Hd6950 mining efficiency

1. It's really difficult to mine now. First of all, determine whether your positioning is correct. As mentioned above, you may not be able to play one in eight years in ten years. Of course, you are lucky to dig out a few in one year, but this is gambling. The probability is very small, ha ha

however, you really regard mining as fun and entertainment. If you don't care much about whether you can dig, you can also let your own machine dig all the time. However, the machine configuration above you should not be low, but it is not suitable for mining, just as the swimming champion is not necessarily good at mountain climbing

generally speaking, mining machines mainly focus on graphics cards, which have little to do with processors, main memory boards and hard disks. Of course, they need to be stable and not crash for a long time. In fact, a card is more suitable for mining. In principle, you can go to the network. It is said that before the emergence of R-Series a card, the card with good mining effect was not hd88708750, But we despise the old graphics card that has been eliminated

bitcoin was obtained by CPU in the early days. With the continuous development of GPU speed and the emerging advantages of GPU general computing, miners graally began to use GPU instead of CPU for mining. Bitcoin mining uses SHA-256 hash operation, which will carry out a large number of 32-bit integer cyclic right shift operation. Interestingly, this algorithm operation can be implemented by a single hardware instruction in AMD GPU, while it needs three hardware instructions to simulate in NVIDIA GPU. This one alone brings an additional 1.7 times of computing efficiency advantage for AMD GPU. With this advantage, amd GPU is favored by the majority of miners

advise the landlord not to dig up if the budget is not too much!!! This money is not earned if you want to

the difficulty of bitcoin is increasing. Mining with graphics card is a race against time. The main reason is that the difficulty of mining bitcoin is graally increasing (the reason of bitcoin algorithm design). If a set of platforms can get 1 bitcoin per day according to the current difficulty, then in one month, the platforms with the same computing power will only get 0.8 bitcoins, even the top graphics cards will get 18.2 days (which can't be shut down), and the lowest second-hand hd7750 will need more than 400 (it will take 214 days to get one). Just look at this figure (this is the data in May this year, Now it's more than 18 days)

people can earn money by buying several mining machines (mining machines with dozens of top graphics cards piled together)

I hope I can help you

Running points also have something to do with the configuration of the computer. If you give full play to the performance of the graphics card, it should be about 24W

for your reference, i7 6700k + gtx1070:

4. My core is 850, and the speed is about 222m / s. It is estimated that adding 900 + can be 250 ~ ~
cgminer configuration & quot; gpu-engine" : & quot; 0-850" Try it yourself

5. Professional answer:

do you still want to mine?, In 2013, the output of the mine was halved, and the corresponding cost increased. Besides, now there are professional mining machines. You can still dig and play. Don't think about getting rich

1: mining mainly depends on the graphics card, a card is a must, mining is not n card
2: if you want to dig well, you have to have more stream processors. Mining depends on this, so the 6-series graphics card of a card is the best, 800 yuan. I recommend hd6770 or hd6850
3: the core should be as high as possible, but it should not be too high. Mining is 100% load, so you should leave some space for the graphics card. Otherwise, the life of the graphics card is not long
4: the more stream processors, the better, and the impact is very big
5: since it is used for mining, high-power graphics cards, such as hd6950, can't be avoided. The speed of mining is very high, so don't consider low-power cards, unless you just play
6: the stronger the game performance is, the faster the digging speed will be. The premise is the a card of the same series
7: compared with the graphics card, the mining speed of CPU is equal to that of snail and car, so CPU is generally OK, such as the ordinary I3 or AMD 740
8: power supply, mining graphics card is 100% load, you can choose hd6770 graphics card for 380W power supply, the mining energy efficiency ratio of this card is the highest
9: hard disk, optional, solid-state 64g is also OK, there is no requirement for hard disk in mining

mining has no requirements for video memory and bit width, just need enough stream processors. In order to take into account the game, choose 1g video memory and 128bit or 256bit.

6. Gtx500 and hd6800 / 6900 are both micro structures that have been greatly improved for Dx11. Compared with the previous generation, their subdivision surface performance has been greatly improved, and the subdivision surface performance basically represents the essence of Dx11.
first of all, the problem of gtx560 is that the gf-114 core SIMD array is a complete 8 groups, so the subdivision surface unit is also 8, because the nominal frequency is higher than gtx460, Therefore, the performance of hd6950 is 20% higher than that of gtx460. If its price is reasonable, it can completely replace gtx460.
hd6950 is a new generation of AMD's sub top single core model. It still adopts vliw4 rendering architecture, but it abandons the traditional 5D architecture and uses a more flexible 4D architecture. Therefore, the number of stream processing units in each group of SIMD is reced from 80 in hd5800 series to 64, According to the published parameters, the floating-point computing power of hd6950 has reached a terrible 2.25 tflops, and its performance is likely to surpass that of the previous generation of single core flagship GTX480. However, it is strange that in the current trend of 3D games focusing on light and shadow rendering and material optimization, the new generation of amd single core flagship is still adding texture units. Hd6950 has 88 texture units, This is a bit strange. However, it's better than nothing.
hd6970 and hd6950 are very close. The latter is obtained by shielding two groups of simds from the former. Hd6900 series greatly improves the back-end processing capability.

the rest is not detailed. Let's talk about the performance ranking:
hd6970 > hd6950 > gtx560 > gtx470 > gtx460

7. If you exclude the brush card, it may be a third-party software to rece the frequency of your graphics card. Download an overclocking software to see if you can manually adjust the frequency back to the original 800MHz

8. Top 6950, but if you haven't bought it, don't buy the 6-series card. After all, it's the last generation card. The 8-series is coming out soon, and the 6-series power consumption is not low

9. 1. The idle power consumption of the video card is 138w, while the full load power consumption is 256w (this is only the power consumption of the video card)
2. Therefore, the minimum power requirement of the video card is 500W, It also has only two standard 75W 6-pin PCI-E power interfaces for independent power supply of the graphics card.
