Samsung’s next big foundry bet is coming into clearer focus, and it looks far more encouraging than the company’s rocky start with 3nm. After struggling with 3nm GAA yields reportedly stuck around 30 percent, Samsung watched many fabless chip designers shift their business elsewhere. Now, the spotlight is on 2nm GAA, where Samsung is preparing its first in-house 2nm flagship silicon, the Exynos 2600, and trying to prove it can compete at the cutting edge again.
The reason this matters is simple: advanced manufacturing is all about yields. Even if a process is technically impressive, it won’t be profitable until enough chips come off the wafer in usable condition. And according to a recent investment firm analysis cited by a Korean report, Samsung may still have a lot of work to do if it wants to hit its profitability goals by 2027.
A more cautious view on Samsung’s 2nm GAA progress
Earlier chatter around Samsung’s 2nm GAA process painted an optimistic picture, with talk of around 50 percent yield. That would be a meaningful step forward compared to the company’s 3nm difficulties and would help explain why Samsung has been pushing ahead with plans around Exynos 2600 and broader foundry expansion.
However, KeyBank’s more conservative take suggests the real number could be under 40 percent. If that estimate is accurate, Samsung’s 2nm ramp may be progressing, but not as quickly as many hoped. The gap between “about 50 percent” and “below 40 percent” is huge in semiconductor manufacturing, because it can mean the difference between a viable commercial ramp and a costly, slower climb toward maturity.
Exynos 2600 plans keep momentum alive
Despite the uncertainty around exact yield figures, Samsung appears to be moving forward confidently with Exynos 2600. The chip is reportedly being explored for future foldable phones, including a model in the Galaxy Z Flip lineup. That alone suggests Samsung believes the 2nm GAA effort is on track enough to support major consumer products, where power efficiency, thermals, and supply consistency matter as much as performance.
Samsung also isn’t standing still on the process roadmap. Reports indicate the company is shifting attention toward a second-generation version of its 2nm technology, known as SF2P, with basic design work said to be completed. That’s an important signal because it implies Samsung is already planning refinements for better efficiency and higher yields beyond the first iteration.
Taylor, Texas plant shift points to bigger 2nm ambitions
Another major development is happening in the United States. Samsung’s Taylor facility was originally intended for 4nm production, but it’s now being transitioned toward 2nm wafer manufacturing. EUV tool test operations are expected to begin in March, which is a key step in bringing advanced-node capability to that site.
If executed well, this move could strengthen Samsung’s position as a serious alternative supplier at a time when the market is desperate for leading-edge capacity. Demand for advanced chips remains intense, and supply constraints have reportedly become so extreme that some customers are paying up to a 100 percent premium just to secure production allocation.
That environment could work in Samsung’s favor. Even if yields aren’t perfect yet, customers looking for a second source beyond the dominant supplier may still be motivated to commit—especially when product roadmaps and AI-driven demand leave little room for manufacturing bottlenecks.
The yield debate: conflicting signals and what to watch next
One reason the “below 40 percent” estimate is raising eyebrows is that it doesn’t neatly align with the idea of Samsung winning very large partnerships. If yields were truly that low, it would be harder to justify confidence in scaling production quickly and economically. On the other hand, the earlier reported 50 percent figure for Exynos 2600 manufacturing—mentioned as far back as September 2025—still hasn’t visibly changed as of mid-January, which leaves room for doubt in either direction.
At this point, there are two realistic possibilities: either Samsung’s internal progress hasn’t been accurately reflected in external estimates, or the more conservative assessment is closer to reality. What seems clear is that Samsung is pushing hard to turn 2nm GAA into a turning point after its 3nm challenges.
For consumers and the broader chip industry, the next clues will come from signs of stable mass production, more confirmed customer commitments, and whether Samsung can steadily raise yields to the level needed for strong profitability before 2027.
