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.

Have this exact problem. The system had non-ECC memory, was running linux, and due to linux's file caching, the whole file was in memory. Person checksummed the in-memory file twice, thinking it was actually reading off the disk (because until recently, who had enough memory to have a whole large file in it?) and it checked out. Rebooted and decided to recheck it... different value. The initial two checksums had been wrong thanks to a bit error in the cached read-only copy of the file. If it had been committed whatever error it had could have corrupted the on-disk copy of the file.
Point being, as unlikely as it seems, the more memory you have, the more chances for a random bit flip damaging something important, even if you won't notice it now.
