TL; DR
- A South Korean report claims Samsung found the Snapdragon 8 Elite Extreme Gen 6 overheating and throttling during Galaxy S27 Ultra testing, prompting it to ask Qualcomm for a fix by mid-October.
- Qualcomm has denied the claims through both its CMO Don McGuire, who called the reports “100% NOT accurate,” and its official Snapdragon account, which also described the reporting as inaccurate.
- Samsung could reportedly turn to its Exynos 2700 if the issue remains unresolved.
Qualcomm has publicly denied reports that its Snapdragon 8 Elite Extreme Gen 6 is overheating during Samsung’s internal testing for the Galaxy S27 Ultra. Both Qualcomm’s chief marketing officer and the official Snapdragon account have rejected the claims, following a report that Samsung could switch to its own Exynos 2700 chip if Qualcomm fails to address the alleged thermal issues.
Qualcomm responds to overheating reports
The original report from South Korea’s Seoul Economic Daily, citing unnamed industry sources, claimed Samsung’s internal testing found the Snapdragon 8 Elite Extreme Gen 6 exceeding temperature limits under sustained workloads. The chip reportedly throttled as temperatures rose, raising concerns about its ability to maintain performance during demanding tasks.
According to the report, Samsung asked Qualcomm to resolve the issue by mid-October before finalizing the processor for the Galaxy S27 Ultra. It also claimed the Exynos 2700 performed adequately in comparison and could become the fallback option if the reported Snapdragon problems persisted.
Qualcomm CMO Don McGuire responded on X, calling the reports “100% NOT accurate.” He also explained that smartphone manufacturers routinely tune chipsets to balance performance and power consumption across different workloads, with Qualcomm working closely with its partners on their final products.
The official Snapdragon account also addressed the reports directly. In a separate post, it stated, “Recent reporting about thermal issues related to Snapdragon 8 Elite Extreme Gen 6 is inaccurate.” The company added that it remains confident in its next-generation flagship platform and continues to work with global smartphone manufacturers.
Snapdragon 8 Elite Extreme Gen 6’s sustained performance remains a question
The report centers on thermal performance under prolonged workloads, rather than necessarily suggesting the chip has problems during everyday use. High-performance smartphone processors can reduce their clock speeds to control temperatures during extended gaming, benchmarking, and other demanding tasks.
The Snapdragon 8 Elite Extreme Gen 6 is reportedly clocked close to 5GHz on its prime cores. Cooling will therefore be an important factor in how well it maintains peak performance, particularly during sustained workloads. Some gaming phones using the chip pair it with large vapor chambers or active cooling systems (RedMagic 12 Pro).
Could Samsung use the Exynos 2700 in the Galaxy S27 Ultra?
Samsung has relied exclusively on Snapdragon processors in its Ultra models for several years. Using the Exynos 2700 in the Galaxy S27 Ultra would mark a significant change, although it’s not yet confirmed that it is considering a switch.
The mid-October deadline mentioned in the original report has passed, but Qualcomm’s responses and confidence suggests the issue has been resolved. The Galaxy S27 series is expected to arrive in the usual January or February window in early 2027.
