The NVIDIA GeForce RTX 5090D is the objective winner of this comparison, securing victory in eight out of thirteen measured categories. Its most significant technical advantage is its shader unit count, which is 844% higher than that of the Intel Arc B570. While the Intel Arc B570 holds its own in four specific areas, the substantial lead in core processing architecture makes the NVIDIA GeForce RTX 5090D the superior choice for raw hardware capability.

Users prioritizing maximum computational power should select the NVIDIA GeForce RTX 5090D to leverage its massive shader unit advantage. Conversely, those focused on initial acquisition costs should choose the Intel Arc B570, which offers a 90% better MSRP. The decision rests on whether the buyer requires the high-end processing capacity provided by the former or the significant cost efficiency offered by the latter.
