MSI Raider 16 Max HX / MSI Stealth 18 HX AI A2XWJG-035US

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 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".

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.

The sheet says values may vary by scenario.

Actual speed depends on the memory combination and CPU support.

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

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

The sheet mislabels the unit as mm; another MSI regional sheet for the same chassis lists 363 x 269.7 x 21.95-28.85 mm.

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.

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

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.
