Performance Comparison

About G3D Mark

🏆 Chipversus Verdict

⚠️ Generational Difference

The RTX A400 is significantly newer (2024 vs 2015). The RTX A400 likely supports modern features like Ray Tracing, Tensor Cores, and DLSS/FSR upscaling, which act as force multipliers for performance. The Radeon R9 380X lacks this hardware feature set, limiting its longevity in modern titles despite any raw power similarities.

🚀 Performance Leadership

The Radeon R9 380X is the superior choice for raw performance. It leads with a 2.5% higher G3D Mark score. This advantage makes it significantly better for higher resolutions (1440p/4K) and graphic-intensive titles compared to the RTX A400.
