Taken from Engadget … the company later developed chipsets specifically for PCs, like the Snapdragon 850 and the 8cx. These resulted in laptops like the Surface Pro X and the Galaxy Book S, which are both gorgeous pieces of hardware that cost $999 to start. For PCs that don’t run all the Windows apps you might need, that’s exorbitant. Qualcomm seems aware, and announced today a couple of new additions to its made-for-PC series. The 8c and 7c are midrange and entry-level processors for the Windows on Snapdragon platform that help the company provide “various price points, allowing partners to design always on, always connected PCs for a wide array of consumers.”
The Snapdragon 8cx will remain the highest-end model, while the 8c sits right below it. It uses an octa-core Kryo 490 CPU and an Adreno 675 GPU, and was built on a 7nm process. Altogether, the Snapdragon 8c is up to 30 percent faster than the Snapdragon 850. It also features an X24 gigabit LTE modem, which should offer swift downloads over cellular data, and also works with the X55 5G modem to support up to 7 Gbps downloads (when networks and devices are ready).
Slide down to the entry-level rung and you’ll find the Snapdragon 7c, which uses the less-powerful octa-core Kryo 468 CPU and Adreno 618 GPU. It’s built on an 8nm process, which would be less efficient than the 8c. The 7c also uses a Snapdragon X15 LTE modem, that goes up to 800 Mbps instead of multi-gigabit rates like the 8c. Qualcomm also highlighted “multi-day battery life” as one of the draws here, that the 7c’s power efficiency will enable machines to hit that endurance mark.
