In a move that could redefine the competitive landscape of mobile silicon, Samsung is reportedly gearing up for its most ambitious chip project to date. According to multiple industry reports, the tech giant is developing its own custom CPU and GPU architectures for a future flagship processor, tentatively dubbed the Exynos 2800. If the rumors hold, this would mark Samsung’s quest for complete hardware independence, mirroring the vertical integration achieved by Apple with its celebrated A-series and M-series chips.
The news, initially surfaced by the prominent leaker Smart Chip Guide on Weibo, suggests that the Exynos 2800 would be the first Samsung System-on-Chip (SoC) to utilize a fully in-house core design, breaking away from licensed ARM CPU blueprints and external GPU partnerships.
According to the detailed report on Weibo, this development represents a pivotal strategic shift for Samsung's semiconductor ambitions.
A Phoenix from the Ashes: Learning from the "Mongoose" Misstep
This venture is not Samsung's first foray into custom CPU design. Between 2016 and 2020, the company invested heavily in its "Mongoose" custom cores, developed by a dedicated team in Austin, Texas. These cores powered several generations of Exynos chips but ultimately faced widespread criticism. Users and reviewers consistently flagged issues with overheating and excessive battery consumption, often resulting in performance and efficiency that lagged behind chips using standard ARM Cortex designs or Qualcomm's optimized Kryo cores.
The project was ultimately shelved around 2020, with the development team disbanded and Samsung reverting to using ARM's off-the-shelf CPU designs—often referred to as "vanilla" ARM cores—for its subsequent Exynos offerings. This retreat was seen as a significant setback for Samsung's dreams of silicon self-reliance.
Why Try Again? Advanced Nodes and "Mature Experience"
So, what's changed? Samsung's management reportedly believes that a combination of "more mature experience" and cutting-edge fabrication technology will provide the foundation for success where Mongoose stumbled. The Exynos 2800 is expected to be manufactured on Samsung's advanced 2-nanometer Gate-All-Around (2nm GAA) process node. This next-generation fabrication technology promises substantial improvements in power efficiency and transistor density, potentially giving Samsung's new design team the thermal and power headroom they previously lacked.
Cutting Ties with AMD: The In-House GPU Vision
The ambition doesn't stop at the CPU. The reports also indicate that Samsung plans to end its graphics partnership with AMD for this flagship chip. Since 2022, high-end Exynos chips have featured AMD's RDNA-based Xclipse GPU, introducing desktop-level gaming features like hardware-accelerated ray tracing to mobile devices.
The Exynos 2800, however, is rumored to feature a completely new, from-the-ground-up GPU designed entirely by Samsung's engineers. This is a critical aspect of the strategy. A custom GPU opens doors for deeper, system-level optimization across Samsung's entire Galaxy ecosystem. From AI processing and machine learning tasks to gaming performance and display management, an in-house GPU allows for tight integration without the constraints of external licensing agreements or architectural compromises.
The Roadmap: Exynos 2600 First, Then the Revolution
Before the fully custom Exynos 2800 sees the light of day, Samsung has another significant release on the horizon. The upcoming Exynos 2600, slated for the Galaxy S26 series, is reported to be the first chip to utilize AMD's next-generation RDNA4 GPU architecture. Interestingly, while it uses the licensed RDNA4 technology, insiders note that the entire GPU implementation and development for the Exynos 2600 was handled internally by Samsung's team, possibly serving as a crucial proving ground for their engineering capabilities.
If development stays on track, the Exynos 2800, with its fully proprietary CPU and GPU, is projected to make its debut in the Galaxy S28 series, expected to launch in 2028.
What This Means for the Market and Consumers
A successful, fully custom Samsung Exynos chip would have profound implications:
- Increased Competition: It would create a third major force in high-performance ARM design alongside Apple's Silicon and Qualcomm's custom Oryon cores, potentially driving faster innovation.
- Galaxy Ecosystem Synergy: Samsung could optimize the chip perfectly for its Galaxy phones, tablets, and wearables, promising a smoother, more efficient, and feature-rich user experience.
- Supply Chain Control: It would reduce Samsung's reliance on external IP licenses, giving it greater control over its product roadmap and cost structure.
The shadow of the Mongoose project looms large, and the industry will watch with cautious optimism. The promise of a fully independent Samsung Exynos chip is tantalizing, but its success hinges entirely on Samsung's ability to deliver where it once fell short: achieving a perfect balance of raw performance, thermal management, and industry-leading efficiency.
