When you hear GPU mining, the process of using graphics processing units to solve complex math problems and earn cryptocurrency rewards. Also known as graphics card mining, it was the backbone of Bitcoin and Ethereum mining before the industry shifted. Unlike CPUs, which were designed for general tasks, GPUs handle thousands of calculations at once—making them perfect for cracking cryptographic puzzles that secure blockchains.
GPU mining doesn’t just mean running software on your gaming rig. It’s a whole system: mining hardware, specialized components like ASIC-resistant GPUs, cooling setups, and power supplies built for 24/7 operation, paired with mining software, tools like NiceHash, PhoenixMiner, or T-Rex that connect your rig to a blockchain network. You also need a wallet to store what you earn. The goal? Solve blocks faster than others to earn block rewards and transaction fees.
Even though Ethereum moved to proof-of-stake in 2022, GPU mining didn’t die—it just found new homes. Coins like Ravencoin, Ergo, and Monero still rely on GPU-friendly algorithms. Many miners switched to these, or started mining on smaller networks that value decentralization over speed. Others repurposed their rigs for AI training, rendering, or even hosting decentralized cloud services. The hardware didn’t become useless—it just needed a new job.
Still, GPU mining isn’t for everyone. Electricity costs can eat your profits fast. A single high-end card might pull 200 watts—add six of them, and you’re looking at a $150+ monthly power bill in some regions. And if the price of your mined coin drops, you could be losing money. That’s why smart miners track market rotations, compare pool fees, and keep an eye on coin fundamentals—not just hash rates.
What you’ll find below isn’t a list of the best GPUs or how to overclock your rig. It’s a collection of real stories, warnings, and breakdowns from people who’ve been there. You’ll see how some miners lost everything after switching to a coin that vanished overnight. You’ll read about exchanges that claimed to offer "cloud mining" but were just scams. And you’ll find out why some coins still reward GPU miners while others left them behind.
GPU mining offers flexibility and resale value for altcoins, while ASIC mining dominates Bitcoin with unmatched efficiency. Learn which hardware suits your goals, budget, and electricity costs in 2025.
