ASUS ROG Strix G16 (2025) G615LR / Lenovo LOQ 15IRX9 (83DV00K6UK)

HX processors are high-power mobile chips; sustained power and fan noise depend on Lenovo’s power modes.

140 W is the maximum total graphics power; the 25 W Dynamic Boost portion is shifted to the GPU when processor load is low. Real power in games varies with profile and temperature.

TGP is the sustained power limit given to the GPU; on the same GPU a higher TGP usually means higher gaming performance. Lenovo ties TGP on this platform to the wattage of the bundled adapter.

The MUX switch connects the internal display directly to the NVIDIA GPU to cut latency in games; Advanced Optimus makes that switch without a restart.

Memory is socketed, so it can be upgraded later; the shipped capacity varies by SKU.

Memory is not soldered; both slots come filled, so an upgrade means replacing both modules. The 32 GB limit is Lenovo’s platform statement.

The shipped SSD capacity varies by SKU; the second slot can be used to add a drive later.

The second M.2 slot allows an extra SSD. QLC flash can slow down sooner than TLC during long, large writes.

ASUS also lists FHD+ 165 Hz and 300 Hz panel options in the family; check the panel of the specific SKU being bought.

144 Hz shows smooth motion up to 144 frames per second in games; G-SYNC matches the refresh to the GPU’s frame rate to reduce tearing.

Which layout ships depends on the SKU; ASUS’s table does not split this per model.

Charging over USB-C works, but 140 W input needs Lenovo’s own adapter; the slim-tip port remains the main power input for gaming. There is no Thunderbolt or USB4.

USB-C delivers at most 100 W, below what the 280 W or 380 W adapter supplies.

As this version has the RTX 5070 Ti, the GPU also gets liquid metal.

Lenovo rates it at 4.1 hours in MobileMark 25 and 5.6 hours of local 1080p video at 150 nits.
