Samsung appears to have solved one of the main issues with its flagship Exynos chips: overheating and rapid performance drop under load. In a new test, the Exynos 2600 showed unexpectedly strong thermal management and outperformed the Snapdragon 8 Elite Gen 5, even when Qualcomm's chip was cooled with liquid nitrogen.
The unusual comparison was conducted by YouTube creator Geekerwan. The test used the Exynos 2600 inside the Galaxy S26 and Galaxy S26+ for most markets. For the Snapdragon 8 Elite Gen 5, a separate experimental setup with liquid nitrogen was used, so this isn't a direct comparison of two regular smartphones under equal consumer conditions. Still, the result drew attention due to just how significant Samsung's progress appears to be.
The key factor was the Heat Pass Block technology. In the Exynos 2600, Samsung placed a copper heat spreader directly over the chip die to channel heat away from the hottest areas more quickly. This allowed the processor to maintain better temperature control, while the Snapdragon 8 Elite Gen 5, despite extreme cooling, couldn't keep a single core stable at high frequencies.
That said, the Exynos 2600 isn't completely free of throttling—other factors inside the phone's chassis still affect it. However, the test showed that the problem can be significantly mitigated with a simpler solution, like a small external fan attached to the back of the device. For an average user, that's far more practical than liquid nitrogen experiments.
If the results hold up in independent tests of production units, the Exynos 2600 could be Samsung's most important step in developing its own mobile chips in years. The company has long lagged behind Qualcomm in sustained load stability, but Heat Pass Block indicates that the battle is now not just about peak performance but also about maintaining it during long gaming sessions and other demanding tasks.
Interestingly, Samsung's technology may have already caught Qualcomm's attention. Reports suggest the American company is considering a similar Heat Pass Block solution for the future Snapdragon 8 Elite Gen 6 Pro. If that happens, the Exynos 2600's approach could influence not only Galaxy phones but the next generation of flagship Android chips as a whole.
