The NVIDIA RTX 3090 is the objective winner of this comparison, securing victory in eight out of twelve measured categories. Its most significant technical advantage is its FP32 performance, which is 3057% higher than that of the alternative. While the NVIDIA GeForce GT 1030 holds its own in specific areas, the sheer scale of the performance gap in computational throughput establishes the RTX 3090 as the superior component based on the provided specifications.

Users prioritizing raw computational power should select the NVIDIA RTX 3090 to leverage its massive advantage in FP32 performance. Conversely, the NVIDIA GeForce GT 1030 is the logical choice for those whose primary requirement is a lower MSRP, as it offers a 95% advantage in that specific metric. Choosing between these two components depends entirely on whether your primary objective is maximizing processing capability or minimizing the initial cost of the hardware.
