The Best GPUs for Mining – 2018 Edition

Date: Monday, May 28, 2018 4:14 PM EDT

Cryptocurrency mining has gotten more competitive over the last five years and as cryptocurrencies have seen enormous gains, this has fueled a race for more efficient means of mining. While huge mining facilities with ample budgets can afford to go with all ASIC (Application Specific Integrated Circuit) chips, most home miners are using CPU or GPUs to operate their nodes. In this article, we’ll briefly go over what a GPU miner is and compare the best GPUs for mining currently on the market.

A CPU or Central Processing Unit is the main chip of your home PC.This is the actual processor that performs the software functions that are programmed into your computer.Think of your CPU as the brain of your computer, it’s what tells your PC what action to execute and in what manner.Today’s PCs can have multiple CPUs or even multicore CPUs directly integrated into their motherboard.

A GPU (Graphics Processing Unit) is designed to handle the labor-intensive tasks of rendering graphics.These are critical in allowing your PC to function smoothly during graphic-heavy applications.While many computers have integrated GPUs on their motherboard, a more advanced PC will feature a completely separate GPU to handle the intense graphical demands of today’s PC applications.

A CPU core can handle 4 32-bit instructions per clock whereas a GPU such as the Radeon HD 5970 can execute 3200 32-bit instructions per clock.This is a huge difference in computing power.Think of your CPU as the foreman on your computers construction site and your GPU as the workers.GPUs posses more ALU’s (Arithmetic Logic Units); this is what’s used when handling the complex mathematical equations found in proof-of-work systems.

Your CPU is designed to be smart and flexible because it must handle a wide range of tasks related to the operations of your PC, whereas, a GPU is designed to be strong and repetitive.Your GPU is perfectly suited to repeat the same math equation a million times until it finds the correct answer.
