MSI Stealth 18 HX AI A2XWJG-035US / MSI Titan 18 HX AI A2XWJG-070

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.

MSI says OverBoost Ultra can allocate up to 270 W combined to the CPU and GPU; the actual figure depends on the application.

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 laptop version does not share the desktop RTX 5090’s configuration or power, so its performance is not the same either.

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".

MSI lists VESA DisplayHDR 1000 certification and about 100% DCI-P3 colour coverage. Mini LED splits the backlight into zones, deepening blacks in dark scenes, though a faint halo can appear around bright objects.

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.

This configuration ships at MSI’s stated maximum; both slots are filled, so memory cannot be added, only swapped.

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

MSI lists four M.2 slots: one PCIe 5.0 x4 and three PCIe 4.0 x4. This SKU ships with three drives; MSI mentions Super RAID 5 support.

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

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.

The IR sensor 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.

Dynamic Boost shifts spare power to the GPU when the processor draws less; 175 W is the upper limit for this laptop GPU.

USB-C charging is capped at 140 W; MSI recommends a 65–140 W USB-PD adapter. Full performance needs the included 400 W adapter.

It gives vibration feedback instead of a physical click; the surface is merged into the palm rest.

A vapor chamber spreads heat over a wide surface, helping the CPU and GPU sustain high power for longer.

The global spec table lists up to 96 GB of DDR5-6400 for this chassis; actual memory speed can vary with the module and processor combination.
