GeForce RTX 3090: This is the fastest graphics card right now, for mining and gaming purposes, and it's the only Nvidia Ampere GPU that won't be replaced by an LHR equivalent.

What is GPU mining & how does it work?

Here’s a breakdown of what GPU mining is and how it has started to cause real problems for the hardware industries it draws from. What is mining, and how do GPUs accomplish it? Mining is essentially running software to solve complex mathematical problems in order to verify transactions on a cryptographic blockchain.

Can GPUs be used to mine bitcoin & litecoin?

Unfortunately, this has contributed to the current GPU shortage and led Nvidia to limit the hash rate of newer 30-series cards. Despite the massive drawbacks to mining Bitcoin and Litecoin on graphics cards, the upside is that graphics cards can still be sold in the aftermarket because of their general-purpose use.

Is AMD nerfing the mining capabilities on its graphics cards?

AMD confirmed as much when they said had no plans to nerf the mining capabilities on its graphics cards, like Nvidia supposedly planned to do with some RTX 3000 series chips. The most you can expect to get out of these cards is 60-65 MH per second with a power consumption of 160-190 watts.
