Qualcomm announces the Snapdragon 8cx, an 'extreme' processor for Windows laptops
The "X" stands for "extreme." That's what Qualcomm's marketing department wants you to think about the new eight-core 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.
The TDP is 7 Watts, and the chip supports up to 16GB of LPDDR4x RAM.
Previously, a "Snapdragon 1000" for laptops was said to be in the works, but with a 12 Watt TDP.

Maybe, it's a question of scale. A datacenter running a million servers each with terabytes of RAM may encounter bit errors daily. An average consumer laptop, not so much.
Even if a bit flip happens, it can't do that much damage. In rough order of likeliness:
1. Nothing happens.
2. Video file is slightly corrupted (unnoticeable).
3. Some process crashes (unnoticeable, process gets restarted, worst case OS crash)
4. Some user document gets corrupted (restore from backup, many people use Dropbox et al now).
5. Some important file gets corrupted, the file is still well formatted, error goes unnoticed and causes problems for user later.
By 5, we're looking at getting struck by lightning levels of improbability.
