18-inch WQXGA 240Hz gaming laptop

The ASUS ROG Strix G18 is an 18-inch gaming laptop built around an AMD Ryzen 9 8940HX processor with 16 cores and 32 threads. It pairs that CPU with an NVIDIA GeForce RTX 5070 laptop GPU carrying 8GB of GDDR7 memory. The 2560 x 1600 panel refreshes at 240Hz and runs Windows 11 Home out of the box.

Thermals noise and power draw

The chassis measures 15.71 x 11.57 x 0.91 inches and weighs 6.61 lbs, giving the internal cooling array room to move air across both the 5.3 GHz boost clock and the discrete graphics. A 16GB DDR5 configuration keeps memory power modest while the 512GB PCIe SSD adds negligible thermal load during typical gaming sessions.

Build integration and expansion

Two USB4 Type-C ports each deliver up to 40Gbps and support DisplayPort, G-SYNC and power delivery on one of them, while HDMI 2.1 FRL drives external high-refresh displays. RJ45 LAN, two USB 3.2 Gen 2 Type-A ports and a 3.5mm combo jack round out the wired connectivity, and Wi-Fi 6E with Bluetooth 5.3 handles wireless duties.

Questions about this item

How do I install extra DDR5 memory in the SO-DIMM slots, and which step do people often miss?

Open the bottom panel, insert the DDR5 stick at an angle until it clicks, then lock it down; the step most people miss is pressing the module firmly until both side clips snap into place.

When will the 512GB PCIe SSD need replacement, and what should I watch for?

Plan to replace the 512GB PCIe SSD when write endurance nears its limit or capacity runs low; watch for slowing write speeds or SMART warnings.

What thermal limit appears first during long gaming sessions on the Ryzen 9 8940HX?

The Ryzen 9 8940HX hits its 5.3 GHz turbo ceiling first, then power and temperature limits throttle clocks to protect the 16-core CPU.
