Lenovo Legion 5i Gen 10 (15IAX10, 83F00012CF) / ASUS ROG Strix SCAR 18 (2025) G835LX

The Intel AI Boost NPU, rated at up to 13 TOPS, is built into the processor.

The cores are a mix of performance and efficiency cores; there is no Hyper-Threading, so core and thread counts are equal.

115 W TGP is among the higher power limits used for this GPU in laptops; the same RTX 5050 runs at lower power in thinner chassis. The graphics chip is soldered. Lenovo also offers the RTX 5060 and 5070 Laptop GPU in this chassis at 115 W.

1647 MHz is the 1597 MHz boost clock plus a 50 MHz ASUS overclock. 175 W is the highest total graphics power; the 25 W Dynamic Boost share moves to the GPU when CPU load is low. The GPU is soldered and cannot be upgraded.

DisplayHDR True Black 600 is the VESA tier verifying 600-nit peak brightness and very low black level on OLED panels. The panel is factory colour-calibrated and TÜV-certified for low blue light and flicker-free operation; it is not a touchscreen. The platform sheet does not list G-SYNC for this panel.

The Mini LED backlight dims in many small zones independently, which keeps dark areas dark in HDR content; it is not as precise as pixel-level OLED control.

With one module fitted at the factory, memory runs in single channel; adding a matching module to the free slot enables dual channel. The highest capacity Lenovo has tested is 32 GB.

Both slots are filled in this variant and ASUS’s stated maximum is already reached; an upgrade means replacing the modules.

A second SSD can be fitted in the free M.2 slot.

RAID 0 combines the two drives into one fast volume; if either drive fails all data can be lost, so regular backups matter. ASUS states that only single-sided SSDs are supported.

USB-C charging works only through the 10 Gbps port; the Thunderbolt 4 port does not accept power. Up to 3 external displays are supported alongside the built-in panel: HDMI up to 8K 60 Hz, USB-C up to 5K 60 Hz. There is no SD card reader.

Thunderbolt 5 can offer up to 120 Gb/s in one direction, useful for fast external storage and high-resolution monitors. Independent testing criticised the lack of rear ports.

A compatible router is needed to benefit from Wi-Fi 7 speeds.

Lenovo rates battery life at 4.4 hours in MobileMark 30 and 10.8 hours in local 1080p video playback. Super Rapid Charge goes from 0 to 30% in 10 minutes and to 70% in 30 minutes; the battery must be at least 10 °C while charging.

The 380 W adapter is needed for gaming performance; the 100 W USB-C adapter is for light use and charging on the go. ASUS notes that box contents can vary by region.

This model has no IR camera or fingerprint reader, so Windows Hello biometric sign-in is not supported.

The carried weight rises noticeably with the adapters.

Warranty length varies by country.

The MUX switch connects the internal display directly to the NVIDIA GPU to reduce latency in games; Advanced Optimus does this switch without a restart.

ASUS notes that accessories can vary by region.
