GIGABYTE AORUS MASTER 16 AM6H (BYHC5USE64SH) / MSI Stealth 18 HX AI A2XWJG-035US

175 W includes the share Dynamic Boost shifts to the GPU when CPU load is low; GIGABYTE notes the figure may vary by scenario. The desktop RTX 5080 is a different card.

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.

Advanced Optimus switches the display between integrated graphics and the RTX GPU without a reboot: a direct GPU path in games, battery savings in light work.

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.

240 Hz shows motion more clearly in fast games and puts the RTX 5080’s high frame rates on screen; 500 nits is an HDR peak, not sustained full-screen brightness.

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".

True Black 500 certifies HDR peak brightness of 500 nits together with OLED’s deep blacks; ClearMR 10000 is a motion-clarity tier.

Memory is not soldered. The BYHC5USE64SH ships with 2 × 16 GB, so both slots are filled and upgrading means swapping modules.

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.

A second SSD can be added. The Gen5 slot gives higher sequential speeds with a compatible Gen5 SSD; which slot the factory SSD uses can vary by configuration.

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

The Thunderbolt 5 port suits high-bandwidth external SSDs, docks and DisplayPort 2.1 monitors; HDMI 2.1 supports high-refresh TVs and monitors.

The two USB-C ports differ in speed and display version; for a high-resolution external display the left Thunderbolt 5 port is the better choice.

N-key rollover means every simultaneously pressed key is registered, avoiding missed inputs in games. Lighting is set in three zones, not per key.

99 Wh is close to the upper limit for laptop batteries allowed on planes. Full GPU power needs the 330 W adapter; USB-C charging via Power Delivery 3.0 is possible but performance is reduced.

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

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.
