MSI Stealth 18 HX AI A2XWJG-035US / ASUS TUF Gaming A15 (2024) FA507UV (Ryzen 7 8845HS)

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 is a dedicated unit for running some Windows AI features without loading the CPU or GPU. ASUS also sells this chassis in Ryzen 9 8945H SKUs.

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.

140 W is the maximum GPU power when Dynamic Boost borrows budget from the CPU: 25 W is added to the sustained 115 W depending on load. This laptop GPU is not the same product as the desktop RTX 4060.

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".

144 Hz shows motion smoothly when games reach up to 144 frames per second; G-Sync matches refresh to frame rate to reduce tearing. 100% sRGB suits web and game content; it is not a wide-gamut panel.

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.

The modules are not soldered; going higher means replacing the installed modules. ASUS says memory speed varies by CPU.

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

ASUS notes that only single-sided SSDs fit the M.2 slot because of components on the motherboard.

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

The USB4 port provides 40 Gbit/s data and video out; G-SYNC is listed only for the USB 3.2 Gen 2 Type-C port. The RJ45 port does not support PoE.

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.

The MUX connects the display directly to the RTX GPU to cut game latency; Advanced Optimus can switch without a restart.

ASUS says the battery can reach 50% in 30 minutes with the proper adapter while the laptop is off. Whether the adapter is included varies by country; the USB 3.2 Gen 2 Type-C port also accepts power.

ASUS states the drivers are only compatible with Windows 11 24H2 or later.

ASUS says the testing is done under lab conditions, does not mean fitness for military use, and damage from trying to replicate the conditions is not covered by warranty.
