The NVIDIA GeForce RTX 4090D is the objective winner of this comparison, securing victory in ten out of thirteen measured categories. Its most significant technical advantage is its shader unit count, which is 470% higher than that of the AMD RX 6750 XT. While the latter component holds its own in three specific areas, the former dominates the majority of the hardware specifications provided, establishing a clear lead in raw technical capacity.

Users prioritizing maximum hardware capability should select the NVIDIA GeForce RTX 4090D to leverage its superior shader unit count. Conversely, the AMD RX 6750 XT is the logical choice for buyers focused on the MSRP, where it maintains a 66% advantage over the alternative. Choosing between these two components depends entirely on whether your primary objective is to maximize the specific hardware advantages of the former or to capitalize on the cost-related benefits of the latter.
