins at 1k Hz compared to 250 Hz or 500 Hz on most Ultrabooks. Earphones are recommended for any sort of multimedia playback.

Energy Management

Power Consumption

Idling on desktop demands anywhere between 5.4 W and 12.5 W depending on the brightness setting. Since the display is so bright when set to maximum, the Chuwi can be more power-hungry than many of its competitors during low processing loads.

We're able to record a maximum draw of 25.9 W when the CPU is at 100 percent utilization from the small 24 W AC adapter (~8 x 4.5 x 2.5 cm). This high of a consumption is only temporary as shown by our graphs below and so the tablet can still recharge simultaneously when under high loads. It's too bad that the UBook Pro ships with a proprietary AC adapter instead of the more universal USB Type-C adapter.

Power consumption is unusually high when shut off at 1.8 W.

Minimum brightness from 0s to 10s and maximum brightness from 10s and onward. Full brightness drains an additional 6 W

Battery Life

Battery capacity is smaller than on the Surface Pro 6 (38 Wh vs. 45 Wh). Expect about 5.5 hours of real-world WLAN use when the display is set to 150 nits (or approximately 15 percent) to be comparable to the more powerful Lenovo Miix 520.

Recharging with the included AC adapter is very slow. A fully drained battery takes about 3 hours to recharge compared to just half that on most Ultrabooks.

Verdict

In review: Chuwi UBook Pro. Test unit provided by Chuwi
In review: Chuwi UBook Pro. Test unit provided by Chuwi

The UBook Pro outclasses the Surface Pro series in two key areas: display brightness and port options. It's both easier to see outdoors and less reliant on clunky external docking stations since it integrates more ports than any Surface tablet.

Look past these two advantages and the UBook Pro becomes a mediocre Windows tablet. Its Core m3 CPU is noticeably slower than the Core i5 or i7 SKUs of the Surface Pro and its detachable keyboard is inferior to Microsoft's version in both quality and key feedback. You'd be better off with a Surface if you intend to do a lot of typing. For very light web browsing and word processing, however, the UBook Pro will prove sufficient especially at this price range.

A Windows tablet with both a brighter display and more integrated ports than the Surface Pro for hundreds of dollars less. The big drawbacks are performance and keyboard feedback which shouldn't impact light browsing or the occasional emailing.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
