Unreleased Snapdragon 8 Elite Gen 6 Pro Listed for Sale

Qualcomm Snapdragon 8 Elite Gen 6 Pro (SM8975-100-BC) is an unreleased flagship mobile chipset that appeared for sale on Xianyu, China's largest secondhand marketplace, ahead of its expected debut at the Snapdragon Summit. The listing, which was promptly taken down, revealed critical details about the chip's manufacturing process and thermal design, including its production at TSMC's N2P node and a new heat spreader component designed to manage thermal output.

Key Facts

The following table summarizes the confirmed and reported specifications of the unreleased Snapdragon 8 Elite Gen 6 Pro chipset as revealed by the marketplace listing and subsequent analysis.

The unreleased Snapdragon 8 Elite Gen 6 Pro was listed for sale on Xianyu for CNY300 (~RM180) before being taken down.

What Is the Snapdragon 8 Elite Gen 6 Pro?

The Snapdragon 8 Elite Gen 6 Pro is the successor to Qualcomm's Snapdragon 8 Elite Gen 5 chipset, expected to be unveiled at the Snapdragon Summit next month. It is a high-end flagship silicon from Qualcomm designed for mobile devices, and it is the higher-end chip among the two "8 Elite" chipsets the company has teased.

The chipset solves the problem of advanced mobile processing and connectivity, aiming to deliver top-tier performance for smartphones. The leak offers an early look at the chip's manufacturing, showing a 1,295-ball FBGA package for LPDDR6 and a 496-ball FBGA package for LPDDR5X.

What Did the Xianyu Listing Reveal?

The Xianyu listing posted by a seller from Shenzhen described the two items as a desoldered engineering sample taken from a test board. The listing was marked for repair and chip rework, with bulk stock supposedly available. The alleged Snapdragon chip had a placeholder price of CNY300 (~RM180), with the real price open to negotiations.

The listing was promptly taken down but not before details were shared online. The SM8975 designation, which was laser-etched on the chip, matches what was previously linked to Qualcomm's higher-end flagship silicon for this generation. The company has previously teased it will be unveiling two "8 Elite" chipsets ahead of its September debut.

Qualcomm's unreleased flagship chipset surfaced in a Shenzhen secondhand listing marked for repair, with real price open to negotiations.

What Do the Lot Codes Reveal About the Chip's Packaging?

The lot codes on packaged chips typically encode the fab, assembly site, and packaging date. According to Notebookcheck, the "F" identifies TSMC as the fab, likely with its N2P node. The "C" indicates that it was packaged at Amkor's Korea site. The "5" marks 2025, while the "52" indicates workweek 52, meaning it was packaged around late December 2025.

As for the second code, it follows a similar pattern. The chip was made at TSMC, but it was packaged in Amkor's Japan site (thanks to the "X" identifier). Because of the "6" and "02" marks, the item was packaged in January 2026. The remaining characters are just lot serial numbers.

The lot code analysis reveals that the Snapdragon 8 Elite Gen 6 Pro engineering sample was fabricated by TSMC and packaged at Amkor's facilities in either Korea or Japan.

What Is the "Heat Slug Sheet"?

The "Heat Slug Sheet" is an internal heat spreader that is placed between the die and the package lid. It appears to be Qualcomm's response to Samsung's Heat Pass Block on the Exynos 2600, as revealed by the images in the leaked listing.

The heat spreader appears to be smaller than its Samsung counterparts. Notebookcheck believes this is the case because Qualcomm's chips have to support both LPDDR6 and LPDDR5X, which push toward larger FBGA packages, both of which leave less physical space on the package for the heat spreader.

The "Heat Slug Sheet" is a physical heat spreader in the Snapdragon 8 Elite Gen 6 Pro, a design element that Notebookcheck attributes to Qualcomm's response to Samsung's Exynos 2600 thermal design.

How It Compares: Qualcomm vs. Samsung Thermal Design

The leaked chip's thermal design is a direct point of comparison with Samsung's Exynos 2600. Both chips use an internal heat spreader to manage thermal output, but the solution from Qualcomm appears to have a different design.

The Snapdragon 8 Elite Gen 6 Pro's heat spreader is smaller than Samsung's due to the physical space taken by the larger FBGA packages required for LPDDR6 and LPDDR5X support.
