About G3D Mark

🏆 Chipversus Verdict

⚠️ Generational Difference

The Intel UHD Graphics 605 is significantly newer (2017 vs 2011). The Intel UHD Graphics 605 likely supports modern features like Ray Tracing, Tensor Cores, and DLSS/FSR upscaling, which act as force multipliers for performance. The Radeon HD 6620G lacks this hardware feature set, limiting its longevity in modern titles despite any raw power similarities.

🚀 Performance Leadership

The Intel UHD Graphics 605 is the superior choice for raw performance. It leads with a 6.7% higher G3D Mark score. However, the Radeon HD 6620G offers more VRAM, which may be beneficial for texture-heavy scenarios at higher resolutions.
