The Verdict

The data indicates that the NVIDIA GeForce RTX 5080 is the clear choice for any workload requiring substantial graphics throughput. Its 56.28 TFLOPS FP32 rate, 960.0 GB/s memory bandwidth, and 84 ray tracing cores place it firmly in the high-end discrete GPU category. The RTX 5080 sits at the 87th percentile of all GPUs, with an average score of 56083, placing it slightly ahead of the AMD Radeon 8060S (55757, 0.6% ahead) and the AMD Radeon RX 6750 GRE 12 GB (55698, 0.7% ahead). It trails the AMD Radeon RX 9070 GRE (57367) by 2.2%.

The Intel Arc Graphics 4 Xe Mobile, by contrast, is an integrated graphics processor with a 25 W TDP, designed for power-constrained mobile systems. Its 50th percentile ranking reflects a mid-pack position among all GPUs, but its performance ceiling is fundamentally limited by system shared memory and a 2.355 TFLOPS FP32 rate. The RTX 5080 runs at 360 W TDP, requires a 750 W suggested PSU, and uses a 1x 16-pin power connector, making it unsuitable for the same form factor as the Intel part.

Users who need to run modern DirectX 12 Ultimate titles at high frame rates should select the RTX 5080. Users who prioritize portability and low power consumption within an integrated platform should consider the Arc Graphics 4 Xe Mobile, but the benchmark data shows no scenario where the Intel part outperforms the NVIDIA part in raw graphics performance.
