The GPU’s Video RAM (VRAM) is its "workspace." Many proof-of-work coins use a Directed Acyclic Graph (DAG) file that grows over time. If you buy a card with only 4GB of VRAM, you'll find yourself locked out of mining major assets as their DAG files exceed your hardware’s capacity. Aim for at least to ensure your hardware stays relevant for several years. 3. Thermal Management
Choosing a GPU for mining is no longer the straightforward "buy the biggest card" decision it was a few years ago. With changes in blockchain consensus mechanisms and fluctuating energy costs, a successful purchase now requires a balance of , efficiency , and resale value . 1. Performance vs. Efficiency buy gpu for mining
Mining puts a constant, 24/7 load on hardware. Unlike gaming, where the load fluctuates, mining generates steady, intense heat. When selecting a card, pay attention to the cooling solution. Cards with three fans or robust heat sinks will last longer and maintain higher speeds without "thermal throttling," which is when a card slows itself down to avoid permanent damage. 4.
