Samsung might be getting ready to do something it has never done with its ultimate flagship. While rumors about processor choices usually stay in boardrooms, a secret new prototype equipped with a slightly larger vapor chamber hints that an Exynos 2700-powered Galaxy S27 Ultra is finally possible.
A fresh leak from tech tipster kro reveals that engineers are actively building test units designed with upgraded thermal hardware, specifically tailored to see if in-house silicon can handle the heat.
Redesigning thermals for in-house silicon
Modifying the internal cooling setup on a flagship prototype is a massive undertaking. Historically, the Ultra series has served as an untouchable sanctuary for Qualcomm’s Snapdragon processors worldwide. So, altering the phone’s internal chassis points to serious hands-on testing with the 2nm Exynos 2700.
The new prototype features a slightly larger vapor chamber. This is a key design change aimed at keeping surface temperatures comfortable and preventing performance throttling during intense gaming sessions or heavy 8K video recording. Extra thermal capacity gives the internal silicon room to breathe, which is essential if Samsung wants demanding users to trust an Exynos chip on its top-of-the-line device.
An internal tug-of-war behind closed doors
This hardware development comes amid an ongoing debate between internal Samsung divisions. The System LSI group, which designs the Exynos chip, is making a hard push for the mobile division (MX) to adopt the Exynos 2700 globally across the entire S27 lineup. On the other hand, smartphone executives remain cautious, evaluating long-term thermal efficiency, yields, and production costs before locking in a final supplier decision.
Adding weight to the Exynos argument are early internal benchmark leaks. The Exynos 2700 reportedly scored over 14,000 in Geekbench 6 multi-core tests—roughly a 9.5% lead over Qualcomm’s Snapdragon 8 Elite Extreme Gen 6. While lab benchmarks do not always reflect real-world stability, the tipster noted that for the first time, it looks like Samsung may actually be considering putting an Exynos chip in the Ultra model.
