What's the best Graphics Card for Ethereum Mining?

Best Graphics Card for Ethereum Mining

If you are thinking of getting into Ethereum mining and start building your own Ethereum Mining Rig so this article helps you a lot for choosing best graphics card for mining ethereum. The main part of the GPU Mining is the graphics processing unit (GPU). The better you have graphics card, the more you get profits from Ethereum Mining.

best hardware for ethereum mining

First of all make sure what do you really want to optimize for?
Lowest upfront cost per unit hash rate?
Lowest ongoing cost (upfront + electricity)?
Best hash rate per unit electricity? Lowest heat (and electricity) per unit hash rate?

In my opinion, the best current GPUs are the following below for Ethereum mining but the answer is more complicated And all this depends on the cost of hardware and the cost of your electricity.

For the lowest heat and electricity per unit hash rate I would suggest R9 Nano.
Hash Rate: 28.5 mh/s  |  Cost: 497$  | You can get from here

For best hash rate per unit electricity I would suggest the R9 Fury X.
Hash Rate: 33 mh/s  |  Cost: 330$  | You can get from here

For the lowest upfront cost, possibly the R9 290
Hash Rate: 30 mh/s  |  Cost: 350$  | You can get from here

For the Hash Rate and electricity + cheap cost RX 390x
Hash Rate: 27.5 mh/s  |  Cost: 440$  | You can get from here

For the highest hash rate per GPU, the answer is the AMD HD 7990
Hast Rate: 44 mh/s  |  Cost: 588$  | You can get from here

The HD 7990 harder to purchase from stores as this series has been superseded by the R9 series released in 2015. Internally, the HD 7990 with 6Gb RAM consists of two AMD HD 7970 GPUs with 3Gb RAM each packaged together.

Here is a link to a site that allows you to compare the different GPUs - http://www.mininghwcomparison.com/list/index.php?brand=both . Type "Ethereum" in the filter.

You don't need a fast motherboard and CPU but make sure you know about this, AMD CPUs use more electricity than the equivalent Intel CPUs but AMD CPUs are cheaper than Intel CPUs.

Finally Now it's up to you which graphics card and hardware's you select for Mining Ethereum.

How to Build an Ethereum Mining Rig with Cheap Hardwares

Let's Start Building an Ethereum Mining Rig

Here in this mining rig guide, we will guide you to selecting the best ethereum mining hardware, to get you very own ethereum mining rig. Once this rig is fully assembled and configured correctly, it is capable of securing the ethereum network and earning you real money in ether.

Ethereum Mining Rig

List of hardware you need to build your ethereum mining rig:

1- Graphics Card:

This is most important hardware for ethereum mining rig. In this guide we use Radeon RX 480 8GB graphics cards. If you shop around, you can pick these up for around $200-250 and they will each produce about 25MH/s of mining speed. Their price point and power consumption specifications make them an ideal graphics card for ethereum mining. You can get graphic card from here

2- Motherboard:

A motherboard is the brain of the computer and is what you build everything onto the base of your mining rig. The main feature you are looking for in a motherboard is the number of GPU slots it has as this will determine how many graphics cards or GPU's it can fit - and in the end your total hashing power. 3 PCI Express slots will mean you can fit 3 x Radeon RX 480 with a hashrate of 25 MH/s each - or a total hashing power of 75 MH/s.  This motherboard allows you to connect 6 GPU’s on powered PCI-e riser cables and since the CPU power is irrelevant to mining, we’ve chosen the cheapest compatible CPU on the market for this motherboard. We used the GA-Z97X-Gaming 3 which you can get here

3- PSU or Power Supply:

The key here is to have an efficient power supply that will save you over the long run in electricity costs. This is the industry standard for rating the efficiency of a PSU. If you are building a "mega rig" which has 6 GPU's you might find it more cost effective to have two separate power supplies because at 750 Watts and $100 each rather than a 1500 W and $300 dollars! We got a Seasonic 1200 Watt which you can buy here.

4- Hard drive:

You need a hard drive to store your operating system and your software for mining ethereum. A standard SSD drive will do work. We used the SSDNow V300 120GB. Buy it here.

5- Ram: 

You don’t need a lot of system memory to mine ethereum effectively. 4GB is about as small as a stick of RAM comes these days, so I recommend just picking up a cheap one for about $20. Which you can get here.

6- Case:

You can build one of these yourself with angled aluminum from your local hardware store. There are several custom case builders selling these as well. I can personally recommend the custom built cases designed and built by Rich Chomiczewski.

Assembling Hardware for ethereum mining rig:

First of all un-package all hardware you purchased. Now assemble your mining case than install hard drive and Ram in your mother board. Place motherboard in custom open air mining rig case and connect motherboard PSU connector (leaving PSU unplugged from the wall of course). Connect all GPUs to riser cables and fasten them to custom case. You might need to experiment for optimal spacing to keep the cards cool. Plug in all power supply connections. Connect mouse, monitor and keyboard and an internet connection (I use a USB WiFi adapter). Check all connections once more.  Install the OS if needed. Install Graphics card drivers. Install ethereum mining software. Make sure fans are fully functional. Start the ethereum mining software, tweak settings for maximum hash rates and let it run!

That's it finally you have made your own ethereum mining rig with cheapest hardware.
