Samsung is developing fully custom CPU and GPU designs for the Exynos 2800, marking a return to in-house core architectures after years of relying on ARM and AMD. The chipset, targeting a 2027 launch for the Galaxy S28 series, aims to achieve Apple-level vertical integration.

Exynos 2800 Strategic Details

Component	Current (Exynos 2600)	Future (Exynos 2800)
CPU Cores	ARM v9.3 standard	Custom in-house design
GPU	AMD RDNA 4 (Xclipse 960)	Custom Samsung GPU
Manufacturing	2nm GAA (second-gen)	2nm GAA (third-gen SF2P+)
Expected Launch	Galaxy S26 (2026)	Galaxy S28 (2027-2028)
Development Goal	Reduce Qualcomm reliance	Full hardware autonomy

Return to Custom CPU Development

According to Weibo tipster Smart Chip Guide, Samsung will abandon standard ARM CPU cores for the Exynos 2800, bringing back in-house designs. This isn’t Samsung’s first attempt—between 2016-2020, the company developed “Mongoose” cores at its Austin facility.

However, Mongoose struggled with efficiency and thermal management, often falling behind Qualcomm’s Snapdragon in real-world usage. Samsung disbanded that team in 2020, reverting to standard ARM architectures. The Exynos 990 was the last flagship featuring Mongoose cores.

Custom GPU to Replace AMD Partnership

Beyond CPU independence, Samsung is developing a proprietary GPU to replace AMD’s RDNA architecture, which has powered Exynos flagship chips since the Exynos 2200 in 2022. Even the recently announced Exynos 2600 uses AMD’s RDNA 4-based Xclipse 960 GPU, though Samsung handles most implementation internally.

A custom GPU enables deeper optimization for AI processing, gaming, and Galaxy ecosystem integration without external licensing restrictions. This move mirrors Apple’s integrated silicon strategy, where custom Apple GPU delivers exceptional efficiency.

Strategic Rationale: Cost & Control

Rising Qualcomm Costs: The Snapdragon 8 Elite Gen 5 costs approximately $280 per unit, with Gen 6 projected to exceed $300. These premiums pressure Samsung’s flagship margins significantly.

Qualcomm Agreement: Currently, 75% of Galaxy S26 devices use Snapdragon 8 Elite Gen 5, with Exynos 2600 occupying just 25%. Analyst Samir Khazaka notes: “You don’t pour money into in-house CPU and GPU design for a permanent minority role.”

Long-term Independence: Samsung aims to expand Exynos presence across its smartphone lineup once Qualcomm agreements expire, reducing dependency on external silicon vendors.

Beyond Smartphones: Broader Applications

Samsung’s custom GPU strategy extends beyond mobile devices. With parallel computing advantages, the Exynos 2800 can power:

Smart glasses requiring efficient graphics
Autonomous vehicle systems needing real-time processing
Humanoid robots demanding AI acceleration
AI servers leveraging GPU compute capabilities

This diversification justifies the massive R&D investment beyond smartphone-only applications.

Manufacturing Advantage: 2nm GAA Process

Samsung has completed the basic design of its second-generation 2nm GAA process and plans to implement the third-generation SF2P+ within two years. The Exynos 2800 will likely utilize one of these advanced nodes, providing manufacturing advantages over competitors still on older processes.

Talent Acquisition Strategy

Samsung recently hired John Rayfield, former AMD Vice President with deep graphics expertise, as Senior Vice President at the Advanced Computing Lab (ACL) and Samsung Austin Research Center (SARC). Experienced GPU engineers receive offers between 500 million to 1 billion won ($338,000-690,000), reflecting Samsung’s commitment to building world-class graphics capabilities.

Timeline & Risks

The Exynos 2800 targets a 2027 development completion with potential Galaxy S28 deployment in 2028. This multi-year timeline allows Samsung to refine architectures and avoid Mongoose’s efficiency pitfalls.

However, success isn’t guaranteed. Custom silicon requires sustained investment, top engineering talent, and years of iteration—resources even Apple took decades to perfect.
