GraphicsNVIDIA GeForce RTX 5080 Laptop GPU, 16 GB GDDR7; up to 175 W graphics power including Dynamic Boost; up to 1,902 MHz AI Boost clock (1,702 + 200 MHz OC)

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.

GIGABYTE		NVIDIA GeForce RTX 5080 Laptop GPU, 16 GB GDDR7; up to 175 W with Dynamic Boost; boost up to 2287 MHz

The laptop RTX 5080 is a different chip from the desktop RTX 5080. 175 W is the top power limit for this GPU; with MSI OverBoost Ultra the combined CPU and GPU power reaches 260 W. The GPU is soldered and cannot be replaced.

Hybrid graphicsNVIDIA Advanced Optimus and G-SYNC

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.

ProcessorIntel Core Ultra 9 275HX; 24 cores / 24 threads, 36 MB cache, up to 5.4 GHz GIGABYTEAMD Ryzen 9 9955HX; 16 cores / 32 threads, 2.5–5.4 GHz

This is the Zen 5 version with 64 MB of L3 cache; the 9955HX3D with 128 MB of cache is a separate processor. AMD gives a 55 W default TDP with a 55–75 W configurable range.

MSI
Display16-inch 16:10 OLED, 2560 × 1600 (WQXGA), 240 Hz, 1 ms; 100% DCI-P3; 500 nits peak; 1,000,000:1 contrast; glossy surface

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.

GIGABYTE		18-inch 16:10 QHD+ (2560 × 1600), 240 Hz, IPS-level panel, 100% DCI-P3

The same family also has SKUs with FHD+ 144/165 Hz, UHD+ 220 Hz and UHD+ Mini LED 120 Hz panels. 240 Hz shows motion more smoothly in fast games, provided the game reaches high frame rates.

MSI
Display certificationsVESA DisplayHDR True Black 500, VESA ClearMR 10000, Dolby Vision, Pantone Validated, TÜV Rheinland Low Blue Light

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

MemoryDDR5-5600; two SO-DIMM slots, up to 64 GB

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

GIGABYTE		32 GB (2 × 16 GB) DDR5-5600

There are two SO-DIMM slots; MSI supports up to 96 GB. Actual speed depends on the memory combination and the processor.

MSI
StoragePCIe NVMe M.2; one PCIe Gen5 and one PCIe Gen4 x4 M.2 slot, up to 4 TB

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.

GIGABYTE		1 TB NVMe SSD (PCIe Gen4 x4)

Of the two M.2 slots one is PCIe Gen4 and the other PCIe Gen5 compatible; a second SSD can be added.

MSI
Left portsDC-in; RJ-45 1 Gbit LAN; HDMI 2.1; USB-A (USB 3.2 Gen 2); USB-C Thunderbolt 5 (USB4, DisplayPort 2.1, Power Delivery 3.0)

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

Right portsUSB-A (USB 3.2 Gen 2); USB-C Thunderbolt 4 (USB4, DisplayPort 1.4, Power Delivery 3.0); microSD card reader (UHS-II); 3.5 mm headphone/mic combo

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.

Battery and adapter99 Wh lithium-ion; 330 W AC adapter

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.

GIGABYTE		4-cell 99.9 Wh lithium-ion; 400 W adapter

Gaming performance is available on the adapter; power limits drop on battery.
