GraphicsNVIDIA GeForce RTX 5050 Laptop GPU, 8 GB GDDR7; 2662 MHz boost, 115 W TGP, 440 AI TOPS

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.

Lenovo		NVIDIA GeForce RTX 5070 Ti Laptop GPU; 12 GB GDDR7; ROG Boost 1565 MHz; 140 W (115 W TGP + 25 W Dynamic Boost)

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.

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.

ASUS
Memory16 GB (1 × 16 GB) DDR5-5600 SO-DIMM; 2 slots, dual-channel capable

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.

Lenovo		DDR5-5600; two SO-DIMM slots

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

ASUS

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

Lenovo		Two M.2 PCIe 4.0 NVMe SSD slots

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

ASUS
