Bitcoin is the new currency of the Internet. Bitcoin mining is a new, kind of “underground” start-up, of a system of virtual currency used to buy goods and services over the Internet that is gaining in popularity. Home-built crypto currency mining is an excellent means to get involved in this scene without the cost of buying the coins outright.
First, some readers may be confused at this point about the two terms CPU, and GPU.
So, to clarify, the CPU, or Central Processing Unit, is the part of the computer that performs the core tasks of the software loaded on the computer. It’s in control of the entire machine. It tells all the other parts of the computer what to do, in accordance with the programming code of the software.
The GPU, or graphics processing unit, is a part of the video rendering system of a computer. The typical function of a GPU is to assist with the rendering of 3D graphics and visual effects so that the CPU doesn’t have to, but it can be used for other purposes and it is, of course, a very high speed and powerful processor which comes into its own running software which searches for bitcoin numbers.
Many people say that you will make money mining bitcoins, and recently some say that you can make something like $5 per day with an AMD 7950 GPU, but don’t forget to factor-in your electricity costs which will vary according to your supplier’s tarrif but may be $0.30 a day. You will most likely need to force your fan to run a little faster since your gpu will be running at 100% constantly. This can be done with most games motherboard set-ups which allow overclocking, if you watch temperatures for a while and adjust the fan speed. Do that until you are sure that the temperature of the GPU is staying within the manufacturer’s recommended temperature range.
The economics of it are going to be much more about the value that the wider community place on bitcoins at the time you sell, and the current rising value naturally makes it easier (for a while at least) to make money by bitcoin mining. But, the real question for us to establish is which is the best GPU to accelerate their computer and for the average games computer user to use to get started in the mining process.
Our research suggests (on the basis of the number of GPU card owners writing about this) that there is a significant difference between NVIDIA and AMD GPU (Radion) performance for bitcoin mining, and AMD cards are best for mining.
Some miners are using custom built racks containing 60 graphic cards or so, while others suggest that it is easy to make your own litecoin mining set-up with a single 7990 GPU.
