The Most Profitable Mining GPU in 2024

The table shows the most profitable graphics cards that can be used for cryptocurrency mining. Cards are sorted by the daily reward from the most powerful to least. The most profitable mining algorithm and coin are taken into account for each graphics card.

When choosing the best video card for mining we do recommend to consider not only the profitability but also the energy efficiency and price of each card. GPU price information is taken from Amazon, ComputerUniverse, Ebay. Payback is calculated based on the GPU price and current Mining Profit. Electricity costs, future mining difficulty and cryptocurrency price change are not taken into account.
