Qualcomm has denied reports that its Snapdragon 8 Elite Extreme Gen 6 chipset suffers from serious overheating and thermal throttling. The response follows claims that Samsung is considering an all-Exynos strategy for the Galaxy S27 Ultra after internal testing allegedly showed better thermal performance from the Exynos 2700.

Qualcomm’s chief marketing officer addressed the reports in a response to a thread on X. The executive said recent coverage of thermal problems affecting the Snapdragon platform was inaccurate and added that Qualcomm remains confident in the technology behind its next flagship chip.

Qualcomm says there are no systemic thermal issues

According to Qualcomm’s statement, the Snapdragon 8 Elite Extreme Gen 6 does not have systemic thermal problems. The company said it is working with smartphone manufacturers to deliver premium experiences as its next-generation platform moves toward commercial devices.

The response also questioned whether alleged findings from Samsung’s internal testing accurately represent the chipset’s behavior. Qualcomm said device makers tune their platforms for different balances between performance and power consumption, depending on the intended use cases. As a result, results from one company’s testing environment may not reflect the final behavior of another manufacturer’s phone.

Qualcomm did not provide independent test figures or specific details about the reports it was disputing. The company’s comments therefore reject the broader overheating claim but do not establish how the chipset will perform in retail devices.

Galaxy S27 Ultra Exynos rumors remain unconfirmed

The original report claimed that Samsung was evaluating an all-Exynos approach for next year’s Galaxy S27 Ultra. It attributed that possibility to internal comparisons in which the Exynos 2700 reportedly avoided the thermal throttling seen with Qualcomm’s chip.

Neither Samsung’s alleged testing results nor a decision about the Galaxy S27 Ultra’s processor lineup has been confirmed in the available information. Qualcomm’s denial adds a direct response from the chipmaker, but it does not confirm which processor variants Samsung may ultimately use.

Why sustained performance matters for smartphone chips

The dispute comes as mobile processors continue to push toward performance levels associated with PCs and gaming systems. The current Snapdragon 8 Elite Gen 6 series is described as using two Prime cores running at 5.0GHz and six Performance cores running at 4.0GHz.

Those clock speeds can place substantial demands on a smartphone’s passive cooling system. High peak performance does not necessarily mean a phone will become uncomfortably hot during everyday use, but extended workloads can expose limits through reduced sustained performance.

Stress testing of recent flagship phones has shown noticeable performance drops over time, according to the report. That behavior is generally linked to thermal management rather than proof of dangerous overheating. Qualcomm’s statement means real-world testing of finished devices will be important in determining whether the Snapdragon 8 Elite Extreme Gen 6 delivers strong performance without excessive throttling.
