Galaxy S26's Exynos 2600 Chip Boasts Better Heat Management

Galaxy S26’s Exynos 2600 Chip Could Have Better Heat Management

Samsung’s Exynos chips are infamous for poor efficiency and heat management. However, the company is now developing new technologies to overcome these challenges. The Exynos 2600 chip, expected in some Galaxy S26 models, could benefit from a significant cooling upgrade.

According to ZDNet Korea, Samsung plans to implement Heat Pass Block (HPB)—a thermal management technology—to enhance the performance and cooling of its Exynos 2600 chip. This could solve one of the major complaints long associated with Exynos processors.

What is HPB?

Heat Pass Block (HPB) is a copper-based heatsink solution placed inside the chip package itself. It helps dissipate heat from the CPU, GPU, RAM, and other components. HPB sits directly on top of the application processor and DRAM, drawing heat away from the silicon to keep it running cooler and more efficiently.

The Exynos 2600 is built using Samsung’s 2nm fabrication process through its System LSI division and Samsung Foundry. It will be the first Exynos processor to feature HPB technology.

Progress and Production Timeline

Samsung reportedly expects to complete testing of the Exynos 2600 by October 2025. If successful, the chip will enter mass production for launch in the Galaxy S26 series by early 2026.

The Galaxy S26 Ultra, however, is rumored to continue using Qualcomm’s Snapdragon 8 Gen 2 Elite, maintaining the trend of mixed chip usage across Samsung’s flagship lineup.

Evolution in Packaging Technology

This isn’t Samsung’s first innovation in chip packaging. The Exynos 2400 used Fan-Out Wafer Level Packaging (FOWLP), which separates I/O terminals from the main chip body to improve heat dissipation. The Exynos 2600 also continues this with FOWLP, showing Samsung’s long-term commitment to thermal improvements.

With the addition of HPB, Samsung may finally begin closing the performance and efficiency gap between Exynos and Snapdragon chips.
