Samsung is preparing to push its mobile chip ambitions even further with the Exynos 2700, and the biggest story isn’t just faster manufacturing. It’s a major rethink of how the processor, memory, and cooling fit together—an approach designed to deliver higher real-world performance, better power efficiency, and stronger thermal stability during sustained workloads like gaming, 4K video, and on-device AI.
To understand why this matters, it helps to look at what Samsung already changed with the Exynos 2600. That chip introduced a new heat sink concept that improved thermal stability in a meaningful way. Now, Samsung aims to build on that progress with the Exynos 2700 by combining a more refined heat sink with an innovative side-by-side (SBS) memory layout—an upgrade expected to unlock a sizable jump in memory bandwidth.
A key part of the Exynos 2700’s foundation is the manufacturing process. The chip is expected to use Samsung’s SF2P node, described as a next-generation evolution of its 2nm Gate-All-Around (GAA) technology used for the Exynos 2600. GAA is a modern 3D transistor design where the gate wraps around the channel (built from vertically stacked nanosheets) on all sides. The goal is better electrostatic control, improved efficiency, and a lower voltage threshold compared to older transistor structures. In practical terms, SF2P is expected to provide around a 12% improvement in overall performance while cutting energy use by roughly 25% versus the prior SF2 process.
Even with those manufacturing gains, the most meaningful shift for the Exynos 2700 is expected to come from chip layout and packaging. The Exynos 2600 uses a stacked, “sandwich-like” design: RAM sits on top of the system-on-chip (SoC), with a copper-based heat sink element—often referred to as a Heat Path Block (HPB)—positioned above the memory. While that stacked approach can be thermally efficient in some respects, it can also trap heat between the SoC and the RAM, which can impact sustained performance when temperatures rise.
With the Exynos 2700, Samsung is expected to switch to a side-by-side architecture enabled by Fan-out Wafer Level Packaging (FOWLP). Instead of stacking memory on top of the processor, FOWLP would allow Samsung to place the RAM alongside the SoC and integrate both at the wafer level. This change is important because it shortens the interconnects between the processor and memory. Shorter interconnects typically mean faster data transfer and less power wasted moving information back and forth.
As a result, memory bandwidth is estimated to improve by about 30% to 40%, with additional gains possible in power efficiency. That’s a significant uplift for performance areas that lean heavily on memory throughput, including mobile gaming, multitasking, image processing pipelines, and AI workloads that shuffle large datasets.
The thermal benefits could be just as important. With RAM no longer stacked over the SoC, the HPB heat sink can be positioned to better manage heat across the processor and memory arrangement, rather than dealing with a vertical heat pocket. That improved heat flow can translate into more stable performance over time—especially in thin smartphones where cooling headroom is limited and thermal throttling can quickly reduce peak speeds.
The Exynos 2600 has already been described as more thermally stable than Qualcomm’s Snapdragon 8 Elite Gen 5, and Samsung’s planned packaging and cooling changes for the Exynos 2700 suggest the company is aiming to widen that advantage. If these upgrades land as expected, the Exynos 2700 could stand out not only for headline benchmarks, but for the kind of sustained, consistent performance people actually notice day to day.
