The “X” stands for “extreme.” That’s what Qualcomm’s marketing department wants you to think about the new Snapdragon 8cx.

It’s a brand-new processor for always-connected Windows laptops and 2-in-1 convertible PCs, and from Qualcomm’s perspective, it might seem a little extreme. Physically, it’s the largest processor the company has ever made, with the most powerful CPU and GPU Qualcomm has devised yet. Qualcomm says it’ll be the first 7nm chip for a PC platform, beating a struggling Intel to the punch, and the biggest performance leap for a Snapdragon ever. The company’s promising “amazing battery life,” and up to 2Gbps cellular connectivity.
