Samsung may be putting an in-house chip back into its top-end phone. According to a report GSMArena covered on October 16, the Galaxy S27 Ultra could return to the Exynos 2700, which reportedly beat the Snapdragon 8 Elite Extreme Gen 6 by about 10% in Geekbench multi-core in internal testing. Treat it as a rumor for now.
Exynos 2700 vs Snapdragon: what the leaks claim

The most detailed figures come from a Korean Sedaily report dated August 23, cited by PhoneArena and Notebookcheck. In a Samsung in-house Geekbench 6.5 test, the Exynos 2700 allegedly scored 19% higher multi-core than the Snapdragon 8 Elite Gen 6 and 9.5% above the Pro version.
- GPU: about 5% ahead of the Pro Snapdragon.
- AI: 18% faster responses with the Llama 3.1 8B model.
- Power draw: 12.7% lower in Samsung’s own tests, per Notebookcheck.
What we know about the chip
Notebookcheck spotted a test system (S5E9975 ERD) whose prime core reaches up to 4.24 GHz, against about 2.88 GHz in April. The chip reportedly has ten cores in four clusters and is built on a 2nm process (SF2P). A Geekbench identifier points to ARM C2 Ultra cores, which remains unconfirmed.
Why caution is warranted

Notebookcheck points out that Sedaily has published flattering internal Exynos results nearly every year, and independent tests have rarely reproduced them. The test was run by Samsung itself, and the 4.24 GHz figure comes from a development board rather than a retail phone. Chip assignments for the Galaxy S27 lineup are not confirmed.
What it would change for you
Until now the Ultra was expected to use a Snapdragon worldwide. Samsung has said it wants Exynos chips in every Galaxy, Ultra included. If the rumor holds, top performance would no longer be a Qualcomm-only selling point, and regional differences would fade. The Galaxy S26 already paved the way with the Exynos 2600, described as the first 2nm phone chip.
For now, the takeaway is simple: the Exynos 2700 looks good on paper, but only independent tests on a retail device will settle it. Exynos or Snapdragon in your next Ultra? Tell us below.
