The Asus ROG Strix G18 (2025) G814 is a gaming laptop with a physical footprint of 399 x 294 mm and a thickness of 23 mm, giving it a volume of 2,698 cm³. It weighs 3,000 g and features a backlit keyboard, while its cooling relies on an active fan system rather than a fanless design. The chassis is not weather-sealed, so it offers no splash protection.
The laptop features an 18″ IPS LCD panel with LED backlighting, delivering a resolution of 2560 x 1600 px at a pixel density of 167 ppi. Its 240Hz refresh rate makes it well-suited for fast-paced content, and an anti-reflection coating helps reduce glare in varied lighting conditions. The display does not support touch input, and the system can drive up to 4 displays simultaneously including the built-in screen.
The system is powered by a 16-core, 32-thread processor built on a 4 nm process, running at a base clock of 2.5 GHz with a turbo frequency of 5.4 GHz, and supports multithreading along with 64-bit operation. Memory consists of 32GB of DDR5 RAM at 5600 MHz across two slots, which also represents the maximum supported capacity. Storage is handled by a 2048GB NVMe SSD connected via PCIe 4.0, using flash-based technology. On the graphics side, the GPU operates at a base clock of 2235 MHz and boosts to 2520 MHz, paired with 8GB of GDDR7 VRAM, delivering 23.22 TFLOPS of floating-point performance, a texture rate of 362.9 GTexels/s, a pixel rate of 121 GPixel/s, and support for DirectX 12 Ultimate; XeSS (XMX) is not supported.
In PassMark testing, the system scores 57,540 in the overall CPU benchmark and 4,452 in the single-thread result, reflecting the processor's multi-core and per-core throughput respectively. The GPU registers a PassMark G3D score of 19,987, capturing its 3D graphics rendering capability.
Wired connectivity includes two USB 3.2 Gen 2 Type-A ports, two USB 4 40Gbps ports with Thunderbolt 4 support, and a single HDMI 2.1 output, while DisplayPort, mini DisplayPort, and VGA outputs are absent. Networking is covered by an RJ45 Ethernet port alongside Wi-Fi support spanning 802.11n, 802.11ac, and both 802.11ax variants including Wi-Fi 6E, complemented by Bluetooth 5.2. The laptop includes USB Type-C connectivity and AirPlay support, but does not offer an external memory card slot.
The laptop houses a 90 Wh battery and includes sleep-and-charge USB ports, allowing connected devices to be charged even when the system is powered off or in sleep mode. It does not use a MagSafe power adapter.
Audio output is handled by stereo speakers with Dolby Atmos support, and a 3.5 mm headset jack is available for wired headphones or headsets, while two built-in microphones handle voice capture; an S/PDIF output is not included. A front camera is present, though the system lacks a fingerprint scanner, 3D facial recognition, and voice command functionality. On the graphics side, the laptop supports both ray tracing and DLSS. Motion and location sensors — including a gyroscope, accelerometer, compass, and GPS — are absent, and neither a stylus nor an optical disc drive is included.
The GPU is based on the Blackwell architecture and does not carry LHR restrictions, featuring 4,608 shading units, 144 texture mapping units, 48 ROPs, and a 128-bit memory bus with an effective memory speed of 25,400 MHz and a maximum bandwidth of 405.8 GB/s; it supports multi-display output, stereoscopic 3D, double precision floating point, OpenCL 3, OpenGL 4.6, and Intel Resizable BAR. An integrated Radeon 610M GPU is also present. On the CPU side, the processor has a 50W TDP, a clock multiplier of 25, a maximum operating temperature of 100 °C, and a locked multiplier, and it does not use big.LITTLE technology; supported instruction sets include MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2, and the NX bit is enabled for hardware-level security. The cache hierarchy consists of 1,280 KB of L1, 16 MB of L2 at 1 MB per core, and 64 MB of L3 at 4 MB per core, while the memory subsystem operates across two channels with a maximum RAM speed of 5,600 MHz and ECC memory support.
