Conflicting Rumors Put Exynos 2700’s Packaging Strategy Under the Microscope
Samsung’s upcoming Exynos 2700 chip, expected to power the Galaxy S27 and Galaxy S27+, has become the subject of sharply conflicting reports. One camp claims Samsung will abandon advanced Fan-Out Wafer-Level Packaging (FOWLP) or broader Wafer Level Packaging (WLP) technology as part of a cost-cutting push, even as the company moves the SoC to a second-generation 2nm process. Another report, however, says Samsung intends to give the Exynos 2700 “premium treatment,” keeping its most advanced packaging to better compete with rival flagship processors. At stake is more than manufacturing complexity: packaging choices directly influence heat dissipation, power efficiency, and sustained performance, all critical to Samsung chipset performance in its next wave of premium phones. With rumors pointing in opposite directions, the Exynos 2700 has become a litmus test of whether Samsung prioritizes efficiency and thermals or profitability for its future Galaxy S27 processor.
What FOWLP and WLP Technology Mean for a 2nm Flagship Chip
The debate around the Exynos 2700 centers on whether Samsung will retain FOWLP, a form of advanced WLP technology, for its 2nm packaging technology. FOWLP redistributes electrical connections outside the silicon die, enabling a smaller footprint, thinner package, and denser input/output. Samsung credits this approach, first used on the Exynos 2400, with better thermal management and performance, though it also increases production costs and reduces yields because of added complexity. Keeping FOWLP on a 2nm chip would theoretically allow higher sustained clocks and more consistent performance over long gaming or AI workloads, while also helping limit throttling. Dropping it, by contrast, could simplify manufacturing and improve profitability, but risks undermining one of the core levers for boosting Samsung chipset performance just as it tries to establish the Exynos 2700 as a credible alternative to rival flagship processors inside the Galaxy S27 lineup.
SbS and HPB: Samsung’s Alternative Thermal Design for Exynos 2700
Even as FOWLP’s future is disputed, multiple reports agree that Samsung is preparing a new Side-by-Side (SbS) architecture for the Exynos 2700. Instead of stacking the application processor and DRAM in a package-on-package configuration, SbS places them next to each other on the same substrate. This layout works with Samsung’s Heat Path Block (HPB) technology, which adds a dedicated heat-dissipation layer above the processor and memory. In the Exynos 2600, HPB was used in a stacked layout; for the Exynos 2700, the combination of SbS and HPB is designed to pull heat away from both the CPU and RAM more evenly. If executed well, this could offset some thermal advantages that FOWLP provides, giving the Galaxy S27 processor better sustained performance. The question is whether SbS plus HPB alone can match the efficiency and cooling benefits of a full WLP technology stack on a cutting-edge 2nm chip.
Performance Stakes: Exynos 2700 vs Snapdragon and Dimensity Rivals
The packaging choice for the Exynos 2700 matters because Samsung is not just shrinking transistors; it is also chasing rival chipsets that have set high expectations for flagship phones. Rumors suggest the Exynos 2700 will pair a 10-core CPU with an AMD RDNA 5-based Xclipse 970 GPU, LPDDR6 memory, and UFS 5.0 storage, all on a 2nm process. To translate that specification into real-world gains, Samsung must manage thermals and power tightly or the Galaxy S27 processor risks throttling under sustained gaming, camera, or AI tasks. Maintaining FOWLP within a broader WLP technology approach would give the Exynos 2700 stronger tools to compete with upcoming Snapdragon and Dimensity flagships. A move away from advanced packaging, meanwhile, could reinforce perceptions that Exynos-powered models remain a step behind, even if the raw architecture looks impressive on paper.
Cost-Cutting or Premium Play? What It Means for Galaxy S27 Buyers
Behind the technical arguments is a strategic dilemma: should Samsung optimize the Exynos 2700 for profitability or for maximum performance? Reports claiming FOWLP might be dropped frame the move as a way to control costs after earlier Exynos generations reportedly suffered from lower yields and higher complexity. Opposing leaks argue that Samsung, facing intense competition and scrutiny, plans to keep its best packaging on the Exynos 2700 to raise the competitive bar. Both sides agree that the SoC is central to the Galaxy S27 experience, especially in markets where Exynos variants are sold instead of Snapdragon models. If Samsung sticks with advanced WLP technology and SbS cooling, the Exynos 2700 could signal a genuine reset for Samsung chipset performance. If cost-cutting wins out, Galaxy S27 buyers may again question whether they are getting the most capable silicon in a flagship phone.
