ASUS ROG Strix G18 (2024) G814JIR-N6074X / ASUS ROG Zephyrus G14 (2024) GA403UI

24 MB is 8 MB of L2 plus 16 MB of L3 cache. The processor’s integrated Radeon 780M graphics handles light work when Advanced Optimus is active.

140 W is the top of NVIDIA’s allowed power range for the RTX 4070 Laptop GPU; the 25 W Dynamic Boost share moves to the GPU when CPU load is low. The GPU is soldered to the board.

1655 MHz is the 1605 MHz boost clock plus a 50 MHz ASUS overclock. The 90 W ceiling is lower than RTX 4070 configurations in large 16–18-inch laptops and was chosen for the thin chassis. The GPU cannot be upgraded.

240 Hz shows motion more smoothly and with less blur in fast games; G-Sync matches the refresh to the frame rate to reduce tearing.

Each OLED pixel makes its own light, so blacks are fully dark; leaving static images on screen for long periods raises the risk of image retention.

The MUX switch connects the display directly to the NVIDIA GPU; Advanced Optimus switches without a restart.

Because both slots are filled, upgrading means replacing the installed modules; memory speed depends on the processor’s support.

Memory cannot be increased later, so the amount should be chosen at purchase.

There is a single M.2 slot, so more capacity means replacing the existing SSD with a larger one.

USB-C charging is supported only on the USB 3.2 Gen 2 port; the Thunderbolt 4 port does not take charge. There is no SD card reader.

There is no wired Ethernet port; independent testing listed this and the lack of Wi-Fi 7 as drawbacks.

The camera has no IR sensor for Windows Hello face recognition.

Which adapter is in the box varies by country. Performance is limited when charging over USB-C.

On battery the GPU runs at a lower limit; full performance needs the 180 W adapter.

The MUX switch connects the internal display directly to the NVIDIA GPU; Advanced Optimus does this switch without a restart.

Independent testing found the Enter and arrow keys small.
