MSI
GraphicsNVIDIA GeForce RTX 5060 Laptop GPU, 8 GB GDDR7; up to 115 W with Dynamic Boost; boost up to 2497 MHz

The laptop RTX 5060 is not the same card as the desktop RTX 5060; NVIDIA lists 45–100 W for the laptop version, and MSI reaches 115 W by shifting an extra 15 W with Dynamic Boost. That is the top power class for the RTX 5060 Laptop GPU; performance depends on cooling and power mode. MSI quotes 572 AI TOPS.

MSI		NVIDIA GeForce RTX 5090 Laptop GPU, 24 GB GDDR7; 150 W maximum graphics power with Dynamic Boost; up to 1875 MHz boost

The laptop RTX 5090 is not the same card as the desktop RTX 5090. 150 W is the ceiling MSI sets for this thin chassis, so slightly lower GPU performance than thicker 175 W models is expected. MSI quotes 1824 AI TOPS.

MSI
Display15.6-inch Full HD (1920 × 1080), 144 Hz, IPS-level wide-view panel, thin bezel, anti-glare

144 Hz shows game motion more smoothly at up to 144 frames per second. US versions of the same family use a 165 Hz QHD panel; this SKU is Full HD.

MSI		18-inch UHD+ 3840 × 2400, 120 Hz, Mini LED, HDR 1000, 100% DCI-P3; matte surface

The 16:10 panel is an LCD lit from behind by many small LED zones; local dimming gives high brightness and contrast in HDR content, though halos can appear around bright objects in dark scenes. MSI’s family page describes the panel as "IPS-Level".

MSI
Memory16 GB DDR5-5600 (2 × 8 GB, dual channel); 2 SO-DIMM slots, up to 96 GB

The two modules run in dual channel; because the slots are socketed, memory can be upgraded later.

MSI		64 GB (2 × 32 GB) DDR5-5600; 2 SO-DIMM slots, up to 96 GB

Both slots come populated, so an upgrade means replacing the modules. MSI lists support up to DDR5-6400; the actual speed depends on the memory combination and the CPU.

MSI
Storage512 GB M.2 PCIe NVMe SSD; 1 × M.2 PCIe 4.0 x4 slot

This SKU has a single M.2 slot; to add storage the installed SSD has to be replaced with a larger one.

MSI		2 TB NVMe PCIe Gen4 x4 SSD; 1 M.2 slot

There is no second SSD slot; MSI advises consulting a service centre before upgrading the SSD.

MSI
Ports1 × USB-C 3.2 Gen 2 (10 Gb/s, DisplayPort and USB-PD 3.0 up to 100 W); 3 × USB-A 3.2 Gen 2 (10 Gb/s); HDMI 2.1 (4K 120 Hz, 8K 60 Hz); Gigabit LAN; 3.5 mm combo audio

The USB-C port can drive an external display and accept up to 100 W USB-PD charging; a 240 W adapter is supplied. There is no Thunderbolt or card reader.

MSI		2 × Thunderbolt 4 (DisplayPort / Power Delivery 3.1); 2 × USB 3.2 Gen 2 Type-A; 1 × HDMI 2.1 (8K 60 Hz / 4K 120 Hz); 1 × RJ45; 1 × headset combo jack

Thunderbolt 4 carries 40 Gbit/s data and video over the USB-C shaped port. This model has no Thunderbolt 5.
