A mock up of the rumored RTX 3090 graphics card.

Word on the vine is that NVIDIA is planning to fabricate the next generation RTX 3000 Ampere GPUs on Samsung's 8nm process. This would be somewhat unexpected as NVIDIA's announcement for Ampere has previously stated that they will be using the 7nm TSMC process. The leaker in question, however, has an excellent track record for RTX 3000 series leaks and had the die configurations down pat months before anyone else. This is why even though I am tagging this as a rumor simply because of the sheer contrarian nature of this article; let's just say I wouldn't be surprised if it turns out to be true.
