Still don't trust Exynos? You may want to watch this video

When Samsung unveiled its latest premium smartphone chip, the Exynos 2600, a few weeks ago, it highlighted HPB. It's a new industry-first technology meant to help the Exynos 2600 chip cool faster. Now, there’s a video showing how it works.

HPB stands for Heat Path Block, and Samsung says it can lower the Exynos 2600’s thermal resistance by up to 16% compared to the Exynos 2500 SoC.

The short YouTube video puts HPB in the spotlight and claims it “liberates the limits of dimensions.” According to Samsung, the technology enables further miniaturization while improving thermal management for higher performance.

In practical terms, Heat Path Block appears to act as an additional heat transfer layer between the die and the vapor chamber or whatever heat spreader the Exynos 2600 ends up using on a phone-by-phone basis.

All in all, the Exynos 2600 should be better suited for gaming and other demanding sustained workloads. HPB is designed to improve sustained performance, something mobile gamers tend to care about most.

Beyond HPB, the video also highlights the Exynos 2600’s structure and a few other design elements:

The Exynos 2600 is expected to debut in at least some Galaxy S26 variants, depending on the region. Samsung is expected to unveil the Galaxy S26 series next month.

Exynos chips don’t have the best reputation due to past missteps, but Samsung seems more confident than usual in the 2600. Whether that confidence is justified remains to be seen. Either way, we’ll put the Galaxy S26 lineup through its paces as soon as it becomes available.
