Snapdragon 8 Gen 3

Silicon Score:9.6 / 10

Score Synchronization: The performance rating (9.6) and graphics capability scored on Xiaomi MIX Fold 4 are directly calibrated against the empirical benchmark standards of this Snapdragon 8 Gen 3 platform.

What It Is & Microarchitecture

Engineered on TSMC 4nm (N4P) lithography, Snapdragon 8 Gen 3 introduces an asymmetrical 1+5+2 CPU cluster led by a 3.30 GHz Cortex-X4, an Adreno 750 GPU with hardware global illumination ray tracing, and an upgraded Hexagon NPU delivering 45 TOPS for local multimodal generative AI execution.

Fabrication Node & Materials

Manufactured on TSMC's refined N4P process node featuring deep ultraviolet (DUV) and extreme ultraviolet (EUV) photolithography. N4P optimizes metal pitch resistance and transistor capacitance, delivering an 11% performance improvement or a 22% power reduction over standard 4nm nodes.
