Samsung Galaxy S25 may switch to Dimensity 9400 processors due to issues with Exynos 2500

The Galaxy S25 Ultra is expected to feature Qualcomm’s new Snapdragon 8 Elite processor, but the chip choice for the base Galaxy S25 and S25+ models remains uncertain. Samsung had originally planned to use the Exynos 2500 processor in some regional versions, but reports of problems with its production may force the company to switch to alternatives such as the MediaTek Dimensity 9400.

As reported by Korean publication NewsWay, Samsung’s production performance of its 3nm process has been below expectations, with data showing a yield rate of less than 20% of chips. These poor results are holding Samsung back from mass production of the Exynos 2500, which could cause the company to suffer significant financial losses – estimates suggest losses could reach 1 trillion won in the third quarter of this year alone.
Samsung’s low production rate is expected to be less than 20%.

Samsung has long tried to reduce its reliance on third-party vendors like Qualcomm through the production of its own Exynos processors. But the low yield of year-old chips on the 3nm process may force the company to rethink its strategy and seek solutions from outside vendors.
The situation reinforces rumors about the possible use of MediaTek’s Dimensity 9400 processors for the Galaxy S25 and S25+ in some regions. The Dimensity 9400 offers improved performance, power efficiency and advanced AI capabilities, making it an attractive option for Samsung.

Samsung is reportedly already testing the Galaxy S25+ with the Exynos 2500 processor for the European market, but this could just be part of an internal analysis rather than a final decision. The test results also point to lower performance of the Exynos 2500 compared to the flagship Snapdragon, which raises questions about whether the Exynos 2500 will be able to meet the demands for high-performance Galaxy models.
The final choice of chipsets may depend on how quickly Samsung resolves its 3nm chip production issues. While the Snapdragon 8 Elite remains a prime candidate for the Galaxy S25 Ultra, the MediaTek Dimensity 9400 could take the place of the Exynos 2500 in the Galaxy S25 and S25+ models.
At the very least, it could take the place of the Exynos 2500 in the Galaxy S25 and S25+ models.
