It combines next-generation processing with a high-refresh-rate display. This machine targets high-fidelity performance.

Slim Technical Specifications

Intel Core Ultra 9 Processing Power

The processor features a hybrid architecture with 8 performance cores and 16 efficient cores. This handles heavy gaming loads and multitasking efficiently. The NPU supports AI workloads, offering up to 36 TOPs total processor performance. Because of the 160 W maximum turbo power, verify your cooling setup is adequate for sustained loads.

NVIDIA GeForce RTX 5080 Graphics

The discrete GPU utilizes GDDR7 memory for high bandwidth. It supports NVIDIA G-SYNC to eliminate screen tearing during fast-paced gameplay. The 16 GB VRAM buffer is essential for high-resolution textures in modern titles. This hardware is ready for ray tracing workloads.

High-Refresh WQXGA Display

The 18-inch IPS-Level panel runs at 240 Hz. This provides fluid motion clarity for competitive gaming. With 500 cd/m² brightness and 100% DCI-P3 colour coverage, visuals remain sharp and vibrant. The anti-glare coating reduces reflections in well-lit rooms. It also supports Dolby Vision HDR for enhanced contrast.

Connectivity: Wi-Fi 7 & Thunderbolt 5

This model includes Wi-Fi 7 for reduced latency on compatible UK routers. For wired connections, the 2.5Gb Ethernet port ensures stable data transfer. You also get two Thunderbolt 5 ports and three USB Type-A ports. This allows for extensive peripheral expansion without needing a dock.

Memory and Storage Configuration

It ships with 32 GB of DDR5 RAM running at 5600 MHz in a dual-channel setup. This speed is crucial for reducing game load times. The 2 TB M.2 SSD provides ample space for large game libraries. Note that the maximum internal memory is 32 GB, so upgrades are limited to replacing the existing modules.

Cooling and Build Notes

The chassis is a clamshell design in Eclipse Gray. It includes per-key RGB lighting and a numeric keypad. The 380 W AC adapter supports fast charging (50% in 30 minutes). However, at 3.42 kg, this is a desktop replacement, not a lightweight travel machine.
