ASUS ROG Strix SCAR 16 (2024) G634JZR / Lenovo Legion Pro 7 16IRX9H (83DE0005US)

Intel lists 55 W base and 157 W maximum turbo power for this processor; the laptop’s actual limit is set by ASUS’s operating mode.

NVIDIA gives a 60–150 W subsystem power range for this GPU; the 175 W figure includes the 25 W added by Dynamic Boost when CPU load is low. The graphics chip is soldered to the motherboard and cannot be replaced.

175 W is the highest total graphics power Lenovo allows in this model; going above NVIDIA’s 60–150 W base range for the RTX 4080 Laptop GPU relies on Dynamic Boost 2.0. The desktop RTX 4080 is a different product.

The Mini LED backlight dims in zones; Notebookcheck counted 2,048 dimming zones on its test unit. The display supports Dolby Vision HDR.

DisplayHDR 400 is VESA’s entry-level HDR tier; it does not require local dimming, so HDR looks less striking than on OLED or Mini LED. 240 Hz and G-SYNC give smooth, tear-free motion in fast games. Lenovo notes that “IPS” may also cover similar panel types such as PLS, ADS and AHVA.

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

Both slots come filled in this configuration; upgrading memory means replacing the modules.

This configuration ships with a single module, so memory runs single-channel until a matching module is added to the second slot. Lenovo’s 32 GB limit is based on the modules it has tested.

RAID 0 combines the two drives into one volume; speed goes up, but if one drive fails all data can be lost.

PCIe 4.0 x4 allows up to 8 GB/s in theory; real speed depends on the SSD. There is no card reader.

According to Notebookcheck the Thunderbolt 4 port does not accept charging; USB-C charging goes through the other Type-C port at up to 100 W. The LAN port does not support PoE, and there is no SD card reader.

140 W charging over USB-C needs Lenovo’s own adapter; other adapters may deliver less. Up to four independent displays including the internal one are supported; Lenovo lists up to 4K/60 Hz for external outputs. Ethernet is 1 Gbit/s, not 2.5G, and supports Wake-on-LAN.

According to ASUS the battery reaches 50% in 30 minutes with fast charging. Full GPU power needs the 330 W adapter; the 100 W USB-C adapter is for light use and charging on the go.

Lenovo says Super Rapid Charge reaches 30% in 10 minutes, 70% in 30 minutes and 100% in 80 minutes. 99.9 Wh sits just under the usual airline battery limit. Lenovo quotes 10.4 hours of 1080p video playback at 150 nits.

Liquid metal transfers heat between the chip and cooler more efficiently than standard paste, which makes servicing more delicate.
