Samsung is reportedly gearing up for full-scale production of the Exynos 2600, a 2nm GAA system-on-chip intended for the upcoming Galaxy S26 lineup. If accurate, this move signals that Samsung Foundry has made tangible progress resolving earlier yield challenges and could finally return Exynos chips to flagship Galaxy models alongside Qualcomm’s Snapdragon variants.
Production and Yield Progress
Reports suggest Samsung’s advanced foundry is transitioning the Exynos 2600 into mass production after earlier teething problems with its 2nm GAA node. Previous estimates put early yields near 30%—low for high-volume smartphone SoCs—but insiders say yields have improved enough to justify a production ramp. Successful mass production would reduce Samsung’s procurement costs and diversify chipset options for the Galaxy S26 family.
Key features of the Exynos 2600
- 2nm GAA process architecture for higher transistor density and efficiency
- Upgraded NPU (neural processing unit) for improved AI and on-device inference
- Competitive CPU/GPU performance suggested by recent Geekbench 6 leaks
- Thermal controls via Heat Pass Block (HPB) to mitigate overheating risks
Thermal management — Heat Pass Block
One long-standing criticism of Exynos SoCs has been thermal throttling in sustained loads. Samsung reportedly integrates a Heat Pass Block (HPB) thermal solution in the Exynos 2600 design to stabilize temperatures and preserve peak performance during gaming and heavy AI tasks.
Comparisons: Exynos 2600 vs Snapdragon 8 Elite Gen 5 and TSMC 2nm
Leaked benchmark runs show Exynos 2600 delivering scores comparable to an underclocked Snapdragon 8 Elite Gen 5, indicating the 2nm GAA node can compete with TSMC’s leading process. TSMC’s 2nm technology is expected to be in mass production in Q4 2025, so Samsung’s 2nm progress puts it in a closer race with industry leaders.
Advantages, Use Cases, and Market Relevance
If mass production holds, benefits include lower sourcing costs for Samsung, more regional chipset diversity for consumers, and stronger on-device AI capabilities for photography, AR, and productivity apps. For enterprise and developer communities, a widely available 2nm GAA SoC accelerates adoption of power-efficient AI workloads on mobile devices.
Takeaway
While the report is encouraging, Samsung still needs to rebuild trust with OEMs and consumers after past overheating and performance inconsistencies. The Exynos 2600’s success will depend on sustained yields, real-world thermal performance via HPB, and how it stacks up against Snapdragon and TSMC-based alternatives in final Galaxy S26 devices.
