About G3D Mark

🏆 Chipversus Verdict

⚠️ Generational Difference

The Radeon RX Vega 3 is significantly newer (2019 vs 2013). The Radeon RX Vega 3 likely supports modern features like Ray Tracing, Tensor Cores, and DLSS/FSR upscaling, which act as force multipliers for performance. The Radeon HD 7640G + HD 8670M Dual lacks this hardware feature set, limiting its longevity in modern titles despite any raw power similarities.

🚀 Performance Leadership

The Radeon RX Vega 3 is the superior choice for raw performance. It leads with a 1% higher G3D Mark score. However, the Radeon HD 7640G + HD 8670M Dual offers more VRAM, which may be beneficial for texture-heavy scenarios at higher resolutions.
