Early crypto miners mainly used their home computers to engage in Bitcoin mining activities. However, the increasing market demand for cryptocurrencies rendered home computers inefficient for Bitcoin mining due to their limited processing speeds and high power consumption. That gave way to Graphics Processing Units (GPUs), considered more efficient than their predecessors. The following article explores GPU-based Bitcoin mining and its unique benefits over other mining alternatives. You can check oilprofits.de to learn more about bitcoin trading.
What is a GPU?
A Graphics Processing Unit (GPU) is computer hardware responsible for rendering 3D graphics and shapes. That mainly entails running complex mathematical calculations in a parallel manner. Modern GPUs have thousands of parallel processing cores to solve the tricky mathematical puzzles involved in Bitcoin mining.
Bitcoin miners run specialized software to solve complex math problems to verify transactions on the blockchain. The crypto miner that solves the puzzle first gets rewarded in Bitcoin. GPUs have become popular with crypto miners because they have greater processing power, enabling them to solve complex math puzzles quickly and efficiently.
How GPUs Work in Bitcoin Mining
As hinted above, crypto mining mainly began with Central Processing Units (CPUs). However, miners soon realized their output was quite limited as transactions increased exponentially. That led to the discovery of GPUs, with robust benefits over CPUs.
A Standard GPU, for example, a Radeon HD 5970, can execute about 3,200 32-bit instructions per clock. And that is 800 times more than a standard CPU’s processing speed of only four 32-bit instructions per clock.
The GPU’s high processing speeds are one of the main characteristics that make them ideal for Bitcoin mining. It renders them more efficient in performing similar computational tasks repetitively. The devices constantly try to decode different hashes repeatedly, with only one digital change in every attempt.
Graphics Processing Units also have more Arithmetic Logic Units (ALU), responsible for running mathematical computations. That enables them to handle more calculations, significantly improving the Bitcoin mining process’s overall output.
Comparing GPUs and CPUs
Every computer has an in-built Central Processing Unit (CPU), serving as the device’s brain and performing all its control functions based on its operating system’s logic and the software installed therein. The CPU controls functions such as saving documents and even running media files.
A GPU is also a processing device but works solely in handling display functions. It is the computer component that supports video rendering. Its typical role involves performing and controlling visual effects and 3D graphics rendering. A GPU supports graphics-intensive tasks such as gaming display, video editing, decoding, and rendering 3D videos and animations.
The CPU is the master, managing the entire organization (computer system), while the GPU is a department tasked with specialized tasks.
That kind of setup allows the CPU to perform the diversified high-level tasks of managing the entire device, as the GPU only handles video functions where it is best suited.
Although Graphics Processing Units have been around for many years and are more efficient than CPUs, they also face increased competition from other improved devices. The Application-Specific Integrated Circuits (ASICs) and Field Programmable Gate Arrays (FPGAs) have scored better than CPUs and GPUs in hash calculations. They can be custom-built to calculate specific hash algorithms, with more incredible cost-saving benefits.
GPUs are undoubtedly popular among Bitcoin miners mainly due to their higher processing speeds and efficiency. However, consider the other options mentioned above to determine the most suitable way for you to engage in Bitcoin mining.
