GPU digs BTC

1.

The first step in setting up mining equipment is to choose the right hardware. This article will focus on GPU (graphics card) mining, of course, you can use CPU or ASIC equipment mining. Amd graphics card architecture is very beneficial to mining. NVIDIA card is not suitable for mining because of its low hash rate. The best NVIDIA graphics cards are less than 0.5 megahash. Notebook Hardware mining is not as good as NVIDIA card, which is a bad option for mining. You need to use a desktop system for mining. There is a desktop system to ensure adequate cooling of the hardware

the graphics card or card needs to be able to match the motherboard, and the power supply must have enough PCI-E connectors. Before determining the graphics card, pay attention to these. In order for the system to cool down sufficiently, you need to remove the cover of the chassis in order to get better heat dissipation. This is what people call "open air rig.". If you can aim the system at a fan or air conditioner, you can make the device cooler when it's running, thus extending its life and keeping it efficient

Amd graphics card is recommended for bitcoin, n card is not suitable

moreover, one video card can't dig one coin a week, so it needs several amd video cards to dig together, and some even use mining machines. At present, mining on the computer platform is unprofitable for ordinary users unless they are professional players

3. 1. CPU is mainly optimized for serial instructions, while GPU is optimized for massively parallel operations
2. Modern multi-core CPU aims at instruction set parallelism (ILP) and task parallelism (TLP), while GPU is data parallelism (DLP)
3. GPU often has a larger bandwidth of memory, that is, the so-called video memory, so it will also have good performance in high throughput applications
4. CPU is a general-purpose operation. In short, it means brainless calculation and violent calculation. Whether it's 100 children sharing apples or simulating the earth, it can be decomposed into the most basic calculation of 1 + 1 = 2. GPU is specially designed to deal with high-order mathematical algorithms, such as calculating the relative positions of light source, object, viewpoint and shadow, which requires trigonometric functions to be piled up. The bitcoin digger uses SHA-256, a secure hash function invented by the US National Security Agency, which is generally used for password encryption and decryption. This algorithm can perform a large number of 32-bit integer right-rotate operations, which is very suitable for GPU which is good at large-scale concurrent computing and password cracking.

4. Now to dig out a bitcoin, it costs about 10000 yuan for electricity, and it's a large computer. Ordinary people don't need to dig. First, there is no large-scale computer. Second, the cost is too high. The electricity bill alone costs 10000 yuan

5. It is said that using bitcoin to mine is AMD's graphics card (and it must be high-end graphics card, that is, the price is more than 2000 yuan) with a higher success rate. This is a "bitcoin" article in a certain issue of popular software, a famous computer magazine in 2012.

6. At least dozens of times as much as CPU, and bitcoin uses OpenCL. The efficiency of 7 series a card is much higher than that of N card.

7. Our country is against digital currency.

8. Bitcoin mining period: a business that can't recover its capital, bitcoin. This brings a large number of speculators, and at the same time, it also makes a lot of people think about mining. How do the miners do?

9. The principle of digging bitcoin is to calculate the decryption result according to a certain mathematical formula, which corresponds to a certain amount of bitcoin. The video card's stream processor is large in scale, which is more efficient than CPU in computing virtual token. For example, rx480 has more than 2000 stream processors forming a GPU core. This structure is suitable for mining. The relative CPU is generally 2-core to 6-core, which is suitable for complex operations. CPU is equivalent to contractor, GPU is equivalent to worker, and mining depends on worker.
