ATI graphics card model mining

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

2. Because amd graphics card provides a large number of simple computing resources, which is suitable for high-intensity and heavy load computing,
while NVIDIA graphics card provides less computing resources, mainly through software optimization to achieve game acceleration. In addition, game n card simplifies some moles used in scientific computing (mining just belongs to this kind of Computing),
therefore, in the face of mining, which is a simple and high load operation, the N card with weak body will not work

for now, the design between AMD and NVIDIA is more and more similar. The a-card part absorbs the advantages of serial and branch judgment of n-card, and the n-card part also adopts the simple violence stack design of a-card. So who has the advantage is a mathematical proportion problem, whose graphics card is more accurate to the proportion planning of game resources, whose performance is better

so mining depends on the efficiency of the algorithm. A card is really good at an algorithm called SHA-256, which was used in violent decoding before (so a card also has a good performance in violent decoding)

unfortunately, in order to rece the power consumption, n card has actually simplified some scientific computing moles. As we said downstairs, the CPU is good at the work of branch judgment. N card no longer relies on itself, instead, it has been deleted, leaving this part of the work to the CPU to the processor, so the general computing performance is weaker than a card. As for the advantages of N card in the field of professional card for a card mentioned by some people, it mainly depends on the early investment and construction in the application of software in the past, that is, the early optimization is still in place, and now the old customers are still eating well

it is true that Tianhe first used 4870 as accelerator card, but there may be a mistake, that is, it was not NVIDIA's Tesla that was used by new Tianhe, but Titan, another supercomputer, which was not entirely Tesla processor, but also AMD's Haolong processor for collaborative computing. In fact, tianhe-2 uses Intel's Xeon Phi processor, neither amd nor NVIDIA.

3. The reason is that the graphics rendering architecture of NV is well optimized and the core utilization rate is high. Therefore, under the same graphics rendering performance (almost the same price), NV does not have the same hardware resources as AMD, that is, the stream processor or computing unit is much less than AMD, The number of fury
x
4096 stream processors and high-speed HBM video memory can't match the number of GTX
980ti
2816 stream processors, but the pure computing power is still very strong. Mining is easier to achieve higher core utilization, while graphics rendering is very difficult, which depends heavily on the graphics architecture. Of course, GPU mining has long been out of date. They are all ASIC circuits with high performance and low power consumption
the above is the content. It answers your question very well

4. Before the appearance of mining machine in 2012, the era of mining with graphics card used a card, because mining is to split hash operation into multiple sub operations. At that time, a card can complete one operation with one instruction set, while n card needs three instruction sets to complete one operation. Therefore, the actual operation efficiency of a card is more than twice that of N card, which is close to three times

in fact, n card has greatly enhanced the mining efficiency in the Maxwell architecture, not inferior to a card. But the Maxwell architecture came out too late. When the earliest Maxwell architecture graphics card, such as gtx750ti / 750, came into the market (early 2014), the mainstream currencies could not dig out anything with graphics cards (all mining machines). Therefore, few people use n-card mining.

5. The first phase of a card is hd7850 7870 7950 7970 R9 270-380, which is basically OK, and the 290 power consumption is too high to be used by mine owners.
in the second phase, the above old cards are still available, and the most perfect one is 470 480 570 580 low-end 560, which can also be used to dig lower models. There is no danger.
n card 1060 3G 6G is the most mainstream, 1050ti and 1070 are occasionally used. Especially luxury also used 1080, because the price of 1060 was almost 1080 at that time

8. Smart home is a terminal of Internet of things, and the effective connection between each terminal needs the technical support of cloud service and IPv6. The establishment of smart home standard is inseparable from them
the establishment of an instry standard also needs the following two conditions:
first, practical, efficient and feasible technical standards: the graal establishment of cloud services, Internet of things and IPv6, which makes the technical standards clear, but also has a lot of uncertainty
Second, enough instry influence: at this stage, most of the smart home solutions and procts manufacturers still stay in the physical control layer, and no one has enough instry influence
so now there is no standard for smart home, but the emergence of this standard will be inevitable
at this stage, ZigBee and Z-Wave are the two most representative technical standards for smart home control system standards. ZigBee protocol starts from the architecture of Internet of things, and Z-Wave is specially customized for smart home. However, the enterprises using these standards are still in the early stage of development e to the limitations of peripheral facilities, cost and technical perfection. Throughout the market, smart home procts are still in the primary stage of physical control, and there is no obvious connection between informatization, cloud services and Internet of things
the development of domestic smart home system is also very rapid in recent years, almost following the pace of international development. Haier and others in the early stage also have great changes after the first round of shuffling. Now the domestic smart home technology is dominated by rf315, 433 radio frequency 2262.1527 standard protocol, which has low threshold and low development cost, In the early stage of the development of the market has played a very good role in promoting, and with the maturity of the market, the defects of technology graally exposed, those who did not make technological transformation of the company are dismal
after the first round of reshuffle, some new technologies have emerged, with 2.4G and 433 carriers as the most representative. In terms of protocol composition, ZigBee networking technology has great advantages in terms of cost, and adheres to the development of cloud service architecture. Voice control function makes the control from physical control to content control, It has achieved effective integration with Internet of things and cloud services
in terms of market promotion, the OEM scheme is adopted to accelerate the market share of smart home. From these two points, it is not difficult to see that Shenfu smart company is also going to the standard. Through market feedback, the integrity of the agreement can be continuously improved, and the development risk of other smart home brands can be reced by means of technology, so as to obtain the market share. The direction is right, The method is good, but I don't know how far I can go
although there is no standard for smart home for the time being, with the graal maturity of the market, after several rounds of market adjustment and reshuffle, the technology used by the companies standing in the market will be the standard. The author thinks that the market standard can never be discussed by a group of experts, and it must be eliminated through the baptism of the market. I hope that in the future, the establishment of international standards will be the basis for the development of smart home, We can see the figure of Chinese enterprises
