1. Lightcoin calculator calculated for reference only, not necessarily real income, recommend several
mining graphics card to you, hd7990 R9 290x gold slave miner data card R9 280x
2. Three way HD5870 is similar to hd7970 now. It can dig several
bitcoins a month. A bitcoin is worth more than 1000 RMB!
3. You just start to dig bitcoin now. It's too late to enter. You may not be able to dig a bitcoin even if you start it 24 hours a month. Give up!
4. Because of the emergence of mining machine, bitcoin mining with graphics card has been basically eliminated after the middle of 2013. Take AMD hd7950 be graphics card as an example, its
computing power is 700m. Under the current difficulty, without calculating the electricity charge, it can earn 7 cents a day. At present, the price of a bitcoin is about 3700 yuan.
5. Leyte? You're going to dig ten a day? The fastest HD5830, 5970 or 7990 that can dig 10 ore per day is impossible. 10 pieces of 7990 can dig 10 ore per month. You need a 50000 miner and thousands of electricity per month
6. It's too difficult for you to enter this field now. I'm afraid that even if you start the machine 24 hours, you can't find one in a month, and the electricity consumption will be astronomical.
7. HD5970 is actually 5870x2, which is the al core flagship proct released by AMD on November 18, 2009. Although hd6990 has replaced it, and the new hd7900 series has been fully launched, its performance still can not be underestimated. Although the radon HD 5970 is a al core single card proct, its name abandons the "x2" suffix of the previous al core procts, For example, the early versions of the radon HD 3870 x2 and the radon HD 4870 x2. However, we can regard the HD 5870 as a combination of the HD 5870 and the HD 5850. The HD 5970 adopts two specifications of the HD 5870; On the other hand, the frequency of the core and video memory is 725mhz / 4000MHz. In addition, HD5970 is also the cheapest and most cost-effective mining card. Because mining mainly relies on stream processors, and its 3200 stream processors are far better than hd7970, HD5970 with 290w power consumption of 2000 yuan (2013) is more cost-effective than hd7970 with 3499 yuan (2013), and its mining capacity is also better than hd7970 with single core. HD5970 has increased in price e to the recent hot Wright coin, and it's very strong
8. According to reliable sources, AMD is expected to release its new generation of high-end graphics cards hd7850 and hd7870 on CeBIT from March 6 to 10. In terms of hardware specifications, hd7850 and hd7870 are consistent with the information we reported earlier. Hd7870 is based on 28 nm process Pitcairn XT display core. It has 1408 stream processors, 88 texture units and 24 grating units. It is equipped with 256bit wide and 2GB gddr5 video memory. The default frequency of the core / video memory is 950 / 5500mhz. Hd7850 is based on 28 nm process Pitcairn Pro display core. It has 1280 stream processors, 80 texture units and 24 grating units. It is equipped with 256bit wide, 1GB or 2GB gddr5 video memory. The default frequency of the core / video memory is 900 / 5000mhz. From the table, the performance of hd7870 is between hd6970 and hd6950, while the performance of hd7850 is between hd6870 and hd6950. There is new news about their listing prices. It is said that hd7850 (1GB) is US $139, hd7850 (2GB) is US $169 and hd7870 (2GB) is US $199—— 139 dollars, equivalent to more than 800 yuan—— 169 US dollars, equivalent to more than 1000 RMB—— 199 dollars, equivalent to more than 1200 yuan.
9. Sapphire hd7870 is a few orders of magnitude higher than gt730, but now there is no first-hand, either mine card or second-hand
a new graphics card performance ranking is attached. You can have a look at it. In addition, the same level of graphics memory has different effects
mine cards are the remaining graphics cards used by computers to calculate digital bitcoin. Due to its all-weather high load operation, the chip is likely to have some problems. Moreover, manufacturers do not guarantee this kind of graphics cards. Before buying, they should ask whether there are display problems, and whether there will be ripples, tears, or downtime when playing games. They should negotiate to buy them
