In mid-October, Korea’s Seoul Economic Daily reported that the Snapdragon 8 Elite Extreme Gen 6 went past Samsung’s temperature limits during sustained heavy workloads and slowed itself down. That slowdown is called thermal throttling: a chip cuts its speed to protect itself when it gets too hot.
According to that report, Samsung asked Qualcomm in September to fix the chip’s heat behavior by mid-October. As of October 16, the chip still hadn’t met Samsung’s stability target, though the two companies were continuing to tune and retest it. The issue concerns long sessions, like extended gaming, heavy camera use or demanding on-device AI tasks, rather than short benchmark bursts. For a top-priced phone, holding steady speed over a long session matters as much as raw peak power, and some rival phone makers have added active cooling to deal with the same kind of heat.
Samsung hasn’t confirmed the problem, and the Snapdragon chip hasn’t been ruled out. But it puts a clock on the decision, because Samsung needs to lock its chip choice before mass production of the S27 series begins.
