Exynos 2700 for Galaxy S27 series is already showing significant performance gains, new leaks suggest

The Galaxy S26 Ultra is said to feature the Exynos 2600 SoC only in South Korea, but rumors about its successor have already started creeping up. The Exynos 2700, expected to power the Galaxy S27 series of flagship smartphones, is shaping up to be a more polished chip with significant performance gains, at least according to a new leak.

For a while now, Samsung has been trying to develop its own mobile SoC to compete with the flagship Qualcomm Snapdragon processors. Initial rumors and benchmarks suggest that the upcoming Exynos 2600 could be the one that stands head-to-head with the top tier Snapdragon 8 Elite Gen 5. Now, a new leak hints at what Samsung has been able to learn from the Exynos 2600 and the performance gains that its next generation Exynos 2700 will reportedly bring.

The information comes from ‘Kaulenda’ on X who doesn’t seem to have an established history of leaks like some other popular leakers. What the leaker does have is alleged key details for the Exynos 2700, codenamed Ulysses. The post includes information about the SoC, along with AI generated images made to look like marketing material. Exynos 2700 is expected to be based on the newer and more efficient SF2P node, compared to the SF2 node which the Exynos 2600 is based on. Thanks to this next generation manufacturing process, the Exynos 2700 will get a claimed 12% performance boost and 25% power reduction. It is also said to reach a higher clock speed of 4.2 GHz - for some of its cores - compared to the 3.8 GHz max for the Exynos 2600. 

As for estimated Geekbench scores, the Exynos 2700 is said to score 40% higher in single-core performance and 30% higher in multi-core compared to the Exynos 2600. It also uses a unified copper Heat Path Block (HPB) in a FOWLP-SbS (Side-by-Side) packaging design, an upgrade over first generation iteration for the Exynos 2600. This brings the DRAM next to the die with the heat sink (HPB) covering both components. Along with the CPU, the next generation Xclipse GPU will get an upgrade as well with around 80% to 100% faster data transfers from the LPDDR6 RAM and UFS 5.0 storage, resulting in up to 40% performance gains.

From the leaks, it seems like the Exynos 2600 has provided a solid foundation for Samsung, but various reports have signaled against wider adoption of the SoC. For now, it seems like only the Galaxy S26 Ultra models within South Korean will feature the in-house chip, and global markets will stick with the Snapdragon 8 Elite Gen 5. It is unclear what plans Samsung has for the Galaxy S27 lineup and if more markets will get to experience Exynos 2700. It could be that the limited launch for the Exynos 2600 powered phones is a trial run for the in-house manufacturing process.
