The NVIDIA GeForce RTX 4090D is the objective winner of this comparison, securing victory in ten out of thirteen measured specifications. Its most significant advantage is its FP32 performance, which is 274% higher than that of the Intel Arc A770. While the Intel Arc A770 holds its own in two specific categories, the NVIDIA GeForce RTX 4090D demonstrates a clear and substantial lead in raw computational capability across the majority of the evaluated technical fields.

Users prioritizing maximum computational power should choose the NVIDIA GeForce RTX 4090D to leverage its superior FP32 performance. Conversely, the Intel Arc A770 is the logical choice for buyers focused on the initial purchase cost, as it offers a 79% advantage in MSRP. Selecting between these two components depends entirely on whether the user requires the high-end performance metrics of the NVIDIA card or the significant cost efficiency provided by the Intel alternative.
