Samsung Introduces ‘Heat Pass Block’ Technology in Exynos 2600 for Enhanced Thermal Transfer, Overheating Prevention, and Improved Efficiency

The upcoming Exynos 2600, currently undergoing prototype production, is set to mark a significant advance in performance and efficiency for Samsung’s flagship system-on-chip (SoC).Utilizing a cutting-edge 2nm Gate-All-Around (GAA) process, the Exynos 2600 aims to enhance processing capabilities. However, past iterations of the Exynos series struggled with thermal management, often experiencing overheating issues despite incorporating vapor chamber technology in smartphones. To counteract this challenge, Samsung plans to integrate an innovative solution known as ‘Heat Pass Block’ (HPB) to optimize heat dissipation, thereby ensuring the SoC maintains peak performance.

How HPB Enhances Thermal Regulation for the Exynos 2600

Traditionally, Samsung’s Exynos chipsets featured DRAM situated directly atop the SoC. Recent reports from ETNews indicate that the design for the Exynos 2600 will evolve, positioning the HPB and DRAM directly on the chip itself. This strategic placement allows the HPB to effectively function as a heatsink, significantly improving heat transfer. Furthermore, Samsung is expected to adopt Fan-out Wafer Level Packaging (FOWLP) in this new architecture, which initially debuted with the Exynos 2400. This enhancement is anticipated to bolster heat resistance and elevate multi-core processing performance.

As a proactive measure against competitors like the Snapdragon 8 Elite Gen 2 and the Dimensity 9500, Samsung aims to ensure that the Exynos 2600 remains competitive. A recent Geekbench 6 leak has revealed that the Exynos 2600 will feature a peak core clock of 3.55GHz, which currently trails behind the Cortex-X925 in the Dimensity 9400+.

The dual integration of HPB and FOWLP is expected to empower the Exynos 2600 to achieve higher operational frequencies. This is crucial for enhancing both single-core and multi-core performance while effectively managing temperatures. As we know, excessive heat can degrade performance, resulting in not only discomfort for users but also potential battery strain and safety concerns, including the risk of battery failure.

If Samsung’s 2nm GAA process achieves favorable yield rates, we could see the official unveiling of the Exynos 2600 by year-end. This timing would coincide perfectly with the anticipated announcement of the Galaxy S26 family, scheduled for early 2026.
