The LG Gram SuperSlim 15Z90RT-G.AA78F faces the competition
The LG Gram SuperSlim 15Z90RT-G.AA78F is currently displayed in promotion at Boulanger and offers an attractive configuration/price ratio for its category where it is one of the most autonomous and light while being one of the only ones to offer a screen with such faithful colors with such a recent Intel processor as well as connectivity Thunderbolt 4.

Chassis, connections, screen of the LG Gram SuperSlim 15Z90RT-G.AA78F
It has an original and yet sober and elegant look with its Neptune Blue design, very light, fine dark blue, weighing less than 1 kg, certified to the American military robustness standard MIL-STD-810H.
This versatile laptop incorporates good connectivity including 3 USB-C including 2 Thunderbolt 4, an audio port as well as Bluetooth 5.3 and Wi-Fi 6E ax modules to communicate and connect remotely wirelessly.
Some may regret the absence of HDMI video output and/or traditional USB.
In this case you can use adapters USB-C to HDMI And USB-C to USB.
Using Windows Hello technology and the Infrared webcam, you can authenticate biometrically via facial recognition.
The chiclet keyboard of course has a backlighting solution that simply needs to be activated to better distinguish its keys in a dimly lit environment.
The screen will appeal to those who wish to obtain good colorimetric accuracy because it is equipped with DCI-P3 OLED specifications also implying great black depth, minimum latency as well as significant vertical and horizontal viewing angles.
OLED induces a glossy treatment which gives punch to colors but is subject to reflections in bright environments (e.g. outdoors).
With its Full HD definition and 16:9 format, the screen is also suitable for videos.
Performance, autonomy of the LG Gram SuperSlim 15Z90RT-G.AA78F
The LG Gram SuperSlim 15Z90RT-G.AA78F may appeal to those who wish to purchase a thin, very light 15-inch laptop for everyday versatile use on the go.
Its weight, less than a kilo, makes it the lightest of the 15 inches, which makes it very easy to transport, especially since it is thin.
It will be of even more interest to nomads such as some wishing to equip themselves with a student laptop PC as it is able to last around 11 hours on battery in light use.
To offer such high autonomy, this versatile Ultrabook relies on energy-efficient components, starting with its storage obviously entrusted to an SSD.
Remember that an SSD is more energy efficient than a hard drive while being more robust, quiet and much faster.
The SSD with a large capacity of 1000 GB capable of housing multiple software and files provides much better fluidity and responsiveness on a daily basis than a hard drive.
Thanks to the SSD, starts/stops, processing and launching applications are much faster, for example, and you can access online game cards more quickly.
Although no dedicated graphics card is on board, which affects the finesse and lightness but also the heat of this PC, you can watch photos and videos but also play light to modest games with this computer.
How ? Thanks to the benefits of the Intel Iris Xe solution inserted in the processor. This one, an Intel Raptor Lake Core i7-1360P – whose TDP of 28W allows better performance than the 15W standard – is low consumption as are the 16 GB of RAM to promote autonomy.
This core delivers very good performance in everyday use.
It is also suitable for content multimedia processing using multi-core (and therefore the 12 hybrid cores of the Core i7) and RAM, such as small photo editing or video conversion processes.
Consequently, we will rather favor a PC based on a non-low consumption processor and/or an appropriate dedicated graphics card if the project is to often carry out processing operations that are intensive in processor and/or graphics resources.
