Performance Comparison

About G3D Mark

🏆 Chipversus Verdict

⚠️ Generational Difference

The Radeon 540X is significantly newer (2018 vs 2011). The Radeon 540X likely supports modern features like Ray Tracing, Tensor Cores, and DLSS/FSR upscaling, which act as force multipliers for performance. The Radeon HD 6790 lacks this hardware feature set, limiting its longevity in modern titles despite any raw power similarities.

🚀 Performance Leadership

The Radeon 540X is the superior choice for raw performance. It leads with a 1.3% higher G3D Mark score. However, the Radeon HD 6790 offers more VRAM, which may be beneficial for texture-heavy scenarios at higher resolutions.
