The Verdict

The data clearly shows that the NVIDIA GeForce RTX 4080 Mobile is the superior performer in every measurable aspect. Its compute throughput, memory bandwidth, and benchmark scores place it far ahead of the Intel Arc A380E x2. The RTX 4080 Mobile's 24.72 TFLOPS FP32 performance is three times the combined output of two Intel Arc A380E GPUs. Its 432.0 GB/s memory bandwidth exceeds the combined 372.0 GB/s of the Intel pair. The benchmark percentile of 81 versus no recorded percentile for the Intel part further confirms this gap.

The RTX 4080 Mobile is appropriate for users who need high-end graphics performance in a portable form factor. Its 12 GB memory capacity and 58 RT cores support demanding workloads such as ray tracing and large textures. The Intel Arc A380E x2, by contrast, appears designed for specialized multi-display or embedded applications. Its 8x mini-DisplayPort 2.0 outputs and single-slot design suggest use cases involving many monitors or dense GPU arrays. The lack of benchmark data for the Intel part indicates it is not positioned for general-purpose gaming or compute workloads.

For those choosing between these two products, the RTX 4080 Mobile is the clear choice when performance is the priority. The Intel Arc A380E x2 offers no performance advantage in any recorded metric. Its only potential benefits are the multi-output display capability and the ability to run two GPUs in a single system, but these do not compensate for the massive compute deficit. The RTX 4080 Mobile's nearest rivals show it performs within 1.3% of the RTX 4070 and Tesla P4, and within 0.6% of the RTX 5080 Mobile, indicating it sits in a competitive high-end bracket. The Intel part has no comparable positioning in the database.
