Samsung’s next premium smartphone may face an awkward hardware dilemma. The Snapdragon 8 Elite Gen 6 Pro, expected to power the Galaxy S27 Ultra, reportedly runs hotter than acceptable limits in internal testing. If Qualcomm cannot tame the thermal issues in time, Samsung could switch to its own Exynos 2700 chipset.
Such a switch would be a notable change for Samsung’s top-tier phone. The company is reportedly pressing Qualcomm for a solution as production preparations move closer, leaving the processor maker with limited time to address the problem.

Galaxy S27 Ultra’s Snapdragon Chip Reportedly Faces Thermal Trouble
According to a report from South Korea’s Seoul Economic Daily, the Snapdragon processor tested inside the Galaxy S27 Ultra has repeatedly exceeded internal temperature limits. The chip reportedly responds by throttling its performance to control heat and prevent potential damage.
Thermal throttling is a familiar challenge in high-performance smartphones. When a processor gets too hot, it reduces its clock speed to bring temperatures back under control. This protects the hardware, though it can also reduce gaming performance and slow demanding workloads.
For the Galaxy S27 Ultra, such behavior could become a serious concern. Samsung is expected to place considerable emphasis on on-device AI features, intensive gaming and other processor-heavy tasks. If the chipset struggles to maintain stable temperatures, users could face inconsistent performance during extended sessions.
A flagship phone can deliver impressive benchmark numbers for a short burst. Keeping that performance steady over time is a different matter entirely.
Qualcomm Reportedly Faces a Mid-October Deadline
Samsung’s Galaxy S27 series is nearing the production-prep stage, with reports suggesting the designs are already finalized. That leaves little room for major hardware changes as the launch schedule nears.
According to the report, Samsung has given Qualcomm until mid-October to resolve the Snapdragon chip’s thermal instability. Engineers from both companies are reportedly working to refine the processor. Still, they have not yet met the required temperature standards.
An industry official reportedly addressed the situation, stating, “It is not as though Qualcomm’s processor has been ruled out for the Galaxy S27 Ultra… But if the overheating issue is never resolved, we have to think about alternatives for mass production.”
The statement suggests that Samsung has not made a final decision. Qualcomm still has an chance to keep its place in the Galaxy S27 Ultra, provided it can deliver a chip that meets Samsung’s thermal requirements.
However, the clock is ticking. If the problem persists, Samsung may have to reconsider its processor plans before mass production begins.
Exynos 2700 Could Become Samsung’s Backup Plan
Samsung reportedly has another option if Qualcomm fails to resolve the issue. The company could equip the Galaxy S27 Ultra with its own Exynos 2700 chipset instead of the Snapdragon processor.
The Exynos 2700 is rumored to power the standard Galaxy S27 and the new Galaxy S27 Pro. If it arrives in the Ultra model, it could mark a substantial shift in Samsung’s flagship strategy.
The chipset is reportedly built using Samsung’s 2nm manufacturing process. Its production yields are also said to be stronger than the Exynos 2600’s, which could make it a more practical choice for large-scale manufacturing.
Manufacturing yield matters because it affects how many working chips a production run can deliver. Better yields can reduce waste and help a company supply enough processors for a major smartphone launch.
Still, a smaller manufacturing process does not automatically guarantee lower temperatures or better performance. Chip design, power consumption, cooling hardware and software optimization all influence how a processor behaves under sustained load.
Samsung would need to ensure that the Exynos 2700 can handle the Galaxy S27 Ultra’s demanding workloads without introducing new performance or efficiency concerns.
First Exynos-Powered Galaxy S Ultra in Five Years?
If Samsung follows through with the reported switch, the Galaxy S27 Ultra could become the first Ultra-tier flagship in five years to use an Exynos processor.
That possibility would revive a familiar debate among Samsung smartphone buyers. Snapdragon and Exynos chips have often drawn comparisons over gaming performance, power efficiency, heat management and battery life.
The outcome would depend on the final hardware and software, rather than the chipset name alone. A well-tuned Exynos 2700 could give Samsung greater control over its supply chain, while a poorly optimized version could raise new questions about the Ultra model’s performance.
There is another factor to consider. Samsung already develops its own processors and manufactures chips, so using Exynos in its most expensive smartphone could give the company more flexibility in production planning.
Even so, switching processors this late in development could require careful adjustments to firmware, power management, and thermal tuning. Samsung would need to ensure the finished device delivers a consistent experience under demanding tasks.
Could Samsung Keep Snapdragon by Reducing Performance?
The Exynos 2700 is not yet confirmed as a replacement. Qualcomm could still fix the reported heating issue, allowing Samsung to keep the Snapdragon chip in the Galaxy S27 Ultra.
One possible solution is to lower the processor’s clock speeds. Underclocking could reduce power consumption and heat output, although it might also limit peak performance.
Samsung could also revise the phone’s cooling system. A larger or more effective vapor chamber could spread heat over a wider area, letting the processor maintain higher performance longer.
Both approaches involve trade-offs. Reducing clock speeds may affect demanding applications, while a more substantial cooling system could require changes to the phone’s internal layout. The final decision would depend on how much heat the processor generates and how effectively the available cooling hardware can dissipate it.
Qualcomm and Samsung may still find a solution that preserves the Snapdragon configuration without compromising the phone’s intended performance.
Galaxy S27 Ultra’s Processor Remains Uncertain
For now, the Galaxy S27 Ultra’s final chipset remains uncertain. Reported thermal problems have put Qualcomm under pressure, but Samsung has not confirmed that it has abandoned Snapdragon.
If Qualcomm resolves the issue, the phone could still launch with the Snapdragon 8 Elite Extreme Gen 6, as the original report described. Otherwise, Samsung may use the Exynos 2700 as its alternative for mass production.
The distinction matters because a processor change can affect more than benchmark results. Heat management, battery endurance, gaming stability, and sustained AI performance all shape how a premium smartphone feels in everyday use.
Samsung’s immediate challenge is choosing a chipset that meets its performance targets without letting temperatures spiral out of control. Qualcomm still has a chance to secure the deal, but the Exynos option gives Samsung another route forward.
Until the company confirms its plans, treat reports of an Exynos-powered Galaxy S27 Ultra as unverified. The coming production decisions will determine whether Samsung sticks with Snapdragon or brings its own silicon back to the top of its flagship range.
