Samsung Exynos 2700: What Is Known About the 2nm Chip for the Galaxy S27

The Samsung Exynos 2700 is the company’s next flagship mobile processor after the Exynos 2600. Samsung has already confirmed that it is developing the chip for high-end smartphones, and reports on October 2 indicated that mass production had begun. Its production debut is expected in the Galaxy S27 lineup in early 2027.

The Exynos 2700 carries the S5E9975 designation. Test platforms featuring the chip have already appeared in the public Geekbench database, so some of its configuration is known from more than just early leaks.

CPU: 10 Cores and Up to 4.24 GHz

A late engineering sample of the S5E9975 uses 10 CPU cores divided into four groups. According to preliminary data, these are next-generation Arm C2 Ultra and C2 Pro cores:

• 1× Arm C2 Ultra at up to 4.24 GHz
• 4× Arm C2 Pro at up to 3.74 GHz
• 1× Arm C2 Ultra at up to 3.36 GHz
• 4× Arm C2 Pro at up to 2.88 GHz

The frequencies and cluster configuration are confirmed by public Geekbench AI data, although Samsung has not yet officially disclosed the C2 Ultra and C2 Pro names.

The CPU configuration has also changed compared with the Exynos 2600. The Exynos 2700 has two C2 Ultra cores running at different frequencies, whereas its predecessor used a single highest-performance core.

Geekbench 6

The Exynos 2700 currently has two substantially different sets of results.

The public Exynos 2700 result was obtained in Geekbench 6.6.0 on an early sample whose core frequencies were approximately in the 2.30-2.88 GHz range. Therefore, its 2,603 / 10,350 scores do not reflect the capabilities of a later version of the processor.

The 4,328 / 14,700 result belongs to a later engineering sample running Geekbench 6.7.1. These figures appeared in an internal test list and then circulated among specialist publications, but there is still no corresponding public entry in the Geekbench database.

The 4,328 / 14,700 result should therefore be regarded as a preliminary reference point rather than a confirmed result for a production Galaxy S27.

Xclipse 970

Graphics are handled by the Samsung Xclipse 970. The GPU has already been identified under this name in public Geekbench tests.

One engineering sample recorded:

• 8 compute blocks according to Geekbench
• a frequency of up to 720 MHz
• 17,644 points in Geekbench 6 OpenCL

This is an early configuration with a relatively low GPU frequency, so the result cannot be extrapolated to the production version of the Xclipse 970.

Die leaks also point to eight WGP graphics blocks. The Xclipse 970 is sometimes credited with 16 Compute Units on that basis, but this interpretation depends on the internal organization of the new graphics architecture and has not yet been confirmed by Samsung.

There are currently no reliable Exynos 2700 results in 3DMark Wild Life Extreme, Solar Bay, or Steel Nomad Light. It is therefore too early to assess the Xclipse 970’s gaming performance based on calculated or assumed values.

Second-Generation 2nm Process

The Exynos 2700 is associated with Samsung Foundry SF2P, the company’s second-generation 2nm GAA process.

On October 2, the Korean publication The Bell reported that Samsung had begun mass production of the Exynos 2700. According to the publication, it is the company’s first mass-produced product based on the second generation of the SF2P 2nm process.

Samsung has not separately published a detailed technical announcement for the Exynos 2700, so the power consumption and final specifications of the production chip remain unknown.

New Packaging and Cooling

According to preliminary data, the processor and RAM are placed next to each other on a single substrate, with a shared Heat Path Block on top.

This design should simplify heat dissipation from the SoC and DRAM. Its real cooling efficiency can be assessed only after production Galaxy S27 devices and extended load tests become available.

LPDDR6 and Increased Cache

According to preliminary data, the Exynos 2700 is designed to support LPDDR6 memory. Samsung has already prepared LPDDR6 for a new generation of mobile devices, but the full specifications of the Exynos 2700’s memory controller have not yet been published.

An analysis of an alleged die photograph points to approximately 24 MB of SLC system cache and 16 MB of L3 cache. That amounts to about 40 MB of cache, excluding the local caches of the individual CPU cores, GPU, and NPU.

These figures should still be considered preliminary, since Samsung has not yet presented an official Exynos 2700 block diagram.

Which Smartphones Will Get the Exynos 2700

Samsung has already stated that the Exynos 2700 is being developed for high-end smartphones.

The Galaxy S27 series remains the primary candidate. Recent reports link the processor primarily to the Galaxy S27 and S27+, while some sources also suggest that it could be used in the higher-end models in the family.

The allocation of Exynos and Snapdragon chips between specific Galaxy S27 models and regions has not yet been officially announced.

Conclusion

By October 2026, the Exynos 2700 had already moved beyond the early engineering-project stage. Samsung has confirmed its development, S5E9975 test platforms have appeared in the public Geekbench database, a later sample runs at up to 4.24 GHz, and recent reports point to the start of mass production.

At the same time, there is still no definitive performance assessment. The 4,328 / 14,700 Geekbench 6 result comes from an unpublished engineering test, while the publicly available CPU benchmark was obtained on a significantly earlier, lower-frequency sample.

The situation is even less certain for the Xclipse 970: the GPU has already appeared in Geekbench OpenCL, but there are still no real 3DMark or gaming test results. The main questions ahead of the Galaxy S27 launch are the performance of the production CPU, the speed of the Xclipse 970, power consumption, and frequency stability under sustained loads.
