Editor's Note:
Update: We now have published details on how this SiP memory architecture affects real-world power draw. Read our deep dive on the Snapdragon X2 Elite Extreme's power limits and TDP scaling here.
It is not just the specifications that convey a clear message that Qualcomm’s Snapdragon X2 Elite Extreme is significantly different from the two Snapdragon X2 Elite chipsets that the company announced a few hours ago. A look at the die package confirms this contrast, showing that the San Diego firm’s most powerful silicon for notebook computers features SiP memory, which is what allows it to reach such high bandwidth levels.
The maximum memory bandwidth of the Snapdragon X2 Elite Extreme is 50 percent higher than the Snapdragon X2 Elite, thanks to the inclusion of SiP memory
For those who do not know, System-in-Package (SiP), integrates multiple circuits and components such as RAM, storage and other parts to form a single package. This design approach helps conserve internal space for constrained products like laptops, while also contributing to improved efficiency and increased memory speeds. Since the RAM is placed right next to the chipset, both components will take less time to communicate and perform the required tasks, resulting in increased memory bandwidth.
The SiP memory packaging layout of the Snapdragon X2 Elite Extreme reminds us of Apple’s unified RAM architecture, which lets the CPU and GPU use the same memory bank, making the entire SoC more efficient. Of course, it should be noted that both architectures have massive differences in core functionality, but the message we were trying to inform readers was that the arrangement of the components was similar.
This package shift would explain why the Snapdragon X2 Elite Extreme has a memory bandwidth of 228GB/s, and ships with a minimum of 48GB. The remaining Snapdragon X2 Elite SKUs feature off-package memory, and as a result, have a lower 152GB/s bandwidth. In the image shared by @IanCutress, we can see the ‘SEC’ label, confirming that Qualcomm is sourcing chips from Samsung to complete the package.
The entire die is certainly not a slouch in the size department, which is no surprise given the components it is packing. Notebook manufacturers that intend to employ the Snapdragon X2 Elite Extreme in their notebooks scheduled to arrive in the first half of 2026 will need to ensure that there is sufficient cooling for the chipset to reach its full potential.
