Dominate Windows 11 Pro gaming with up to Intel® Core™ Ultra 9 processor 275HX and up to NVIDIA® GeForce RTX™ 5080 Laptop GPU with a 175W max TGP.
Power up
Game with confidence thanks to Windows 11 Pro and up to Intel® Core™ Ultra 9 processor 275HX. Backed up by the serious gaming muscle of up to NVIDIA® GeForce RTX™ 5080 Laptop GPU and up to 32GB of DDR5-5600 RAM, the 2025 Strix G18 has the perfect amount of power to keep you gaming at peak performance. With additional features like NVIDIA® Advanced Optimus, the latest DLSS enhancements, a 2TB PCIe Gen 4 SSD, the Strix G18 is truly a force to be reckoned with.
To the limit
As a Strix machine, the G18 was designed from the ground up to push the limits of gaming performance. That means that we’ve engineered a thermal solution that gives the system room to breathe, and overclock, to its maximum potential. In Turbo mode, the G18 can reach a maximum system wattage of 230W, but when fully unlocked in Manual mode, 250W of total system power is yours to command.
Dominant force
High-performance gaming machines need high-performance processors, and up to Intel® Core™ Ultra 9 processor 275HX absolutely delivers. With 24 cores and 24 threads, this gaming and multi-tasking beast can draw up to 65W when needed, ensuring that your games always stay buttery smooth.
Next-gen graphics
Stix G18 boasts up to NVIDIA® GeForce RTX™ 5080 Laptop GPU, ensuring that you’ll get incredible framerates and visuals in all the latest games. With NVIDIA® Advanced Optimus that can intelligently switch between battery-saving and high-performance modes when you need it, and 175W max TGP with Dynamic Boost, the Strix G18 is a true next-gen gaming laptop.
NVIDIA® Advanced Optimus
With NVIDIA® Advanced Optimus, the laptop can automatically route frames from the discrete GPU directly to the display using a MUX switch, bypassing the integrated graphics. This pathing improves performance by 5-10% compared to machines without a MUX Switch, making sure you get the absolute best gaming experience—all without needing touch a single button. This automatic switching also preserves your machine's battery life, as it can dynamically transition between the high-power discrete GPU and the lower power integrated GPU. No matter what you’re doing, your machine will switch to the most optimized mode without you having to lift a finger.
Supreme Speed. Superior Visuals.
DLSS 4 massively increases performance and improves image quality for top games using the power of Al.
Game-Winning Responsiveness
NVIDIA Reflex 2 with Frame Warp gives you the ultimate responsiveness, enhancing target acquisition, reaction time, and aim precision.
True-to-Life Graphics
Experience cinematic quality visuals at unprecedented speed with full ray tracing and breakthrough neural rendering technologies.
Your Ultimate Pit Stop
We’ve completely redesigned the 2025 Strix G18 to make upgrades easier than ever. This tool-less design allows for simple access to both the RAM, SSD, and fans, and we’ve also brought our latest Q-latch system here for those SSD slots. Like an experienced pit crew, you can remove and replace your SSD and RAM in seconds, having the machine back up and running without missing a lap. A specially designed frame covers the rest of the mainboard to protect the other components, but can easily be removed with a few screws for users who want to tinker further.
ROG Nebula Display
We’ve completely revamped the cooling solution of the 2025 Strix G18 to ensure that you get the best gaming experience with your machine, every time. We’ve relocated all of the exhaust vents to the rear of the hinge, keeping warm air away from your mousing hand. The sides and bottom of the machine act as an air intake, creating a natural, efficient path for airflow. Air also flows through the keyboard deck, keeping your hands cooler during intense gaming sessions. When pairing an end-to-end vapor chamber with a sandwiched heatsink, Tri-Fan Technology, and Conductonaut Extreme liquid metal on both CPU & GPU, the 2025 Strix G18 achieves a lower noise level in Turbo Mode compared to the previous generation, while still offering the same calculated excellence you expect from a Strix machine.
Refined design
The 2025 Strix lineup has been redesigned from the ground up, built for powerful performance, maximum speed, and calculated movement, with a shape inspired by race cars that personify these same concepts. With rounded edges, a streamlined shape, and reduced seams, the 2025 ROG Strix G18 is sleeker than ever.

Full-surround Aura
The 2025 ROG Strix G18 features a full-surround RGB lightbar along the bottom of the chassis, giving you a distinct glow on your desk that syncs with your other ROG peripherals.
Seamless design
Now featuring a smoother texture for an extra premium feel, the corners of the 2025 ROG Strix G18 have been chamfered to give it a more elegant and contemporary look. With rounded edges, a streamlined shape, and reduced seams, the 2025 ROG Strix G18 is sleeker than ever.
Press the Attack
The difference between victory and defeat can be separated by a single keystroke, so the Strix G18 has a full-size keyboard designed to secure the win. Overstroke technology offers sublime work and play, reducing key actuation and improving responsiveness. Built with gamers in mind, the keyboard features spaced function keys for intuitive identification and dedicated hotkeys for quick access to essential commands. Large arrow keys allow for more accurate control in the heat of battle. A larger touchpad means easier tracking across all of your applications, while per-key RGB lighting lets you choose from millions of colors on every key for endless customization. You can also create game specific layouts via Armoury Crate, making every game feel unique.
Studio-quality Sound
Dual Dolby Atmos-powered speakers create an authentic sound stage for your games. Hi-Res audio ensures you hear your music in the same quality it was recorded. Two-Way AI Noise Cancelation processes both incoming and outgoing audio to filter any errant background noises, making sure that your calls, chats and streams come through without distraction.
All Day Endurance
We equipped the Strix G18 with a large 90Wh battery, which provides plenty of endurance for video playback and web browsing. If you’re traveling without the included power supply, it also supports USB Type-C power delivery up to 100W, allowing you easily top up a charge while on the go.
All the bandwidth
Connectivity is everything in a high-performance machine, so we’ve spared no expense with the Strix G18’s feature set. With support for the latest Wi-Fi 7 standard, offering download speeds up to 2.4X times faster than Wi-Fi 6, onboard 2.5G ethernet, and dual Thunderbolt™ 5 ports, this machine puts even many desktop battlestations to shame. We’ve also included a FHD camera with Windows Hello support, allowing you to unlock the machine possible with just a smile.
Incredible I/O
Ports allow you to connect your mouse, headset, or even an external monitor, so we gave the Strix G18 an incredibly flexible I/O that can adapt to any situation. On the right side you’ll find two USB-A ports, but the left side offers the bulk of the connections, with an audio jack, dual Thunderbolt™ 5 ports (USB Type-C), a single USB-A, HDMI 2.1, a 2.5G ethernet port, and the power port. If you can imagine your ideal battlestation, the Strix G18 can make it a reality.
Endless Customization
When you want to tweak settings, monitor temperatures, or tinker with your laptop, Armoury Crate is your command center. Real-time monitoring allows you to see what your GPU, CPU and memory are doing. RGB can be adjusted on a game-by-game basis with Aura Sync. Fan and power profiles allow you to change the acoustics, power delivery, and thermal characteristics of the laptop on the fly. And exclusive game deals keep your library topped off at all times.
More than just simple fan curves, Armoury Crate’s performance modes serve to transform your machine from a silent, power sipping web browser to a full gaming battlestation with maximum horsepower. And for those that require even more granular control, Manual mode removes all limiters and lets you make a custom profile that suits your exact needs.
