18-inch UHD+ Mini LED gaming laptop

This 18-inch UHD+ Mini LED laptop targets creators and gamers who need desktop-class performance in a portable chassis. The 120Hz panel delivers smooth motion for competitive play and colour-accurate work. A 12-core Ryzen AI 9 HX 370 processor and RTX 5080 graphics handle heavy rendering and modern titles. The Midnight Black finish keeps the look professional.

RTX 5080 with 16 GB GDDR7 video memory

The single specification that defines this machine is the NVIDIA RTX 5080 Laptop GPU equipped with 16 GB of GDDR7 memory. That video-memory capacity determines whether the system can hold large textures, high-resolution frame buffers and AI model weights without swapping. Buyers should match this figure against the VRAM demands of their specific creative or gaming workloads.

96 GB DDR5 and 2 TB PCIe 4.0 NVMe storage

Ninety-six gigabytes of DDR5 5600 MHz memory in dual-channel configuration gives ample headroom for multitasking, virtual machines and large dataset manipulation. The 2 TB PCIe 4.0 x4 NVMe SSD provides fast boot and load times for operating system, applications and active project files. Capacity limits appear only when datasets exceed the 96 GB RAM ceiling or the 2 TB storage volume.

Questions about this item

How does the 5.1 GHz max turbo on the Ryzen AI 9 HX 370 translate to sustained performance in this chassis?

The 12-core processor reaches 5.1 GHz turbo, and Gelid GC Extreme thermal compound on the CPU and GPU helps lower temperatures to reduce throttling during heavy workloads.

What bandwidth does the PCIe 4.0 x4 link give the 2 TB NVMe SSD in practice?

The drive runs on a PCIe 4.0 x4 interface, delivering sequential read and write speeds at the full capability of that generation for fast boot and load times.

Will the 18 inch UHD+ Mini LED panel fit in a standard 18 inch laptop sleeve?

The chassis measures 15.74 by 11.41 by 0.94 inches and weighs 6.39 lbs, so a sleeve sized for typical 18 inch models should accommodate it.
