A new leak attributed to @LaidBackDev_ shows what would be a real unit of the upcoming Snapdragon 8 Elite Gen 6 Pro and points to a significant change in the packaging of Qualcomm’s next SoC. The image suggests the DRAM would no longer sit directly on top of the processor, as in Package-on-Package (PoP) designs, and would instead move to the side to make room for a Heat Pass Block (HPB) thermal solution. Qualcomm has not yet officially confirmed either the design or the specs of the chip.
Snapdragon 8 Elite Gen 6 Pro in 20 seconds
- A leak shows what would be the real packaging of the Snapdragon 8 Elite Gen 6 Pro.
- The design points to separating the DRAM from the processor and improving heat transfer with a Heat Pass Block.
- The SM8975 identifier resurfaces in connection with the upcoming SoC.
- The chip is linked to TSMC’s 2nm N2P process, with production planned for the second half of 2026.
- The priority appears to be shifting from peak performance toward sustained frequencies over longer periods.
The main news here isn’t a new frequency or a benchmark number. It’s the chip’s physical shape.
The leaked image shows a package that appears considerably larger than the ones used in previous generations. That doesn’t necessarily mean the logic silicon itself has grown by the same proportion. Part of the extra size would be related to a different memory layout and to the structure designed to pull heat away from the processor.
This possibility had already surfaced months earlier in leaked Snapdragon 8 Elite Gen 6 Pro diagrams. Those images placed a heat-transfer element on top of the SoC and pointed to an architecture similar to the one Samsung has developed around the Exynos 2600.
The photo published now would be the first physical evidence that matches that earlier information, although it remains a leak unconfirmed by Qualcomm.
Moving the DRAM off the top can change a lot more than the size
Smartphone processors typically use extremely compact packaging techniques because space inside the device is limited.
One of them is Package-on-Package. Memory is mounted on top of the processor, which saves board space and shortens certain connections.
The downside shows up when power draw increases.
Placing memory directly on top of the SoC makes it harder for heat to reach the upper layers of the cooling system. In chips capable of hitting increasingly higher frequencies, thermal performance is becoming as much of a limiting factor as the manufacturing process itself.
The solution shown in the Gen 6 Pro leaks would follow a different approach.
The DRAM would shift to one side of the package, freeing up the top of the processor for a piece designed to transfer heat more efficiently to the vapor chamber or thermal solution used by the phone maker.
If confirmed, this would be a significant change.
The goal wouldn’t necessarily be lower temperatures alone. The real benefit could lie in keeping high CPU and GPU frequencies for longer before thermal throttling kicks in.
That behavior matters especially under sustained loads such as gaming, emulation, video recording, heavy photo processing, or running AI models locally.
A processor can post an extraordinary score during the first few minutes of a test and then throttle down once it hits its thermal limit.
Improving heat transfer targets exactly that gap between peak performance and sustained performance.
Heat Pass Block keeps showing up alongside the next-generation Snapdragon
The Heat Pass Block concept has been showing up in leaks tied to the next Snapdragon for months.
In February, several sources published a diagram attributed to the future Snapdragon 8 Elite Gen 6 Pro that already showed a structure of this kind. The information originally came from Chinese leakers rather than Qualcomm, so it couldn’t be confirmed at the time either.
The approach resembles the thermal solution associated with Samsung’s Exynos 2600.
The idea is to place a conductive layer or block directly over the chip’s hot spot to reduce thermal resistance between the silicon and the smartphone’s cooling system.
There’s little room inside a phone to dissipate tens of watts.
There’s no large heatsink like in a PC, and most models don’t have fans either. Heat has to pass through several layers before reaching a vapor chamber, a graphite sheet, the chassis, and finally the outside of the device.
Reducing any of those barriers can make a difference under sustained load.
The leak published now also shows the SM8975 and 101-BC references.
SM8975 had already appeared before in connection with the Snapdragon 8 Elite Gen 6 Pro in other leaks, but Qualcomm has not officially introduced a product under that name.
The conclusions about memory should also be treated with caution.
The initial reporting interprets the photographed unit as using LPDDR5X instead of LPDDR6. However, earlier leaks have claimed the Pro variant could support both technologies depending on configuration.
So the existence of one sample with LPDDR5X wouldn’t necessarily prove that the final product will skip LPDDR6.
The jump to N2P may help, but it doesn’t remove the thermal problem
Another piece of the story is the manufacturing process.
The leaks link the Snapdragon 8 Elite Gen 6 Pro to TSMC’s N2P, an evolution of the 2nm N2 node.
Here there is official information from TSMC.
The company began N2 volume production in the fourth quarter of 2025 and still plans to start N2P volume production in the second half of 2026.
TSMC describes N2P as an extension of N2 with additional performance and power improvements. It also notes that it uses the same core design rules as the N2 family.
According to figures published by the foundry, N2P would deliver roughly 5% more device performance than N2 and, compared with N3E, about 18% more performance, 36% lower power consumption, or close to 20% more density, depending on how the available margin is used.
These are figures TSMC provides for its manufacturing technology and cannot be directly translated into a Snapdragon’s final performance.
An SoC depends on its architecture, frequencies, voltages, caches, GPU, controllers, and the thermal design of the device it ends up in.
That’s precisely why the combination of N2P and a new package is more interesting than either technology on its own.
Cutting power per transistor helps, but raising frequencies can quickly eat that energy margin back up.
Thermal design is still necessary.
Qualcomm still hasn’t announced the Gen 6 Pro
It’s worth keeping a clear line between official information and leaks.
Qualcomm currently does not list the Snapdragon 8 Elite Gen 6 Pro among its publicly announced mobile platforms. Its official lineup still shows the Snapdragon 8 Elite Gen 5 as one of its current flagship offerings.
So the following are not officially confirmed:
| Feature | Current status |
|---|---|
| Snapdragon 8 Elite Gen 6 Pro | Leaked, not officially announced |
| SM8975 identifier | Appears in leaks |
| Heat Pass Block | Leaked, not confirmed by Qualcomm |
| Side-mounted DRAM | Suggested by the leaked image |
| LPDDR5X | Linked to the leaked sample |
| LPDDR6 | Mentioned in earlier leaks |
| TSMC N2P | Rumored for Qualcomm; the node itself is confirmed by TSMC |
| 5-6GHz frequencies | Rumored, not confirmed |
| Release date | Not announced |
This distinction is especially necessary here because some earlier reports have put the chip’s frequencies as high as 5 to 6GHz.
There is no official confirmation from Qualcomm on those figures.
It would also be premature to claim the new cooling will deliver “exceptional temperatures.” The design may improve heat transfer, but the outcome ultimately depends on the SoC’s actual power draw and on how each manufacturer integrates the vapor chamber, chassis, and other components.
The packaging change also comes with a trade-off.
If the assembly takes up more board space, manufacturers will need to set aside more room around the processor. In smartphones where the battery, cameras, antennas, and connectivity modules are already competing for every square centimeter, that change could force a redesign of part of the logic board.
Thermal engineering is once again feeding directly back into phone architecture.
For years, mobile SoC progress has mostly been told through nanometers, core counts, and frequencies. The Snapdragon 8 Elite Gen 6 Pro leak points to another, increasingly visible limit: it’s not enough to build a faster processor if the device can’t get rid of the heat it generates.
Frequently asked questions
Is the Snapdragon 8 Elite Gen 6 Pro confirmed?
No. Qualcomm has not officially announced the chip yet. Current information comes from leaks, images, and diagrams attributed to future samples.
What is a Heat Pass Block?
It’s a solution designed to improve heat transfer from the processor to the device’s thermal system. In the Snapdragon leaks, it would sit directly on top of the package.
Why could moving the DRAM help cool the chip?
By keeping memory from being stacked directly on top of the SoC, it becomes possible to create a more direct thermal path between the processor and the phone’s vapor chamber or heat spreader.
Will the Snapdragon 8 Elite Gen 6 Pro use LPDDR6?
That’s not confirmed yet. Some leaks point to compatibility with both LPDDR6 and LPDDR5X, while the photographed sample has specifically been linked to LPDDR5X.
