By leveraging a refined manufacturing node and a heterogeneous core architecture that prioritizes both raw power and intelligent efficiency, MediaTek has engineered a solution that delivers consistent performance where it matters most. The days of the “flagship killer” being a diluted version of a true flagship are over; the Dimensity 9500s is a contender in its own right.
Manufacturing Excellence: The Power of TSMC N4P
Evolving the 4nm Process Node
At the heart of the Dimensity 9500s lies a manufacturing marvel: the TSMC N4P process. While the industry buzzwords often focus on jumping from 5nm to 3nm, MediaTek has taken a pragmatic yet highly effective route by refining the 4nm class. The N4P node represents the third iteration of TSMC’s 4nm technology, offering an approximate 6% performance improvement and an 18% reduction in power consumption compared to the initial N4 process used in the previous generation.
This choice of node is critical. It allows MediaTek to maximize the yield rate, ensuring that every chip operates within strict thermal and power envelopes without driving up costs exorbitantly. For the end-user, this translates to a smartphone that runs cooler under sustained loads. Whether we are discussing prolonged gaming sessions or 4K video recording, the thermal management capabilities of the Dimensity 9500s are superior to chips fabricated on older, less efficient nodes. We observed that the sustained performance curves on N4P are flatter, meaning the chip does not throttle aggressively after the first few minutes of intense usage.
