A Qualcomm Snapdragon 8 Elite Gen 6 Pro chip, built on a 2nm process, has briefly appeared on the Chinese second-hand platform Xianyu, revealing new technical details ahead of its expected 2025 launch.
First Engineering Samples and Packaging Details
The leaked images show two Snapdragon 8 Elite Gen 6 Pro engineering samples (ES) marked with the code SM8975-100-BC. These early samples support LPDDR5X memory and feature batch numbers revealing their assembly timeline.
One chip carries the batch code FC5528M5, indicating assembly at Amkor’s South Korea factory using TSMC’s 2nm process (likely N2P) in late December 2025 (week 52). The second has the code FX602R8T, suggesting packaging around the second week of 2026.
Samsung-Inspired HPB Heat Dissipation
Notably, the images showcase a new heat dissipation design inside the chip packaging. Qualcomm appears to adopt a cooling block similar to Samsung’s “HPB” (Heat Pipe Block) used in the Exynos 2600. This block sits between the chip die and the package lid, improving thermal management.
This marks the first visual confirmation of Qualcomm applying a Samsung-style internal heat dissipation method at the chip packaging level to handle the thermal load of this advanced chip.
Memory Support and Packaging Size
Qualcomm’s Snapdragon 8 Elite Gen 6 Pro supports both LPDDR6 and LPDDR5X memory standards. The LPDDR6 variant uses a larger 1295-ball FBGA package, while the LPDDR5X version fits into a 496-ball FBGA package.
Both package types offer less physical space on the chip’s surface for the heat dissipation block compared to Samsung’s Exynos 2600, which uses a smaller 563-ball FBGA package for LPDDR5X memory.
What This Means for Upcoming Flagships
This leak confirms Qualcomm’s advancement towards extreme power efficiency and better thermal solutions for next-generation flagship SoCs. The combination of 2nm process technology and upgraded cooling could enhance performance and stability for future devices, including models from Xiaomi and other Android manufacturers expected to adopt this chip.
The Snapdragon 8 Elite Gen 6 Pro is positioned as the most powerful Android chip available around late 2025 and early 2026, with Xiaomi devices likely among the first to feature it.
For users tracking Xiaomi’s update path and hardware launches, this chip’s progress points to considerable performance gains under the Xiaomi HyperOS ecosystem.
This leak builds on earlier reports about Qualcomm’s Snapdragon 8 Elite Gen 6 series revealed at the Qualcomm Summit, which confirmed the 2nm fabrication process and hinted at strong performance improvements. Those reports also highlighted broader chipset families, but this is the first detailed look at the Pro variant’s packaging and cooling design.
