The NVIDIA GeForce RTX 4090D is the objective winner of this comparison, securing victory in ten out of thirteen evaluated specifications. Its most significant advantage is its FP32 performance, which is 1651% better than that of the Intel Arc A380. While the Intel Arc A380 holds its own in two categories, the massive lead in raw computational power makes the NVIDIA GeForce RTX 4090D the superior choice for high-end technical requirements.

Users prioritizing maximum computational throughput should select the NVIDIA GeForce RTX 4090D to leverage its substantial lead in FP32 performance. Conversely, the Intel Arc A380 is the appropriate choice for budget-conscious buyers, as it offers a 92% advantage in MSRP. Choosing between these two components depends entirely on whether your primary objective is to minimize initial expenditure or to maximize the raw processing capabilities of your graphics hardware.
