According to a Weibo post by Smart Chip Insider, Samsung has begun internal development of custom CPU and GPU architectures, with plans to reintroduce them in the upcoming Exynos 2800. The move follows the shutdown of Samsung’s earlier custom CPU effort after the Mongoose cores failed to meet expectations.
From Mongoose to a fresh start
Samsung previously pursued fully custom CPU cores under its Exynos lineup, most notably the Mongoose architecture. Performance and efficiency issues led the company to abandon those designs, and the Austin-based CPU team behind the project was laid off. Since then, Exynos processors have relied on standard ARM CPU cores and third-party GPU solutions.
Samsung is developing its own CPUs and GPUs again for Exynos 2800
The new report suggests Samsung is now reversing course. The company is reportedly developing proprietary CPU and GPU designs internally, with the Exynos 2800 targeted as the first platform to adopt them. No technical specifications, performance data, or production timelines were shared in the post.
Why this matters
Bringing CPU and GPU design back in-house could give Samsung tighter control over performance, power efficiency, and long-term differentiation across its Exynos processors. It would also place Samsung closer to rivals that rely on deeper vertical integration in mobile silicon.
Conclusion
If the report is accurate, Samsung developing its own CPUs and GPUs again would mark a significant reset for its Exynos strategy. Targeting the Exynos 2800 for a return to in-house silicon suggests Samsung is once again prioritizing long-term control over performance and differentiation after the Mongoose setback. However, with no official confirmation or technical details from Samsung, the development remains unverified and should be viewed cautiously until the company provides a formal update.
