The RX 7800M's nearest rivals in the database illustrate where its average score of 27883 lands. The AMD Radeon Pro Vega 20 scores 27839, a delta of 0.2% behind. The AMD Radeon Pro W5500X scores 27973, placing it 0.3% ahead of the RX 7800M. The NVIDIA GeForce GTX 980 Ti scores 28020, 0.5% ahead. The AMD FirePro S7150 scores 28117, 0.8% ahead. These narrow deltas show the RX 7800M clustering with a group of older workstation and enthusiast cards, despite its modern architecture and high compute figures.

The Arc A380E x2 has no nearest rivals and no benchmark entries, so direct head-to-head scores cannot be computed. The database records zero wins for either product in head-to-head tests, as no overlapping test data exists. The analysis must therefore rely on the architectural and specification differences recorded in the database.
