HP		—
ProcessorIntel Core Ultra 9 275HX; 24 cores (8 P + 16 E), 24 threads, up to 5.4 GHz, 36 MB cache

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		Intel Core Ultra 9 275HX; 2.1–5.4 GHz

Arrow Lake-HX generation 24-core processor (8 performance, 16 efficiency) on the Intel HM870 chipset. There is no Hyper-Threading, so each core runs one thread.

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

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

HP		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
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 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".

Ports2 × Thunderbolt 4 USB-C (40 Gbit/s, DisplayPort 2.1, power delivery); 2 × USB-A 10 Gbit/s; HDMI 2.1; RJ-45; headphone/mic jack; smart pin power connector

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 × 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.
