Qualcomm recently introduced its new Snapdragon X series of processors for Windows on Arm laptops. The company revealed four chipsets in the line, where three of them belong to the Snapdragon X Elite tier while the remaining is the Snapdragon X Plus which will power more affordable Windows laptops.
However, according to industry insider Kamila Wojciechowska (via Android Authority), Qualcomm might have further plans for the Snapdragon X Plus lineup. The tipster says Qualcomm is working on a second and more powerful variant of the X Plus chipset, called X1P-42-100.
It will feature eight Oryon CPU cores, up from six on the X1P-64-100. Notably, the X1P-42-100 is rumored to lack the four efficiency cores present in its counterpart.
While this could translate to better performance for the X1P-42-100, it comes with fewer PCIe lanes compared to the X1P-64-100.
Here’s the table showing the specs of all the SoCs in the Snapdragon X line:
| X1 Elite (X1E-84-100) | X1 Elite (X1E-80-100) | X1 Elite (X1E-78-100) | X1 Plus (X1P-64-100) | X1 Plus (X1P-42-100) | |
|---|---|---|---|---|---|
| Performance cores | 8x Oryon – 3.8GHz | 8x Oryon – 3.4GHz | 8x Oryon – 3.4GHz | 6x Oryon – 3.4GHz | 8x Oryon – ? |
| Efficiency cores | 4x Oryon – 3.8GHz | 4x Oryon – 3.4GHz | 4x Oryon – 3.4GHz | 4x Oryon – 3.4GHz | – |
| Turbo | 4.2GHz up to two cores | 4.0GHz up to two cores | – | – | – |
| GPU frequency | 1.5GHz | 1.25GHz | 1.25GHz | 1.25GHz | ? |
| Video hardware | 4K 60 fps encode, 4K 120 fps decode | 4K 60 fps encode, 4K 120 fps decode | 4K 60 fps encode, 4K 120 fps decode | 4K 60 fps encode, 4K 120 fps decode | 4K 30 fps encode, 4K 60 fps decode |
| PCIe | 8+4 lanes of PCIe 4.0, 2+2 lanes of PCIe 3.0 | 8+4 lanes of PCIe 4.0, 2+2 lanes of PCIe 3.0 | 8+4 lanes of PCIe 4.0, 2+2 lanes of PCIe 3.0 | 8+4 lanes of PCIe 4.0, 2+2 lanes of PCIe 3.0 | 4+4 lanes of PCIe 4.0, 2+2 lanes of PCIe 3.0 |
The X1P-42-100 is also said to have limitations in video encoding and decoding capabilities, supposedly capped at 4K/30 FPS encoding and 4K/60 FPS decoding.
In contrast, the X1P-64-100 is rumored to offer 4K/60 FPS encoding and 4K/120 FPS decoding. Many other details about the X1P-42-100, such as CPU clock speeds and GPU specifications, remain under wraps for the time being.
Wojciechowska’s leaks extend beyond the X series, suggesting Qualcomm is also working on a server-grade chipset codenamed “SD1”. The processor is purported to feature 80 Oryon cores on a 9470-pin LGA socket and will use TSMC’s 5nm (N5P) production process.
The leak also suggests that SD1 will support 16 channels of DDR5-5600 RAM, boast 70 PCIe 5.0 lanes, and have the capability to run two chipsets simultaneously.
Furthermore, Wojciechowska mentions that the SD1 integrates Compute Express Link (CXL) 1.1. However, other details about the silicon are unclear at this stage.
