Samsung’s next Exynos step appears to be less about chasing raw speed and more about fixing the weaknesses that have followed the chipset line for years. The rumored Exynos 2700, expected to arrive with the Galaxy S27, is being positioned as a more serious answer to heat and power efficiency.
That matters because Samsung has only recently started to show real progress on the Exynos side. The Exynos 2600, which is expected to appear in the Galaxy S26, is said to be the first recent chip in the family that feels closer to flagship standards, even if it still does not fully match Snapdragon at the top end.
A new layout aimed at heat control
The biggest change tied to Exynos 2700 is a new SBS design. According to a report cited by SamMobile, this approach places the memory beside the SoC instead of stacking it on top of the chip as in previous designs.
That shift is meant to improve heat dissipation. With the memory no longer sitting above the SoC, the chip is less likely to run into thermal buildup, which should make temperature management more stable under pressure.
The layout may also help in another way. Shorter signal paths could reduce latency, and that can improve overall performance beyond the cooling benefit alone.
If thermal conditions are better controlled, Samsung would also have more room to raise clock speeds. That opens the door for higher performance without hitting heat limits as quickly as before.
What Exynos 2600 already changed
Before Exynos 2700 became part of the conversation, Samsung had already introduced a different thermal approach in Exynos 2600. That chip uses a Heat Path Block, which integrates a heat sink directly into the chip to help move heat away faster.
Samsung says that solution reduces thermal resistance by 16%. The goal is straightforward: push heat away from the chip more efficiently so operating temperatures stay steadier in real-world use.
This appears to be paying off in daily use. Exynos 2600 is reported to run less hot than earlier Exynos generations, which had long been one of Samsung’s biggest weaknesses in its own flagship chips.
Even so, the gap is still there. Qualcomm’s Snapdragon 8 Elite Gen 5, used in the Galaxy S26 Ultra, is still described as clearly ahead in both performance and thermal behavior.
Why Samsung is still splitting its flagship lineup
The difference between Exynos and Snapdragon remains noticeable in practical use. Battery life is one of the clearest signs, with testing said to show Snapdragon with a strong lead over Exynos.
That is also reflected in Samsung’s Galaxy S26 strategy. Exynos 2600 is used in the base and Plus models, while the Galaxy S26 Ultra uses Snapdragon 8 Elite Gen 5 exclusively in all markets.
At the same time, Snapdragon versions of non-Ultra models are only available in certain markets. That split shows Samsung is still not fully comfortable making Exynos the sole engine for its flagship range.
A crucial test for Exynos’ future
For years, Exynos has struggled to deliver a truly top-tier flagship experience. Heat and efficiency problems repeatedly kept it behind rivals, especially Qualcomm.
The progress seen with Exynos 2600 suggests Samsung is moving in a better direction, but it still looks like an early step rather than a final fix. That is why Exynos 2700 carries so much weight.
If the SBS design works as intended, Samsung could gain better cooling, lower latency, and more headroom for higher clock speeds. That would make Exynos 2700 one of the most meaningful upgrades the line has seen in years and could help Samsung narrow the gap with Snapdragon in sustained performance and efficiency.
