Executive Summary The 2025 mobile GPU landscape has moved beyond mere rendering. Smartphone‑tablet GPUs now serve as the central nervous system of every on‑device AI workflow, AR/VR experience, and power‑efficient compute stack . Key shifts include: GPU–SoC integration unites graphics, general compute, and AI inference within a single die, delivering up to 1.8 TFLOPs peak while staying under a 500 mW envelope. The unified shader architecture (UVA) collapses pixel, vertex, and compute pipelines, cutting context‑switch latency by ~30 % and boosting AR frame rates by 18–20 % over 2024. Memory bandwidth now drives performance: Apple’s HBM2e (1.2 TB/s) and Qualcomm’s LPDDR5X power high‑resolution textures and real‑time ray tracing for the first time on mobile. Security and privacy are baked into the driver stack—on‑device AI toggles, confidential compute enclaves, and mandatory use of Vulkan 1.3 / Metal 3 ensure that data never leaves the chip unless explicitly allowed. Business implications: vendors with higher GPU specs (Apple A17, Snapdragon 8 Gen 4) become de‑facto prerequisites for next‑gen AR/VR SDKs; developers must adopt new APIs and profiling tools; enterprises can now justify premium pricing on devices that deliver AI + graphics workloads in a single silicon package. For product managers and embedded engineers, the takeaway is simple: design around GPU‑centric power budgets,
