ASUS ROG Zephyrus G14 (2025) GA403WM / MSI Stealth 18 HX AI A2XWJG-035US

The processor also contains graphics and AI units; when the discrete GPU is idle, the integrated Radeon graphics drive the screen.

Arrow Lake-HX generation 24-core processor (8 performance, 16 efficiency) on the Intel HM870 chipset. There is no Hyper-Threading, so each core runs one thread.

The NPU handles AI tasks such as background blur or captions in Windows at low power. TOPS means trillions of operations per second.

The same GPU can run at up to 115 W in thicker laptops, so this thin-chassis version should be expected to perform lower. The GPU is soldered.

The laptop RTX 5090 is not the same card as the desktop RTX 5090. 150 W is the ceiling MSI sets for this thin chassis, so slightly lower GPU performance than thicker 175 W models is expected. MSI quotes 1824 AI TOPS.

On OLED each pixel makes its own light, so blacks turn fully off. DCI-P3 100% means it covers the whole cinema color space; Pantone validation is a factory color-accuracy check.

The 16:10 panel is an LCD lit from behind by many small LED zones; local dimming gives high brightness and contrast in HDR content, though halos can appear around bright objects in dark scenes. MSI’s family page describes the panel as "IPS-Level".

Memory cannot be upgraded later; the right capacity must be chosen at purchase.

Both slots come populated, so an upgrade means replacing the modules. MSI lists support up to DDR5-6400; the actual speed depends on the memory combination and the CPU.

With a single slot, adding capacity means replacing the SSD.

There is no second SSD slot; MSI advises consulting a service centre before upgrading the SSD.

There is no Ethernet port. ASUS states support for the XG Mobile GC34 external GPU.

Thunderbolt 4 carries 40 Gbit/s data and video over the USB-C shaped port. This model has no Thunderbolt 5.

Wi‑Fi 7’s wide channels and multi-link features need a compatible router.

The Type-C ports support power input; full GPU power needs the 200 W adapter.

The IR camera enables face-recognition sign-in with Windows Hello.

SD Express uses a PCIe/NVMe interface for much faster transfers with compatible cards; ordinary SD cards are still read.

The IR camera enables Windows Hello face sign-in.

99.9 Wh is just under the common airline carry-on battery limit. Full GPU performance needs the 280 W adapter.
