A 4K Laptop For $440: Chuwi LapBook Plus Review

What could go wrong? It's got the looks of a $1000 Ultrabook but with the performance of a $100 netbook. There's a good reason why you don't see many Intel Atom laptops with 4K UHD displays in the market; they are an imbalanced pairing.

The 15.6-inch Chuwi LapBook Plus is Chuwi's latest model in its lineup of visually appealing and yet super-cheap laptops. It follows on the footsteps of the smaller AeroBook and HeroBook in terms of chassis design and so many of our existing comments on Chuwi systems can apply here.

The LapBook Plus is most notable for its pairing of an Intel Atom E3950 CPU with a 4K UHD display for just $439 USD — not something you see everyday in the laptop world. Nonetheless, our benchmarks and experience with the model will show why it's not a very good idea to have such a weak processor power a very high resolution display on a Windows PC.

There are no major direct competitors in this space because the LapBook Plus is one of the only laptops with a 4K UHD display retailing for under $500 USD. However, plenty of laptops and tablets with very low power CPUs are available in this price range including the HP Pavilion 15, Acer Swift 3, HP x2, or Lenovo IdeaPad 110.

The official product page for the LapBook Plus can be found here.

Case

Like other Chuwi laptops, the LapBook Plus is an unabashed knockoff of Apple or, in this case, the 2018 MacBook Air. Colors and surfaces mimic the Apple equivalent even if the chassis itself is noticeably weaker and more flexible to the touch. The hinges in particular tend to creak and become more fragile when opened to their maximum angle. Other 15-inch Ultrabooks like the XPS 15 or Spectre x360 15 have stiffer and sounder bodies that are more reflective of their 4-digit price points. This may look like an Apple, but it definitely doesn't feel like one.

The LapBook Plus can afford to be very thin and lightweight because its very low-power CPU requires no active cooling. In fact, it's lighter than most 15.6-inch laptops with the notable exception of the LG Gram 15. Dimensions are very nearly identical to the Asus VivoBook S15.

Connectivity

While port positioning is excellent, port options are a mixed bag. The system utilizes the uncommon mini-HDMI port instead of a full-size HDMI and there is no USB Type-C. A proprietary AC adapter is required for charging whereas many other Ultrabooks have already moved on to universal USB Type-C charging.

SD Card Reader

Good luck trying to get that MicroSD card out
Good luck trying to get that MicroSD card out

Transfer rates from the integrated MicroSD card reader are slow at only about 16 MB/s. Moving 1 GB of images from our UHS-II test card to desktop takes 45 seconds compared to under 8 seconds on the XPS 15.

Perhaps the worst aspect of the spring-loaded card reader slot is that a fully inserted MicroSD card sits inside slot to be very difficult to eject without a long fingernail or sharp pen.

Communication

An integrated Intel 3165 module provides WLAN and Bluetooth 4.2. Transfer rates are limited to a theoretical 433 Mbps compared to 1.73 Gbps with the Intel 9560 commonly found on newer Ultrabooks. We experienced a couple of connectivity issues during the start of testing, but they never propped up again thereafter.

Maintenance

The bottom panel comes off easily with just a Philips screwdriver so long as you are careful around the sharp edges. Nearly all components are soldered and not upgradeable including the WLAN and RAM.

Accessories and Warranty

There are no extras in the box other than the AC adapter. While there is a one-year manufacturer warranty, the overseas shipping and handling will more than likely be a hassle for most users.

Input Devices

Keyboard

The backlit keyboard is easily one of the best aspects of the LapBook Plus. It offers firm feedback, deep travel for an Ultrabook, and low-moderate clatter not unlike the keyboard on the HP Spectre x360 15. We especially applaud the full-size NumPad and Arrow keys as these are usually much smaller or narrower than the main QWERTY keys on most other laptops like the Asus TUF FX505DT.

Touchpad

The large clickpad (13 x 9 cm) is unfortunately defective on our test unit. The cursor would frequently pause or jump for seemingly no reason to be essentially unusable. It's a shame because gliding is otherwise quite smooth when moving at medium-fast speeds on the slightly roughened surface.

Clicking on the firm clickpad produces a shallow and satisfying audible click. The main issue is that it takes quite a bit of effort to input a click and so it can become tiring very quickly when browsing or dragging and dropping.

Display

It's clear that Chuwi invested a lot on the 4K UHD display relative to the rest of the laptop. The high quality BOE NV156QUM-N51 IPS panel here can also be found on the Lenovo Yoga 730-15IKB that retails for four times the price. The visual experience between these two laptops are therefore very similar including the high contrast ratio of about 1000:1, average response times, and the respectable color coverage. The backlight in particular is brighter than any sub $500 laptop we've seen in this size category.

Pulse-width modulation is present on all brightness levels up to 99 percent which might impact users sensitive to onscreen flickering. The glossy overlay eliminates any graininess issues common on matte displays for crisp texts and images.

Further measurements with an X-Rite colorimeter reveal just average grayscale and an overly cool color temperature out of the box. Our calibration attempt improves both aspects for a more accurate display especially for colors at lower saturation levels.

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
25.2 ms ... rise ↗ and fall ↘ combined↗ 14 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. » 44 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.8 ms).
       Response Time 50% Grey to 80% Grey
40 ms ... rise ↗ and fall ↘ combined↗ 21.2 ms rise
↘ 18.8 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. » 45 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (39.5 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 961.5 Hz ≤ 99 % brightness setting

The display backlight flickers at 961.5 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 961.5 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9331 (minimum: 43 - maximum: 142900) Hz was measured.

Outdoor visibility is decent when working under shade. Otherwise, anything brighter will accentuate glare and wash out colors. Be prepared to constantly adjust the display angle because of the glossy screen. Viewing angles are wide with some noticeable color and contrast degradation only if viewing from abnormally extreme angles.

Performance

5 minutes of LatencyMon
5 minutes of LatencyMon

The quad-core Intel Apollo Lake Atom x7-E3950 is the only processor option available. This rare CPU is comparable in performance to the more common Cherry Trail Atom x5-Z8350 as found on cheap tablets and netbooks like the Asus Transformer Book or Lenovo IdeaPad Miix 310. Performance is significantly slower than anything from the Core ix series since Atom CPUs can be passively cooled.

System RAM is fixed at 8 GB DDR4. LatencyMon shows issues handling real-time audio even when the wireless is disabled.

Processor

CPU performance from the quad-core Atom x7-E3950 is abysmally slow. Multi-thread performance is about 30 percent faster than the Atom x5-Z8350 in the Chuwi Hi10 Air, but overall performance is still some of the slowest for any modern laptop. Alternatives with Core i3, Celeron N4100, or even Core m are able to perform faster than what is offered here on the LapBook Plus.

See our dedicated page on the Atom x7-E3950 for more technical information and benchmarks.

System Performance

PCMark results are consistently ahead of the HP x2 with the Atom x5-Z8350 but still far below the average multimedia laptop. The extremely low scores translate to slow launch times and even annoying delays in typing.

Storage Devices

An uncommon Kimtigo 256 GB M.2 SSD can be found on our test unit. While sequential read and write rates are standard for a SATA III SSD, its read and write rates of smaller 4K blocks are slower than usual. Thus, workloads involving large amounts of smaller files instead of larger ones will take much longer to complete including Windows Update software installations.

See our table of HDDs and SSDs for more benchmark comparisons.

GPU Performance

Integrated Atom GPUs are more about streaming than gaming. We're able to play 4K UHD videos on YouTube at 60 FPS at a CPU utilization of around 50 to 60 percent. The catch is that everything else will slow to a crawl and so even the simplest of user inputs like fast forwarding, pausing, exiting, or resuming will have very long delays.

Temperature

Surface temperatures are cool around the palm rests, clickpad, and most of the keyboard. The hot spots are concentrated around the corner nearest the passively cooled CPU where temperatures can reach over 50 C when subjected to prolonged extreme processing stress.

Stress Test

We stress the laptop to identify for any potential throttling or stability issues. When running Prime95, CPU clock rates jump to 1.9 GHz for the first few seconds before falling and stabilizing at 1.6 GHz. Core temperature eventually plateaus at about 81 C when under 100 percent utilization.

Running on batteries will not impact performance. 3DMark 11 results are nearly the same when running on batteries or on mains.

Speakers

The stereo speakers are weak in volume with poor bass reproduction. Perhaps the latter is to be expected from a sub $500 laptop, but the low volume impacts the overall multimedia experience and it can make conference calls difficult to hear.

Energy Management

Power Consumption

The system draws 6 W to 11 W when idling on desktop depending on the brightness level and power profile. While efficient, it's not as efficient as we were anticipating from an Atom-powered laptop likely due to the brighter than average display and more demanding 4K UHD resolution. Running 3DMark 06 draws 21 W to be similar to a Core i5-powered Surface Pro 6.

The very small (~10 x 4.5 x 3 cm) 36 W AC adapter is more than enough to power and recharge the system simultaneously no matter the onscreen load.

Battery Life

Battery life is short at just 3.5 hours of real-world WLAN use when set to 150 nits brightness (setting 4/10). In comparison, the Asus VivoBook S15 manages almost 6.5 hours when subjected to the same WLAN conditions. The very small 36 Wh internal battery is at least partly responsible for the wide discrepancy.

Recharging from empty to full capacity takes the full 2 hours.

Verdict

In review: Chuwi LapBook Plus. Test model provided by Chuwi
In review: Chuwi LapBook Plus. Test model provided by Chuwi

As slim and sexy as it may appear, performance is just too slow to recommend for anything more than a simple print server or emailing station. Even the simplest of actions like clicking and typing have noticeable delays to make the LapBook Plus a poor choice for multimedia, streaming, or browsing purposes.

To Chuwi's credit, the keyboard is actually quite good compared to other Ultrabooks and the 4K UHD display is unmatched at this price range. Unfortunately, these respectable qualities are of no practical use since they've been dragged down by one the slowest processors you can get on any laptop coming out this year.

A good-looking laptop trapped in Intel Atom purgatory. The very slow processor drags down what could have been a decent inexpensive Ultrabook. Users would be better off with a last generation Core i3 laptop for tangibly faster and more reliable performance.

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.
