AMD X3D CPUs outperform Intel flagships by up to 11% in Onimusha: Way of the Sword CPU benchmarks

Benchmarking 31 CPUs in *Onimusha: Way of the Sword* exposes a clear performance hierarchy, with AMD’s X3D variants leading the pack. The Ryzen 7 9800X3D, for example, outperforms Intel’s Core i9-14900K by 11.3%, a margin that shrinks to 7.2% with the older Ryzen 7 7700X3D. This suggests that 3D V-Cache remains a potent advantage in RE Engine titles, though the gap is narrower than in other games. Engineers targeting Capcom’s engine may prioritize X3D chips for consistent high-end performance, but the diminishing returns between X3D generations (e.g., 7700X3D vs. 7800X3D) limit upgrade incentives.

A notable outlier in the results is the underperformance of AMD’s 12-core Ryzen 9 models. The Ryzen 9 7900X and 9900X lag behind their 6-core Ryzen 5 counterparts (7600X and 9600X, respectively), with the 7900X3D failing to leverage its 3D V-Cache to close the gap. This anomaly is isolated to 12-core parts, as single-CCD and 16-core models avoid the issue. The cause remains unclear, whether a firmware fix from AMD or a patch from Capcom, but it complicates hardware selection for workloads where core count is typically an asset. Until resolved, engineers may need to avoid 12-core Ryzen 9 CPUs for RE Engine titles.

Intel’s lineup shows expected scaling, with the Core i9-14900K leading its camp, but the newer Core Ultra 7 270K Plus falls short of the older Core i7-14700K by 2.9%. This discrepancy highlights Intel’s lack of optimization for RE Engine titles, as the company’s iBOT technology is unsupported in these games. For engineers, this means Intel’s latest architectures may not deliver the anticipated performance uplift in Capcom’s ecosystem. The results also underscore the importance of DDR5 memory, as the 14900K’s lead narrows or disappears with DDR4 configurations.

The benchmark’s methodology, testing at 1080p with an RTX 5090 to isolate CPU performance, reveals how *Onimusha: Way of the Sword* taxes hardware. The gameplay segment, in particular, stresses CPUs more than cutscenes, which may explain the 12-core Ryzen 9’s struggles if the engine favors fewer, faster cores. While the game runs well on a broad range of hardware (e.g., Ryzen 7 2700X nearing 90 FPS at Ultra settings), the anomalies in scaling suggest that RE Engine’s CPU demands are not uniformly predictable. Engineers should validate performance across specific scenes, as later areas of the game may introduce new bottlenecks.
