Bitaigen Research We, the Bitaigen editorial team, have compiled the latest 2021 real‑world benchmark data for NVIDIA and AMD graphics cards when mining Ethereum (ETH) and Conflux (CFX). In addition, we provide recommendations for power supply, cooling, and overclocking configurations. This article compares the performance of each card, helping newcomers quickly identify the most efficient GPUs. Please continue reading for the full details.
Special Note
When evaluating a graphics card for mining, the power draw of a single GPU represents only part of the total system consumption. The motherboard, CPU, storage, and other supporting components typically require an additional 100 W‑200 W. If the entire mining rig (GPU + platform) consumes roughly 1,000 W, it is advisable to select a power supply rated at 1,250 W or higher and to leave a 20%‑30% headroom. This margin compensates for any optimistic power‑rating claims and helps ensure long‑term, stable operation.

In recent years, the cryptocurrency market has been strong, attracting many newcomers. A common question that follows is: what are the actual hashrates and power consumptions of different GPUs when mining Ethereum (ETH) versus Conflux (CFX)? While various data points are available online, most are outdated and no longer reflect current conditions. To address this, we have assembled a list of the most recent real‑world measurements for the two major brands, NVIDIA and AMD, taken on 2021‑03‑03. The list will be updated continuously as newer data become available.
Hashrate performance is influenced by the GPU driver version, mining kernel, overclocking level, and the card’s cooling capability. Some models can achieve a noticeable boost after overclocking, while others may become frequency‑limited or unstable. Therefore, the numbers shown below should be regarded as the results of actual testing under the conditions described.

NVIDIA GPUs – Conflux (CFX) Hashrate Ranking
*(Only NVIDIA cards with 8 GB of VRAM are suitable for CFX mining; within the same VRAM class, the 2‑series generally yields slightly higher returns than the 3‑series, while the 3‑series excels in ETH mining. Actual profitability still depends on coin price, total network hashrate, and difficulty.)*

|---|---|---|---|
| 2060 SUPER | CFX | 48 M | 160 W |
| 2070 | CFX | 52 M | 156 W |

Closing Remarks
All figures presented above are sourced from multiple experienced miners and reflect the state of the hardware as of 2021‑03‑03. Variations in mining software kernels, GPU overclock settings, and driver versions can cause real‑world hashrates to deviate from the numbers listed, especially for less common GPU models. We welcome feedback from readers to help us refine and expand the dataset.
The graphics‑card market continues to exhibit significant price premiums. Bitaigen does not recommend blindly jumping into mining without thorough research. Cryptocurrency mining is inherently high‑risk, and prospective participants should conduct a careful risk assessment before committing capital.
