Boost clock up to 5.4 GHz: Delivers ultra-fast responsiveness, reducing load times and ensuring smooth frame rates in CPU-intensive games.

High efficiency: Despite its performance, the chip is optimized for better thermal management, which pairs perfectly with MSI’s cooling system.

Graphics (GPU)

Graphics power comes from the NVIDIA GeForce RTX 5080 Laptop GPU with 16 GB of next-gen GDDR7 VRAM.

Supports ray tracing, DLSS 3.5, and advanced AI features for realistic graphics.

Suitable for AAA gaming at QHD+ 240 Hz, VR, and professional workloads like CAD or simulation.

Certain models may also ship with the RTX 5070 Ti, giving flexibility depending on budget.

Together, the CPU and GPU can run at a combined 260 W power draw using MSI OverBoost Ultra, ensuring the system can push performance to its maximum potential.
