Release year20252023
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 4060 Laptop GPU; 8 GB GDDR6; ROG Boost 2300 MHz; 125 W (100 W + 25 W Dynamic Boost)

2300 MHz is the 2250 MHz boost clock plus a 50 MHz ASUS overclock; ASUS says it measured this with FurMark in a 25 °C lab. The graphics chip is soldered and cannot be upgraded.

ASUS
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.

The chip also includes Radeon 780M integrated graphics.

ASUS
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		14-inch QHD+ (2560 × 1600, 16:10); IPS-level, anti-glare; 165 Hz; 3 ms; DCI-P3 100%; Pantone Validated

DCI-P3 100% covers the cinema colour space; Pantone Validated means colour accuracy was checked at the factory. This SKU does not have the mini LED Nebula HDR display.

ASUS
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		16 GB DDR5 (soldered on board); 1 × DDR5 SO-DIMM slot; up to 32 GB

Memory can be increased by fitting a module in the SO-DIMM slot alongside the soldered memory.

ASUS
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		512 GB PCIe 4.0 NVMe M.2 SSD; 1 × M.2 slot

With a single M.2 slot, capacity is increased by replacing the SSD with a larger one.

ASUS
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.
