The Tegra K1 (T124) was a landmark SoC for NVIDIA, being the first mobile processor to feature a **Unified Shader Architecture** using the same **Kepler** architecture found in desktop GeForce 700 series GPUs. It effectively bridged the gap between mobile and PC gaming, enabling support for DirectX 11 and Unreal Engine 4 on mobile devices.
