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 Laptop GPU; 8 GB GDDR7; 1595 MHz (1545 MHz boost clock + 50 MHz OC); 100 W + 15 W Dynamic Boost

Dynamic Boost shifts 15 W to the GPU when the CPU needs less, for 115 W in total. ASUS quotes the clock speed at a 55 W condition.
