Best GPU for Mining Ethereum – Buyer’s Guide

Oh boy! What a time to mine some cryptos. Ethereum gas surged past USD 4,000, and we don’t know when the rise will stop. So even the newbies are rushing into the industry to get the best GPU for mining Ethereum. Ethereum mining with GPUs has been practical and does not require specialized ASIC-based mining rigs, but GPU-based computation from mainstream players can get you in the business.

This is the best time to invest in a severe Ethereum mining rig. Unfortunately, all the big hardware manufacturers have already sold out their best offerings. So, let’s take a look at some of the coolest and best GPUs to augment your Ethereum mining hardware.

Mostly, all graphics cards (GPUs) you will consider will be from either Nvidia or AMD. Both are big solid companies known for making GPUs that can be used for mining and gaming. Unless of exceptional circumstances, you can choose Nvidia or AMD and any other producer of the cards. But you will want to preference the GPU model carefully as they vary widely in memory sizes, memory speeds, wattage, and price. You don’t want to buy it and find out it doesn’t have enough memory for Ethereum mining.

Which is Best Ethereum Mining Hardware?

Ethereum mining is done using the Ethash algorithm, which can be exploited using powerful GPUs. For Ether mining to be profitable, you need to have the right hardware at the right price.

In addition, there are two major GPU manufacturers to choose from AMD and NVIDIA. Finally, it’s essential to keep track of Ethereum’s Casper update, rendering Ethereum mining obsolete.

If you want a comprehensive review of the different mining hardware, keep on reading. Here’s what I’ll cover:

Ethereum Mining Basics

If you’re new to Ethereum mining, there are three crucial things you should know:

  1. Ethereum Proof of Stake Update
  2. VRAM Requirements
  3. Mining Demand Drives Up GPUs Cost

Ethereum Proof of Stake Update

Using an algorithm called Casper, Ethereum developers are planning to switch to Proof Of Stake. Unfortunately, this switch will render Ethereum as we know it obsolete. The good news is that this update applies to Ethereum only. Other crypto coins using Ethash will not be affected, so your cards will still be able to function correctly by mining other Ethash coins.

VRAM Requirements

One important thing to look out for before buying mining hardware to mine Ethash is the Directed Acyclic Graph (DAG). Without going into details, a DAG is a file created every 30,000 Ethereum blocks. Since the DAG is stored in the VRAM of the GPU, your graphics card must have enough storage to load the DAG in. Because of this, you can only mine Ethereum with cards that have at least 4GB of VRAM.

Nevertheless, that might not be the case for other Ethash-based coins. So, in case you have old 2GB graphics cards at home and you’re new to crypto mining, you can try it out on other crypto coins first.

Mining Demand Drives Up GPUs Cost

Not long ago, GPU-based cryptocurrency mining stretched such a popularity level that the two companies producing GPUs (NVIDIA and AMD) could no longer supply the demand. This made retailers and secondary market sellers hike their prices.

An essential skill for a good miner is to hunt for deals where graphic cards are moderately priced. This can be done by checking out offline, online stores, and other secondary market outlets.

Additional Hardware Requirements

While the GPU is arguably the most crucial component in Ethereum mining, your system’s hardware must match certain specifications. Here’s what I recommend:

  • For Ethereum mining rigs of less than 6 GPUs, 4GB RAM is required. For more than that, I commend getting an 8GB RAM stick.
  • A motherboard with enough PCIe inputs is a crucial thing to look for in your motherboard; if you are building a multiple GPU Ether mining rig, your motherboard needs to have sufficient PCIe inputs to hold them.
  • A Powered riser cable for each graphics card.
  • An open-air rig for multiple GPUs.
  • A good power supply.
  • A good internet connection.

Etherium Mining Software Requirements

Mining also requires specific software such as drivers and programs. Some of these are GPU specific, so I’ll list only the common ones here:

  1. Temperature Monitoring and Overclocking Software
  2. Mining Software

Temperature Monitoring and Overclocking Software

This software program is intended to be used to tweak your GPU performance. It will make your GPU mine healthier (more hashes/secs), mine cooler (lower temperature is always suitable for the graphics cards), and mine more efficiently (consuming less power). Most miners use GPU-Z for temperature and power monitoring and MSI afterburner overclocking software.

Mining Software

Most people use the Claymore software for mining Ethash coins as it is one of the oldest and most supported Ethash miners. Some other programs have been surfacing since, such as Phoenix and Ethminer miner.


Nvidia vs. AMD

Nvidia graphics cards are easier to use, overclock, and configure (i.e., squeeze more juice out of the GPU). Nvidia cards do not need a long time to learn how to configure them, flash bios, or undervolt.

However, there’s a tradeoff. AMD graphics cards are more suitable for the beginner miner in terms of price, as the base of AMD mining cards prices nearly 2/3 the price of its Nvidia counterpart.

AMD-based GPUs are also not as powerful as Nvidia’s. Another critical advantage of Nvidia cards is that they are improved on a variety of other algorithms. While AMD cards are more efficient on Ethash and the Cryptonight algorithms, Nvidia cards beat them on most others.


Choosing Mining Hardware

I’ve compiled stats on the best available graphics cards, which should help you decide which one to pick. Here’s a detailed explanation of the criteria:

Name

The chipset’s name produced by NVIDIA or AMD for each card remains the same, while the model can vary. Some variations can also have better performance out-of-the-box as they can come factory overclocked, but this can be compensated by overclocking software.

Hash Rate

The rate the graphics card achieves under ideal mining conditions and will be given as a range, which can be reached by overclocking, undervolting, or flashing a BIOS.

Power Draw

Power draw is the amount of electricity or power a card consumes while mining cryptocurrency, which is measured at the outlet.

Efficiency

Efficiency is measured by dividing the hash rate by power consumption. Newer GPUs are usually more efficient.
