MSI says OverBoost Ultra can allocate up to 270 W combined to the CPU and GPU; the actual figure depends on the application.

This is the Zen 5 version with 64 MB of L3 cache; the 9955HX3D with 128 MB of cache is a separate processor. AMD gives a 55 W default TDP with a 55–75 W configurable range.

The laptop version does not share the desktop RTX 5090’s configuration or power, so its performance is not the same either.

The laptop RTX 5080 is a different chip from the desktop RTX 5080. 175 W is the top power limit for this GPU; with MSI OverBoost Ultra the combined CPU and GPU power reaches 260 W. The GPU is soldered and cannot be replaced.

Dynamic Boost shifts spare power to the GPU when the processor draws less; 175 W is the upper limit for this laptop GPU.

MSI lists VESA DisplayHDR 1000 certification and about 100% DCI-P3 colour coverage. Mini LED splits the backlight into zones, deepening blacks in dark scenes, though a faint halo can appear around bright objects.

The same family also has SKUs with FHD+ 144/165 Hz, UHD+ 220 Hz and UHD+ Mini LED 120 Hz panels. 240 Hz shows motion more smoothly in fast games, provided the game reaches high frame rates.

This configuration ships at MSI’s stated maximum; both slots are filled, so memory cannot be added, only swapped.

There are two SO-DIMM slots; MSI supports up to 96 GB. Actual speed depends on the memory combination and the processor.

MSI lists four M.2 slots: one PCIe 5.0 x4 and three PCIe 4.0 x4. This SKU ships with three drives; MSI mentions Super RAID 5 support.

Of the two M.2 slots one is PCIe Gen4 and the other PCIe Gen5 compatible; a second SSD can be added.

USB-C charging is capped at 140 W; MSI recommends a 65–140 W USB-PD adapter. Full performance needs the included 400 W adapter.

It gives vibration feedback instead of a physical click; the surface is merged into the palm rest.

The IR sensor enables Windows Hello face sign-in.

A vapor chamber spreads heat over a wide surface, helping the CPU and GPU sustain high power for longer.

The global spec table lists up to 96 GB of DDR5-6400 for this chassis; actual memory speed can vary with the module and processor combination.

MSI describes the USB-C ports as Thunderbolt 4 compatible. HDMI 2.1 outputs 8K at 60 Hz or 4K at 120 Hz. The USB-A generation differs between MSI documents, so it is not given here.

The IR camera enables Windows Hello face sign-in.

Gaming performance is available on the adapter; power limits drop on battery.
