Intel lists 55 W base and 160 W maximum turbo power for this chip; actual power in the laptop depends on HP's tuning and cooling.

HP		AMD Ryzen 9 9955HX; 16 cores / 32 threads, 2.5–5.4 GHz

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.

GraphicsNVIDIA GeForce RTX 5080 Laptop GPU; 16 GB GDDR7; Advanced Optimus

This is the laptop RTX 5080, not the desktop card. HP's product sheet does not give the GPU power limit (TGP) for this SKU. Advanced Optimus switches the display between integrated and discrete GPU without a reboot.

HP		NVIDIA GeForce RTX 5080 Laptop GPU, 16 GB GDDR7; up to 175 W with Dynamic Boost; boost up to 2287 MHz

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.

MSI
Memory32 GB DDR5-5600 (2 × 16 GB), dual-channel; 2 slots

Both slots are filled; upgrading means replacing the modules. HP does not list the maximum capacity on this page.

HP		32 GB (2 × 16 GB) DDR5-5600

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

MSI
Storage1 TB PCIe Gen5 NVMe M.2 SSD; 2 M.2 SSD slots

The second M.2 slot allows adding another SSD later.

HP		1 TB NVMe SSD (PCIe Gen4 x4)

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

MSI
Display16-inch WQXGA 2560 × 1600, 16:10, IPS, anti-glare; 60–240 Hz, 3 ms

Games need high frame rates to benefit from 240 Hz; the panel follows variable frame rates with G-SYNC.

HP		18-inch 16:10 QHD+ (2560 × 1600), 240 Hz, IPS-level panel, 100% DCI-P3

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.

The USB-C ports carry DisplayPort 2.1 for external monitors; HP does not state on this page whether they can charge the laptop itself.

HP		2 × USB4 Type-C (DisplayPort, Power Delivery 3.1); 3 × USB-A; HDMI 2.1; RJ45 2.5 GbE; SD card reader; headphone/mic jack

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.
