LG Gram 14Z90P in review: Superior endurance and finally more performance

No excess gram(s). The LG Gram is known as an endurance runner among laptops. The new LG Gram 14Z90P 14-inch model weighs less than a kilogram but once again convinces with extremely long battery life. Our review will reveal other compelling features of the subnotebook.
Marcus Schwarten, 👁 Sebastian Jentsch (translated by Stephanie Chamberlain), 🇩🇪 🇳🇱 ...

With the Gram 14Z90P-G.AA79G, LG once again launches an updated version for the title of the most enduring subnotebook on the market in 2021. In comparison to the LG Gram 14Z90N predecessor, the new generation is equipped with the current i7-1165G7 Tiger Lake CPU including the Iris Xe G7 96EUs integrated GPU. In addition, there's 16 GB of RAM and a 14-inch IPS panel with a resolution of 1920x1200 pixels.

Not only will we take a look in our review of the new LG Gram 14Z90P at how well the updated hardware performs and what advantages it offers. Naturally, when it comes to a battery prodigy like this one, we will also focus on the impact of the model update on battery life. How does the new generation compare to the predecessor and other lightweights like the Lenovo Yoga Slim 7i Carbon 13 ITL, the Asus ExpertBook B9 B9400CE-KC0166R, or the Huawei MateBook X?

Case: Light and elegant as usual

Compared to last year's model, little has changed in terms of looks. The 2021 LG Gram 14 once again features a sophisticated and minimalistic design. Not only does the full-metal case made of a magnesium alloy make a high-quality impression and is excellently crafted, but it's also particularly robust according to the manufacturer as the compliance with the MIL-STD-810G military standard shows. Nevertheless, we didn't subject the device to a drop test.

The hinge is quite stiff. It holds the display quite firmly in its place and position, and it only wobbles slightly when moved. However, opening the device with only one hand can be a bit of a challenge, and the low weight doesn't help for once in this regard. 

Besides its long battery life, the LG Gram is especially known for its low weight. This is also proven by the new LG Gram 14Z90P: Once again, it weighs less than one kilogram. Compared to last year's model, the LG Gram 14Z90N, it's slightly lighter as well as a bit narrower and thinner.

The device holds its own in the comparison field. It can't keep up with the ultra-thin Huawei MateBook X, but it offers much more performance and endurance in return. Users looking for a mobile companion that is light and compact won't go wrong with the 2021 LG Gram 14 once again.

Connectivity: Laptop with all the necessary ports

The LG Gram 14Z90P offers all the ports that are needed in everyday use. Besides USB-C/Thunderbolt 4, there's also USB-A. In addition, two external 4K monitors or an 8K display can be connected via HDMI and DisplayPort (via USB-C). All ports are distributed along the left and right sides of the case and provide sufficient distance between them for unobstructed use.

SD card reader

The microSD card reader to the right reaches average speeds with a 64 GB Toshiba Exceria Pro UHS-II SDXC reference memory card. This is sufficient to copy a few photos from a memory card. However, you should be prepared for some waiting time for larger amounts of data. We can't make a comparison with the direct competitors at this point, since they lack the corresponding slot.

Communication

The integrated Intel Wi-Fi 6 AX201 WLAN module is used in all comparison models. However, it delivers the worst performance in the LG Gram 14Z90P reviewed here. It's clearly behind most of the comparison models. Only Huawei's fanless MateBook X performs comparably poorly.

Webcam

The webcam that is integrated into the upper display bezel has a resolution of 720p and leaves a solid impression in the test. Color deviations are sometimes a bit higher than in the comparison models. Contrast and sharpness are okay, so the webcam is good enough for video calls and the like.

Security

In addition to a fingerprint sensor that is integrated into the device's power button on the keyboard's upper right, the laptop can also be secured with a Kensington lock.

Accessories

Apart from the 65-watt comfortably compact power adapter, LG doesn't include any other accessories with the Gram 14Z90P.

Maintenance

Self-conducted maintenance procedures are difficult to perform. All the screws on the underside are covered and consequently not readily accessible.

Warranty

LG grants customers the usual manufacturer warranty of 24 months out of the box. Optional warranty extensions aren't offered by the manufacturer.

Input devices: Improved keyboard with more travel

Keyboard

Compared to the predecessor, LG has increased the size of the keys and the key travel from 1.5 to 1.65 mm. This results in a keyboard that is comfortable to type on, and its keys have a decent travel and pressure point considering the thickness of the device. The noise development during typing is kept within limits.

LG now uses a uniform white color for the labels of the various additional functions, which were colored in the predecessor. This might make it less easy to find a specific function key, but it looks much more elegant. In addition, the backlight that illuminates the entire keyboard is helpful and can be adjusted in two stages. For this, the LG Control Center has to be accessed via "FN + F1". Unfortunately, the still very small arrow keys haven't been made bigger. But they're no longer so mushy.

Touchpad

The centered touchpad measures approximately 11 x 7 cm. It's minimally embedded in the case and has a very smooth surface. Furthermore, the mouse cursor largely responds without any issues. We couldn't find the "jamming" of the predecessor in the new model. The noise level produced by the left and right clicks is acceptable. We've experienced louder but also quieter noise levels.

Display: Unfortunately, strongly reflective

LG has installed a 14-inch IPS LCD panel with a white LED backlight in the Gram 14Z90P. The display has an aspect ratio of 16:10 with a resolution of 1920x1200 pixels. Subjectively, the display is crisp and sharp, and it doesn't give any cause for complaint.

The average brightness is a good 300 cd/m². That is solid, but especially in outdoor use, it quickly becomes the device's doom. Particularly since the display is glossy and consequently highly reflective. The brightness distribution is quite even, and screen bleeding is almost non-existent.

Compared to the predecessor, the panel in the 2021 model performs much better. LG was partly able to considerably improve many important aspects, such as contrast, brightness, and black value.

* ... smaller is better

In contrast, color reproduction is not as good. It exhibits larger deviations out of the box that can't be improved that much even with a calibration.

On the other hand, a positive point is that color-space coverage has been significantly increased. The new LG 14Z90P covers 100% of sRGB and 76% of AdobeRGB.

Overall, the display only ranks in the midfield compared to the other models, which is mainly due to the color reproduction.

The reflective display is a hindrance for the device outdoors. What is already annoying indoors with unfavorably positioned light sources, such as windows, becomes a nightmare outdoors. As the photo below shows, a cloudy sky or even the user sitting in front of the device result in very strong reflections. Therefore, the LG Gram 14Z90P is truly not the ideal companion for outdoors, which is a pity due to the low weight. On the other hand, the IPS panel's usual high viewing angle stability is excellent.

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
23 ms ... rise ↗ and fall ↘ combined↗ 9 ms rise
↘ 14 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 35 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24 ms).
       Response Time 50% Grey to 80% Grey
45 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 25 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 636 (maximum) ms. » 69 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (38.1 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: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 14793 (minimum: 5 - maximum: 2500000) Hz was measured.

Performance: LG Gram 14 with Tiger Lake performance upgrade

Compared to last year's model, the LG Gram 14Z90P has made the leap to the 11th generation of Intel CPUs. Instead of the Ice Lake i7-1065G7, the new Gram is now equipped with the Tiger Lake i7-1165G7. This is accompanied by an onboard graphics upgrade from the Iris Plus Graphics G7 64EUs to the Iris Xe G7 96EUs.

We will describe how these improvements affect performance in the following sections. We expect a performance boost, since the new CPU offers significantly more than the Ice Lake generation.

Alternatively, the Gram 14Z90P-G.AP55G is available in a Business Edition with the i5-1135G7 and a slightly different configuration for 200 Euros (~$245) less.

Processor

It's sufficiently known that Intel managed a significant performance leap with the jump from Ice Lake to Tiger Lake. This is proven by the i7-1165G7 in the LG Gram 14Z90P. The new model is considerably ahead of the predecessor with its i7-1065G7 in all benchmarks.

Compared to the other reference models, the CPU with 18 watts (PL1) to 52 watts (PL2) is a solid competitor, but it's often close to the bottom in the duel against the identically equipped Lenovo Yoga Slim 7i Carbon 13 ITL ITL and the Asus ExpertBook B9. The LG subnotebook can't quite keep up with the processor's average rate either. A performance drop on battery power is hardly noticeable.

DPC latencies

The LG Gram 14Z90P shows solid latencies in the test. Although the measurement is always only a snapshot, the determined value is clearly below that of the predecessor. However, the test candidate can't entirely keep up with the other comparison subnotebooks. This could point to problems with real-time audio, but these weren't observed in the test period.

Graphics card

While the new CPU brings a good gain in performance compared to the predecessor, graphics performance makes a real leap. This shows how much faster and better the new Iris Xe G7 96EUs GPU is compared to the predecessor Iris Plus Graphics G7 64EUs. The reason for this is that all 96 EUs operate at a clock rate of 400 to 1,300 MHz.

In the graphics benchmarks, the LG Gram 14Z90P pulverizes the performance of its predecessor, the LG Gram 14Z90N. As a result, there is a clear performance increase compared to the predecessor. The device also stands out in comparison to the other subnotebooks. It can easily keep up with the comparably equipped Lenovo Yoga Slim 7i Carbon 13 ITL and Asus ExpertBook B9 B9400CE-KC0166R alternatives, and it often even achieves the best score. The current Gram 14 is also clearly above the average of all devices with the same GPU. Not only does LG focus on long battery life, but it also pushes the hardware to the limit when necessary. In addition, benchmark performance is hardly lower on battery power (about 5%).

Gaming performance

Despite having more graphics power, the LG Gram 14Z90P is certainly still not a gaming machine in the end. However, it can definitely be used for the occasional game thanks to the up-to-date hardware. The Witcher 3 ran well on medium graphics settings in our test, but other titles were only playable on the lowest settings at times.

Compared to the other models, the current LG Gram 14 performs well. It can outperform the rest of the devices as well as the graphics solution's average rate. In short: The lightweight is suitable for the occasional gaming session. However, you shouldn't have high expectations here.

Emissions: Runs pleasantly cool

Noise emissions

The LG Gram 14Z90P not only runs for a long time, but it also does so pleasantly quietly. It only just surpasses the limit of 30 dB(A) even under maximum load. Therefore, the laptop's noise level always stays pleasantly in the background, it's never intrusive, and it's barely audible at 26 dB(A) in idle usage.

A slight coil whine can be heard in our test device when listening very closely. At a normal sitting distance, however, this is only minimally audible in completely quiet environments.
