Gigabyte Aero 15 OLED XD laptop review: Next-generation 4K OLED
The Gigabyte Aero series focuses on multimedia as well as content creation; therefore, it tries to cater to the high requirements of graphic designers and media designers. There's also some room for gaming in the Aero series, because since Nvidia has given manufacturers the freedom to influence the performance (TDP) of the RTX 30XX graphics cards, powerful GPUs, such as the RTX 3070 found in our review unit, have also found a place.
As not much has changed externally, we will refer to the review of the Gigabyte Aero 15 OLED XC in the corresponding sections of our review.
We choose the competing devices listed below for the comparison, to which additional laptops can be added under each section.

Case - Identical to the predecessor except for minor modifications
Since the case hasn't changed much compared to the predecessor, we refer to the Gigabyte Aero 15 OLED XC here. Only the pattern of the display lid's surface has undergone a change. It's also worth mentioning that the lid closes automatically when it has an aperture height of around 10 centimeters or below. In addition, the display lid's upper bezel is recessed, which makes it easier to lift the lid.
The size and weight haven't changed, either. If you compare the test device with the competition, the Aero 15 OLED XD stands out with the lowest weight and a height of two centimeters.
Connectivity - Same ports, upgrade to Thunderbolt 4
The Aero 15 OLED XD is equipped with all the ports a creator could need. These include a full-fledged SD card reader and an Ethernet port. The fact that Gigabyte has managed to integrate a complete Ethernet port into the slim chassis is remarkable! Unfortunately, however, nothing has changed in comparison to the predecessor apart from the addition of the Thunderbolt 4 port. We would have wished for a better placement of the ports on the right, since working with a mouse is difficult when the power adapter, the Thunderbolt 4 port, and the two USB Type-A ports are in use. Unfortunately, Gigabyte sacrificed the entire rear section in favor of the cooling system, where at least the power supply is usually found.
SD card reader
The Aero 15 OLED XD has a full-fledged SD card reader that delivers good results with our 128 GB UHS-II AV PRO V60 microSD reference memory card. The predecessor managed about 10% higher performance with the Toshiba Exceria Pro at the same read speed.

Communication
Gigabyte keeps using the Intel AX200 WLAN module, which supports Bluetooth 5.1 and Wi-Fi 6 among other things (the rates are still slightly higher than with the predecessor). In comparison, the Asus TUF Gaming A15 outperforms our review sample by 19% in the data transfer test and even by a whole 40% in the data reception test.
Webcam
The selection of the webcam's position raises a few questions on our part. Although there's a manual switch here to hide the webcam, it has an inferior quality compared to the case. Furthermore, it provides an unfavorable viewing angle from below. Anyone who's dependent on a webcam would wish for a better one here. Above all, there would have been enough room for a larger sensor and a resulting improvement in resolution. In our opinion, the narrow display bezel could have been forgone in the top area in order to at least provide a webcam in a normal position.
Maintenance
In order to be able to open the case, 12 Torx TR6 screws need to be removed. Like in the predecessor, two of them are covered with seals. Judging from experience, Gigabyte probably wants to make it more difficult to open the device or to indicate whether the device has been opened in warranty cases. This also makes it difficult to replace the SSD, RAM, and WLAN module. Other components can't be replaced easily and with little effort. At least Gigabyte has made full use of the space in the Aero 15, allowing users to install a second M.2 SSD as a result.
Warranty
Gigabyte Germany offers users a two-year warranty period. If you want to extend the warranty, you have to register the device online.
Input devices - Keyboard once again lacks illumination for special characters
Keyboard
The Aero 15 OLED XD has a full-sized keyboard with normal-sized keys. The user will experience a rather mushy typing experience and a rather poor and imprecise pressure point. The key volume is average and could be perceived as being too loud by sensitive users. We noticed a "squeaking" noise when pressing the space bar lightly. In addition, it feels very wobbly, which often led to typos when entering longer text passages. Gigabyte could have learned from its predecessor when it comes to the individual RGB lighting, because once again, the keyboard's special characters are not illuminated. As a result, it's hard or even impossible to recognize the special characters at night or in poor lighting conditions, something that we found to be quite annoying. Furthermore, the keyboard is very susceptible to fingerprints.
Touchpad
As in the predecessor, the touchpad is compact but offers good gliding properties. The integrated fingerprint sensor further hinders the use of the already small touchpad. The integrated mouse buttons have a clear pressure point and decent feedback. The touchpad is also susceptible to fingerprints.
Display - Fantastic 4K OLED panel with 60 Hz
The 4K AMOLED panel used has a resolution of 3840x2160 pixels and features a Pantone X-Rite certification, which makes the device particularly appealing for designers and professional image editors. The resulting color accuracy combined with the OLED panel delivers a very good picture. Gigabyte gets almost everything right here, as the high resolution provides more space on the display. This also becomes noticeable when editing videos, for instance with a longer timeline in Adobe Premiere.
Unfortunately, there is no 120 Hz option. The built-in panel only comes with a 60 Hz refresh rate, which puts users at a disadvantage when playing fast-paced games.
As is usual for OLED panels, brightness is regulated using PWM. Since the frequency here is low at 240 Hz, users can suffer from eye strain, headaches, and nausea during longer workflows.

* ... smaller is better
The glossy 4K display is razor-sharp, and all other values, such as the black level and contrast ratio, also deliver fantastic scores thanks to the OLED technology. With our measurement, we can also confirm that the laptop is very well suited for digital image and video editing. With a coverage of 100% and 99.5%, respectively, the sRGB and AdobeRGB color spaces are (almost) completely covered.
When it comes to display brightness, you get good rates here. The brightness distribution is 92%, and the maximum brightness is about 446 cd/m² according to our independent measurements.
Outdoor use is possible with the Aero 15 OLED XD, but you should look for a place in the shade, because the display offers a high brightness, but it's also reflective.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 240 Hz | ≤ 83 % brightness setting |  |
The display backlight flickers at 240 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 83 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 240 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8684 (minimum: 5 - maximum: 343500) Hz was measured. | |||
Thanks to the OLED panel, the viewing angles of the Aero 15 are excellent in all directions.
Performance - Future-proof performance package
Our test device is equipped with an Intel Core i7-11800H, a laptop version of the GeForce RTX 3070 with a 105-watt TDP, and an NVMe SSD. In addition, there's 32 GB of DDR4-3200 RAM that runs in dual-channel mode. With this package, Gigabyte provides customers with sufficient performance for all common multimedia applications as well as for all the performance-hungry programs needed for video and image editing.
Processor
The processor used here is the Intel Core i7-11800H: An octa-core CPU from Intel's current Tiger Lake portfolio that is suitable for gaming laptops as well as workstations. The eight processor cores can run at clock rates from 2,300 MHz to 4,600 MHz and process up to 16 threads.
Gigabyte has deliberately chosen Tiger Lake instead of AMD with creators in mind. Video editing is even faster thanks to Intel's Quick Sync technology. The performance offered is very high, but it can't fully keep up with the AMD 5900HX.
A closer look at the hardware inside revealed that the chipset has been equipped with passive cooling. Besides that, Gigabyte works with the Windforce Infinity Next Gen cooling system here, which is equipped with four heat pipes, two of which share the GPU's and CPU's waste heat. The two razor-sharp fans have 71 blades.
Our CPU Benchmarks article shows whether the performance of other laptops can keep up in comparison.

System performance
In the PCMark 10 benchmarks, which simulate daily work on the computer and then measure how powerful the device is based on various categories, our test device shows excellent scores. All competing devices are outperformed in the overall score. What's interesting is that the 11800H used here in combination with 32 GB of DDR4-3200 RAM and the fast NVMe SSD even leaves the ASUS ROG Strix G15 G513QR with the AMD Ryzen 9 5900HX behind.

DPC latencies
Contrary to expectations for the laptop's intended purpose, Latency-Mon shows problematically high DPC latencies in AI mode, indicating that the laptop isn't suitable for editing video and audio files in real time. Upon closer inspection, we discovered that this is probably due to the Control Center settings. In the Creator, Gaming, and AI modes, the values are too high according to the tool. Apparently, the only solution is to turn on Turbo mode, which is quite loud, though.

Storage
By using a suitable NVMe SSD connected via PCI Express Gen 4, the Aero 15 OLED XD outperforms the entire competition in our storage tests and offers very good rates. The OEM sibling of the Samsung 980 Pro, the Samsung PM9A1, achieves 7,000 MB per second in the SeqWrite test and over 5,000 MB per second in the SeqRead test in CrystalDiskMark. Gigabyte also has creators in mind here by offering the option of installing another NVMe SSD. However, this is only connected via PCI Express Gen 3.

Graphics card
Our configuration of the test device uses a laptop version of the Nvidia GeForce RTX 3070 that has a TDP of 105 watts. If you let Gigabyte's Control Center's Microsoft Azure AI automatically manage the performance profiles, the maximum performance is not achieved, and the 3DMark scores are even slightly lower than those of the predecessor. Our recommendation is to manually switch to Turbo mode for titles that require maximum performance. In some cases, the fan control of the different performance profiles is not optimized. The fans don't respond fast enough when manually switching to Game mode at times, which can lead to unwanted performance drops.
Generally, we weren't able to achieve full performance on battery power. Furthermore, the Nvidia Studio driver for creators does its job, and there's only a minor difference compared to the gaming driver.
The performance offered by other graphics cards that we've tested can be found in our GPU Benchmarks article.

Gaming performance
Thanks to the RTX 3070 with its 105-watt TDP and the great 4K display, the Gigabyte Aero 15 OLED XD is also suitable for 4K titles. If you tweak the details a bit, you'll achieve smooth frame rates in almost every game. Compared with the competition, the manufacturer delivers a somewhat inconsistent, but high performance. In some titles, our test device even beats devices with a higher TDP, such as the Asus Strix G15 G513QR. Unfortunately, the Aero 15 OLED XD doesn't come close to the Alienware m15 R4's performance. If you compare it with the older Gigabyte Aero 15 OLED XC, its performance is identical to the successor. However, there's no 120 Hz panel here, but only one with 60 Hz. This more or less automatically disqualifies the laptop for competitive gaming, since you would have to connect an external monitor to prevent disadvantages.
