About G3D Mark🏆 Chipversus Verdict
⚠️ Generational Difference
The T400 is significantly newer (2021 vs 2012). The T400 likely supports modern features like Ray Tracing, Tensor Cores, and DLSS/FSR upscaling, which act as force multipliers for performance. The Radeon HD 7970M lacks this hardware feature set, limiting its longevity in modern titles despite any raw power similarities.
🚀 Performance Leadership
The Radeon HD 7970M is the superior choice for raw performance. It leads with a 1.5% higher G3D Mark score. This advantage makes it significantly better for higher resolutions (1440p/4K) and graphic-intensive titles compared to the T400.
