Lenovo Legion Pro 5i Gen 10 (RTX 5070 Ti, OLED) / MSI Stealth 18 HX AI A2XWJG-035US

The platform also offers the Core Ultra 7 251HX; this entry covers the Core Ultra 9 275HX configuration. The chipset is Intel HM870.

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.

TGP is the maximum power the graphics card can draw in this laptop; the same GPU at a lower TGP is slower in games. The GPU is soldered to the board and cannot be replaced.

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.

Advanced Optimus connects the display directly to the discrete GPU in games and switches to integrated graphics for desktop work to save battery.

Some configurations of the same platform use a 240 Hz OLED panel; this MTM has the 165 Hz panel.

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".

The panel is factory calibrated with X-Rite and carries TUV Rheinland low blue light and flicker-free certifications.

Memory is replaceable, but Lenovo does not support more than 32 GB on this platform.

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.

Two slots allow a second SSD; PCIe 4.0 x4 offers a theoretical 8 GB/s of bandwidth.

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

USB-C charging is limited to 100 W; 140 W needs a Lenovo-specific adapter. HDMI 2.1 outputs up to 8K 60 Hz, and the 10 Gbps USB-A port charges devices while the laptop is off.

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

The wireless card sits in an M.2 slot.

Lenovo quotes about 3.6 hours in MobileMark 30 (250 nits) and about 8.4 hours of 1080p video playback at 150 nits.

Lenovo notes that some configurations may ship without an adapter.

SD Express uses a PCIe/NVMe interface for much faster transfers with compatible cards; ordinary SD cards are still read.

The IR camera enables Windows Hello face sign-in.

99.9 Wh is just under the common airline carry-on battery limit. Full GPU performance needs the 280 W adapter.
