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 including TGP and Dynamic Boost; boost up to 2,287 MHz

175 W is the highest GPU power MSI gives in this chassis; CPU and GPU together can draw up to 260 W (OverBoost Ultra). The desktop RTX 5080 is a separate card.

MSI
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 9955HX3D, 2.5–5.4 GHz

The processor’s stacked extra cache, called 3D V-Cache, keeps frequently used game data close, which helps frame rates especially in large open-world games.

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 UHD+ 3840 × 2400, 16:10, 120 Hz Mini LED; VESA DisplayHDR 1000; 100% DCI-P3

The Mini LED backlight dims zones individually for high HDR brightness and deeper blacks; DisplayHDR 1000 is the tier certifying 1,000-nit peak brightness. Because of the high resolution, refresh is limited to 120 Hz.

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.

GIGABYTE		—
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 DDR5-5600 (2 × 16 GB); two slots, up to 96 GB

Both slots come filled; reaching 96 GB means fitting two 48 GB modules.

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		2 TB NVMe SSD (PCIe Gen5 x4); one PCIe Gen5 and one PCIe Gen4 M.2 slot

The second M.2 slot runs at Gen4; an added SSD there tops out at Gen4 speed.

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.

GIGABYTE		—
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.

Keyboard3-zone RGB backlight, up to 1.7 mm key travel, N-key rollover

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

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

99.9 Wh is just under the limit for laptop batteries allowed on planes.

MSI

Ports—2 × USB4 Type-C (DisplayPort and PD 3.1; Thunderbolt 4 compatible); 3 × USB 3.2 Gen 2 Type-A; HDMI 2.1 (8K 60 Hz / 4K 120 Hz); 3.5 mm audio combo jack

The USB4 ports are listed as compatible with Thunderbolt 4 accessories, but MSI does not state separate Thunderbolt certification; PD 3.1 allows USB-C charging, while full gaming power needs the 400 W adapter.

MSI
Card reader and network—Full-size SD card reader (UHS-III); 2.5 Gbit Ethernet; MediaTek Wi-Fi 7; Bluetooth 5.4

UHS-III gives faster reads than UHS-II with compatible cards; the full-size slot reads camera cards without an adapter.

MSI
Audio, camera and keyboard—Dynaudio-tuned 4 × 2 W speakers and 2 × 2 W woofers; 1080p IR camera with privacy shutter; SteelSeries per-key RGB, 99 keys

The IR camera enables Windows Hello face sign-in; the physical shutter blocks the camera.
