The Asus ROG Strix Scar 18 (2025) is classified as a gaming laptop with a physical footprint of 399 × 298 mm and a thickness of 23 mm, giving it a volume of 2,734.746 cm³. It weighs 3,480 g, which is typical for a large-chassis gaming machine of this screen size. The laptop features a backlit keyboard to aid visibility in low-light conditions, while active cooling is present as the design does not use a fanless configuration. It is not weather-sealed, so it offers no splash protection.
The display measures 18″ and renders at a resolution of 2560 × 1600 px, resulting in a pixel density of 167 ppi. An anti-reflection coating is applied to the panel surface to reduce glare, though the screen does not support touch input. The GPU is capable of driving up to 4 displays simultaneously, extending output well beyond the built-in panel.
The processor runs across 24 threads with a core configuration of 8 × 2.7 GHz and 16 × 2.1 GHz, reaching a turbo clock of 5.4 GHz, and is built on a 4 nm semiconductor process with multithreading and 64-bit support. System memory stands at 32GB of DDR5 running at 5600 MHz across two slots, expandable to a maximum of 64GB, while 2048GB of NVMe flash storage handles local data via a PCIe 4 interface. On the graphics side, the GPU carries 16GB of GDDR7 VRAM and delivers 23.04 TFLOPS of floating-point performance, with a base clock of 975 MHz boosting to 1500 MHz, a texture rate of 384 GTexels/s, a pixel rate of 144 GPixel/s, and full support for DirectX 12 Ultimate; XeSS is not supported.
In CPU benchmark testing, the system achieves a PassMark multi-core score of 56,426, reflecting the processor's throughput across all available threads, while the single-core PassMark result comes in at 4,723, indicating the per-core processing capability.
Wired connectivity includes three USB 3.2 Gen 2 Type-A ports, two USB 4 40Gbps Type-C ports, and a single RJ45 Ethernet port, while video output is handled by one HDMI 2.1 port; there are no DisplayPort, mini DisplayPort, or VGA outputs, and no Thunderbolt 3 or 4 ports. Wireless options cover Wi-Fi 7 (802.11be) along with backward-compatible Wi-Fi 6E, 6, 5, and 4 standards, paired with Bluetooth 5.4, and AirPlay is also supported. An external memory card slot is not included, and no VGA connector is present.
The laptop is equipped with a 90 Wh battery and supports sleep-and-charge functionality, allowing connected USB devices to be charged even when the system is powered off or in sleep mode. A MagSafe power adapter is not included or supported.
Audio is handled by stereo speakers with Dolby Atmos support and a 3.5 mm headset jack, while two built-in microphones and a front camera facilitate video calls; the camera is accompanied by 3D facial recognition for authentication, though a fingerprint scanner is not present. On the graphics side, the GPU supports both ray tracing and DLSS, enabling hardware-accelerated lighting and AI-based upscaling in compatible titles. The laptop does not include a stylus, S/PDIF output, optical disc drive, or motion and location sensors such as a gyroscope, accelerometer, compass, or GPS, and voice commands are not supported.
The CPU is a laptop-type processor mounted in a BGA 2114 socket with a clock multiplier of 27, an unlocked multiplier, Turbo Boost version 2, a maximum operating temperature of 105 °C, and a TDP of 80W; it uses big.LITTLE technology, includes integrated graphics, supports ECC memory across 2 memory channels with a maximum RAM speed of 6400 MHz, and carries 36 MB of L3 cache and 40 MB of L2 cache alongside instruction set support for MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2, plus an NX bit. The Blackwell-architecture GPU features 7,680 shading units, 256 TMUs, 96 ROPs, a 256-bit memory bus, a native memory speed of 2000 MHz reaching an effective 25,400 MHz, and a maximum memory bandwidth of 811.5 GB/s; it supports multi-display output, stereoscopic 3D, Double Precision Floating Point, OpenCL 3, OpenGL 4.6, and Intel Resizable BAR, and does not carry LHR restrictions. The system also supports Turbo Boost and big.LITTLE hybrid core scheduling on the CPU side, and the GPU's compute capabilities extend to the full Blackwell feature set without hardware-level hash-rate limiting.
