LG Gram Pro 16 ultralight laptop with Nvidia GeForce chip review - Bold minimalism
We have already thoroughly tested the LG Gram Pro as a convertible. As a conventional laptop, however, the LG Gram Pro may find itself at home in a different performance class. In addition to the Intel Core Ultra 7 155H, the device is equipped with an Nvidia GeForce RTX 3050. We last tested an LG Gram with a dGPU in 2022. However, due to the relatively low TDP values of its processor and GPU, this Gram 17 didn't totally impress us. Taking a look at the LG Gram Pro 2-in-1, on the other hand, we recently noticed that the manufacturer has significantly improved the laptops' performance. We will try to clarify the extent to which this affects our test device during this review. The RTX 3050 inside this laptop is a component which was launched almost four years ago. We sporadically noticed that the Arc iGPU with 128 EUs may offer slightly more performance.
The LG Gram Pro 16 isn't the only lightweight and slim laptop to feature a dGPU. The Samsung Galaxy Book4 Ultra, Asus VivoBook Pro 16, Lenovo Yoga Pro 9 and the HP Spectre x360 16 all have one, too. In turn, the LG device is by far the lightest in the comparison field. This is because it uses a case made from ultralight magnesium and the rest of the laptop's materials have been kept as minimal as possible. Let's find out what impact this had on our test device's performance.

Case
In principle, the LG Gram Pro 16 doesn't look all too different compared to the LG Gram Pro 2-in-1 which we recently tested. It just doesn't feature the 360° hinges and the glass panel in front of the screen. Apart from this, both of the 16-inch devices barely look any different visually. Only upon closer inspection do you notice that certain corners aren't quite as sharp on one device as they are on the other. Ultimately, you can speak of one coherent design. You can also get the LG Gram Pro as a 17-inch model, but without an OLED display. This version uses the same high-quality IPS panel as the LG Gram 17.
When it comes to stability, the Gram Pro 16 doesn't feel quite as flexible as the normal LG Gram—but it also isn't completely stiff. You can twist the screen and base ever so slightly, press down the base cover a little and when twisting the device, you may also hear some subtle creaking noises. You won't likely damage the laptop in doing so, but this isn't guaranteed. The Gram Pro 16's hinge stops at around 160°. Up until then, the display can be opened easily. The hinge holds the screen securely at every angle, but we unfortunately can't say the same about the display itself. When using the laptop outside, a small amount of wind already reveals the material's high flexibility. The screen starts to wobble.
Among the comparison devices, the LG Gram Pro 16 is the lightest, weighing about 1.3 kg. In addition, the laptop is super flat—we measured around 12 - 15 mm at different points.
This makes the manufacturer's choice of power supply unit seem out of place. On Amazon and in our drawer, we found several suitable power supply units that are significantly smaller and lighter than the 90-watt power supply unit delivered with the Gram. This is mainly due to the fact that you'll also have to carry a thick power cable with you. This combination weighs 420 grams, whereas a comparable power supply from Rocoren weighs 134 grams less including the original USB-C cable from LG—and it is significantly more compact. In a laptop where every gram is as important as in the LG Gram Pro, the power supply should also be correspondingly light.
Connectivity
The Pro version of the LG Gram is missing a card reader and a Kensington lock slot but apart from this, its connectivity options are identical to the Gram series. There are no differences between the individual LG Gram Pro models when it comes to their choice of ports.
Communication
A soldered-on Intel AX211 takes care of WLAN and Bluetooth reception inside the LG Gram Pro 16. Wi-Fi 6E connections are possible, but Wi-Fi 7 is not. Its connection speeds within the 5 GHz and 6 GHz networks are sufficient, but significantly slower than in the LG Gram Pro 2-in-1.
Webcam
The Full HD webcam inside the LG Gram Pro has to fit into the device's flat screen. Unfortunately, the small camera doesn't have the best picture quality. We mainly noticed a slight green cast in various lighting situations.
Maintenance
To unscrew the LG Gram Pro 16, you first have to remove its four rubber feet. Unlike many other LG devices, these are not glued on. The four PH0 screws underneath can be removed quickly and removing the base plate isn't all too difficult using a plastic tool. Only the two NVMe SSDs can be upgraded, but many components are still modular. You can get the corresponding spare parts from LG. It's worth taking a look at their website for battery, keyboard, screen and touchpad replacements, as well as many small parts.
Sustainability
LG ships the LG Gram Pro 16 in a cardboard box without much plastic. There is no plastic inside the box, but there is some fabric made from easily recyclable polypropylene. We have not yet received any information from LG on points such as CO₂ emissions or the use of recycled materials in this product. For many other laptops, LG now has corresponding data sheets available for everyone to view.
Warranty
The LG laptop is covered by a standard 12-month warranty in the United States. You can purchase warranty expansion plans via the manufacturer's website.
Input devices
Keyboard
The base of the LG Gram Pro has a thickness of 9 mm. This doesn't leave much room for a high key lift. Nevertheless, typing on our test device's backlit keyboard feels quite nice. Its haptics are appropriate and the keyboard isn't dented during normal use—even if the base itself is a little flexible.
Touchpad
The Gram 16's touchpad is about 13 × 8 cm in size. It is easy to work with. Clicks are recognized over almost its entire surface. Touch inputs using your fingers are precise right into the corners. The touchpad's palm recognition also works perfectly, but it can't be switched off.
Display
The LG Gram Pro 2-in-1 and the LG Gram Pro 16 both use the same 16:10 OLED panel. This model includes a 120 Hz refresh rate, HDR, 2,880 × 1,800 pixels and a brightness of about 420 cd/m². As a result, this panel gets a little brighter than the one inside the Pro 2-in-1. During our last test, the gaps between the blue sub-pixels on the panel caught our eye. Thankfully, these are a lot less noticeable without the glass pane over the panel.

* ... smaller is better
Straight out of the box, the LG Gram Pro 16's color space coverage and color accuracy are fit for professional use. Even so, the LG Gram Pro 2-in-1—fitted with the same panel—showed slightly better values. In turn, its maximum brightness was a little lower in comparison. We have often found that the brightness setting of an OLED panel can have a significant impact on color accuracy.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 481 Hz Amplitude: 41 % |  | |
The display backlight flickers at 481 Hz (worst case, e.g., utilizing PWM) . The frequency of 481 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8516 (minimum: 5 - maximum: 343500) Hz was measured. | |||
Outside, the Gram Pro 16 doesn't do too well. Its shiny display surface has to contend with some extreme reflections. You can only read from it well outside if you place something dark behind the screen.
As is typical for OLEDs, the Gram Pro 16 hardly shows any color changes when viewed from steeper angles. Only when the viewing axis is almost parallel to the screen surface do rainbow effects become apparent.
Performance
Our test device is equipped with an Intel Core Ultra 7 155H, an Nvidia GeForce RTX 3050 (4 GB GDDR6 RAM) and 32 GB LPDDR5 RAM. Two fast NVMe SSDs from Samsung also come pre-installed. Other configurations are available with 8 or 16 GB RAM, with an Intel Core Ultra 5 125H and without a dGPU.
Testing conditions
The LG Gram Pro 16 has four presets for fan and power control. We left the cooling mode set to High during most of the benchmarks. We only ran the gaming benchmarks using the mode Max.
In many different test scenarios, we found that the laptop's performance didn't remain constant in any performance mode. After a short boost phase, it took around 5 to 10 minutes for the system's performance to stabilize at a consistent level, no matter the performance preset.
Processor
The Intel Core Ultra 7 155H is a powerful processor. It can juggle 22 threads while still offering good performance capacity at low power consumption levels. However, most of the competitors have set their processor's TDP higher, resulting in our test device suffering a little in comparison. At the end of the day, you won't likely be buying an LG Gram for its particularly high computing power.
The negative effect resulting from the dGPU became visible during our Cinbench R15 loop. Even with maximum ventilation, the processor got too hot after a few runs and was throttled. The LG Gram Pro 2-in-1 showed more consistent performance. However, the equivalent cooling system in this convertible does not have to dissipate the additional waste heat of an RTX 3050.

System performance
If you place the LG Gram Pro 16 under high loads for longer periods at a time, then the cooling mode Normal will barely be enough to make working on this laptop possible. In all system performance benchmarks, the laptop even came below the LG Gram Pro 2-in-1 that only features an iGPU. This means the advantage that a dGPU can bring is not made use of fully inside our test device. In the cooling modes High and Max, the Gram Pro does get quite loud at 45 dB(A) and up to 52 dB(A) respectively.
Depending on how you aim to use the slim laptop, you might want to adjust its performance mode. During our test, we noted that the quietest mode is good enough for surfing and office applications, while 4K streaming already led to some stuttering. On the other hand, the LG Gram Pro 16's highest cooling mode has a big influence on how the system performs. This puts the laptop at least within striking distance of its in-house competitor. Also noticeable here: the Gram Pro 16 didn't outperform the 2-in-1 device without a dGPU in any of the PCMark 10 sub-sections. Even in the digital content creation section, the Gram Pro 16 couldn't achieve higher scores despite it being equipped with the RTX 3050.

DPC latencies
Chips and drivers from Nvidia and Intel seem to be slowly getting along better again. At least we didn't see any excessively high DPC latencies during this test. Nevertheless, the Gram Pro 16 is not suitable for real-time audio processing—at least according to LatencyMon.

Storage devices
Two fast SSDs from Samsung get to work inside the LG Gram Pro 16, although they are not combined using RAID. During continuous operation of the SSDs, we noted brief drops in read speeds during the test, which could indicate that the hard disk drives are overheating.

Graphics card
The Nvidia GeForce RTX 3050 in the LG Gram Pro was introduced back in May 2021. It is not the Refresh version. An RTX 4050, as installed in the HP Spectre, Galaxy Book4 Ultra and Lenovo Yoga 9, would have been more up-to-date.
In the test device, the RTX 3050 is supplied with a maximum of 45 watts. This means that 10 to 20 watts of the CPU's power is already diverted. The Gram Pro 16 doesn't have a MUX switch, which means that the Arc iGPU in the Intel Core Ultra 7 is always active. For graphics performance, its low TGP mainly means that you can expect significantly less in this respect than with all of the comparison devices. Even so, the RTX 3050 was usually still faster than the Arc iGPU, with one clear exception. 3DMark's new Steel Nomad benchmark ran significantly worse on Nvidia's graphics chip. We blame the low graphics memory for its weak performance in the benchmark which uses an extreme amount of shaders and textures. The iGPU can manage its RAM better. Using the Max cooling mode, the RTX 3050 secured itself between 200 points and 230 points when running Steel Nomad DX12, while the iGPU from Intel managed an almost consistently stable 793 points.
The benchmark results with Blender 3.3 also showed how similar the performance of Intel's chip and Nvidia's graphics card can be. The classroom scene was calculated around 60 to 120 seconds faster on Nvidia's silicone. It is difficult to estimate how much of this is due to the more mature OPTIX and Cuda APIs. Intel's OneAPI has also been around since 2020, but Cuda and OPTIX are already more than 10 years old and, as a result, are much more mature. Accordingly, the RTX 3050 in the Gram Pro 16 also has its raison d'être. Many applications are accelerated by the graphics chip from Nvidia, even if it works with a lower TGP.

Gaming performance
The LG Gram Pro's gaming performance is nice at best. At 45 watts, the RTX 3050 can't deliver the best frame rates. More than Full HD gaming at playable frame rates doesn't seem possible with current games unless you use upscaling technology. Ray tracing results in a significant reduction in frame rates. As only 16 ray tracing cores are available, this feature cannot be used sensibly—at least for gaming. In principle, it would also be possible to game using the Arc iGPU. However, this is more likely to be with activated upscaling or with frame rates reduced to 20 to 50 % compared to what the RTX 3050 achieves inside the test device. For all those who would rather opt for the Gram Pro 2-in-1 or the Gram Pro 16 without a dGPU, there is no choice but to rely on Intel's iGPU.

Emissions
Noise emissions
As already mentioned, the LG Gram Pro can be very quiet or make an unpleasant amount of noise—we measured up to 52 dB(A) at a distance of 15 cm. Thankfully, the fans hardly produce any high-frequency whistling noises, which makes their volume much more bearable. Using the cooling mode Normal, the fans' maximum noise emissions are just 33 dB(A). The High cooling mode produces up to 45 dB(A). On the other hand, the Gram Pro 16 is almost never completely silent. Still, at 26 dB(A), the quiet background noise produced by the fans is barely perceptible.

Temperature
As already noted with the LG Gram Pro 2-in-1, the matte black paint on the test device causes our non-contact thermometers to fail and display significantly higher temperatures. We therefore searched for hot spots using the Flir One Pro and measured them with the Fluke t3000 FC using K-Type thermoprobes. Despite it having a dGPU, we found slightly lower temperatures on the Gram Pro 16 than on the convertible we recently tested. Overall, none of the hot spots reached the 50 °C mark. The laptop kept its temperatures at a tolerable level even during the stress test.
(-) The maximum temperature on the upper side is 49 °C / 120 F, compared to the average of 36.9 °C / 98 F, ranging from 21.1 to 71 °C for the class Multimedia.
(-) The bottom heats up to a maximum of 48.5 °C / 119 F, compared to the average of 39.2 °C / 103 F
(+) In idle usage, the average temperature for the upper side is 27.8 °C / 82 F, compared to the device average of 31.3 °C / 88 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 23.7 °C / 74.7 F and are therefore cool to the touch.
(+) The average temperature of the palmrest area of similar devices was 28.8 °C / 83.8 F (+5.1 °C / 9.1 F).

Stress test
If you took a closer look at the logs in the performance section above, you might have noticed that hardly any values were recorded during the stress test with Prime 95 and Furmark using the cooling mode. In the end, the screen on our test device froze after around 11 minutes and it could only be used again after a forced restart. All in all, the stress test showed that the Gram clearly runs out of breath after the first 10 minutes—even at the highest fan speed—if constant maximum performance is required. The Intel Core Ultra 7 then works with around 15 watts and the RTX 3050 with 40 watts.
Speakers
The Gram 16's sound is really powerful—even coming super close to the almost perfect sound delivered by the Apple MacBook Pro 16. Bass, mids and highs are reproduced excellently. This is thanks to stereo speakers with a structured membrane, which is particularly rigid and therefore has hardly any resonance of its own.

Power management
Power consumption
LG delivers a 90-watt power supply unit with the Gram Pro 16. This reached its power limit in most measurements—at least for a short time. Our test device's power consumption values don't show any abnormalities. Only a reduced power consumption in idle mode is something we would wish for.

Runtimes
With a capacity of 90 Wh, the battery inside the LG Gram Pro holds a relatively large amount of energy. Consequently, our test device outperformed its competitors when it came to its runtimes during the WiFi web surfing test. When working with office applications and streaming, we found that the laptop also has good stamina when it is disconnected from the mains. The battery can supply power for up to 11 hours at a time.

Verdict
LG Gram stands for lightweight devices that offer the highest of quality. In terms of computing power, almost all LG Gram models feature below-average hardware. In turn, their typically low TDP values usually ensure excellent runtimes.
The LG Gram Pro 16 with the RTX 3050 is a solid laptop in many ways that more than meets the highest demands. The same as with the LG Gram Pro 2-in-1, its screen, speakers and input devices are all truly great. When it comes to its performance, however, the Gram Pro 16 wasn't able to impress us as much as its convertible sibling. Pairing the Arc iGPU with an Nvidia GeForce RTX 3050 at 45 watts is hardly a sensible choice in many respects. Intel's new iGPU is quite powerful by nature, especially when combined with a lot of fast DDR5 RAM—as is the case here. Although the RTX 3050 delivers better frame rates in all games, it also drains the processor's power somewhat. If you decide to go for an LG Gram Pro 16, then you should take a long moment to think about whether a dGPU makes sense for your own range of applications. Otherwise, the Gram Pro may be a worthwhile alternative as a convertible or a device without a dGPU.
Perhaps the most similar competitor to the LG Gram Pro 16 is the Samsung Galaxy Book4 Ultra. Samsung's laptop uses a smaller battery, but a newer RTX 4050. Even though Samsung's device is slightly better than the Gram when it comes to computing power, the latter is significantly more lightweight, slimmer and offers a longer battery life.
Particularly slim, particularly lightweight, particularly good sound: The LG Gram Pro 16 knows how to impress.
As usual with laptops from LG, computing power is being traded for weight. The laptop's benchmark results largely lag behind the competition. The Lenovo Yoga Pro 9 and HP Spectre x360 16 offer significantly more power. But whether this is only effective on paper is another matter. In our eyes, the Gram Pro 16 is more than just suitable for everyday use.
Please note: We have recently updated our rating system and the results of version 8 are not comparable with the results of version 7. More information is available here.
Price and availability
At the time of writing, the LG Gram Pro 16 with the dGPU can be purchased via the manufacturer's website for US$2,399.99.
