Qualcomm Reportedly Integrating Samsung’s Heat Path Block Technology in Next-Gen Snapdragon Chipsets
As the holiday season of 2025 approached, industry rumors began circulating about major smartphone chip manufacturers exploring Samsung’s innovative “Heat Path Block” (HPB) technology. By mid-January, the reputable Fixed-focus digital cameras Weibo account suggested that HPB was being considered by several companies known for producing Android-compatible chipsets.
Today, newly leaked schematics for the “SM8975” packaging have surfaced, strongly indicating that Qualcomm is preparing to incorporate Samsung’s HPB design into its upcoming Snapdragon mobile processors. The latest leak, again highlighted by Fixed-focus digital cameras, points to the anticipated Snapdragon 8 Elite Gen 6 Pro model utilizing this advanced heatsink technology—originally developed for Samsung’s soon-to-be-released Exynos 2600 System-on-Chip (SoC).
Addressing Thermal Challenges in High-Performance Mobile Processors
Recent reports have suggested that Qualcomm is adopting the HPB design from its long-standing competitor, Samsung. While Qualcomm’s flagship processors have consistently achieved impressive benchmark scores, they have also faced significant thermal management challenges. Even with the integration of high-end vapor chamber cooling systems, these powerful chips have approached their thermal limits, potentially impacting sustained performance.
Samsung Foundry’s Heat Path Block technology offers a novel approach to thermal management. The HPB is strategically placed directly over the chipset die, ensuring optimal heat dissipation without interference from a DRAM layer. Instead, the DRAM is repositioned to the side, allowing for more efficient cooling and improved processor stability under heavy workloads.
Industry-Wide Interest in HPB Technology
Late 2024 reports identified Qualcomm and Apple as leading external candidates for adopting Samsung’s HPB solution, following Samsung’s pioneering use of the technology in its 2-nanometer Exynos 2600 application processor. As the mobile industry continues to push the boundaries of performance and efficiency, advanced thermal management solutions like HPB are becoming increasingly critical for next-generation chipsets.
The integration of Samsung’s Heat Path Block by major players such as Qualcomm signals a significant shift in mobile processor design, with a clear focus on overcoming thermal limitations and delivering enhanced user experiences in future flagship smartphones.
