RX series mining and HD series mining

1. 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

2. Sapphire R Series graphics card and HD graphics card which performance depends on the specific model, r9270 and 370 is hd7850 vest, the three performance is basically the same. The performance of the latest rx560 graphics card is also lower than that of hd7970. The performance of rx480 / 580 is also lower than that of hd7990. Performance cannot be judged by model alone.

3. It's just that the name has been changed, and the technical parameters are basically evolving according to the original rhythm
because the HD series will soon come to an end after being renamed, and such super long names as hd7450 are easy to cause confusion. Because the name of hd9800 can be found no matter how big it is. You should know that 9800 has been used when there is no HD prefix, and NVIDIA has also used the name of 86009600. According to the rhythm, you can't tell which brand and which model the name is
it seems that R-Series is launched to re integrate the proct line.

4. There are many types of AMD graphics cards, and they are also messy. There are about HD, RX and R models, of which R series has R5, R7 and R9

the HD series of graphics cards were relatively early, and now it is an outdated model. For example, R9 is high-end, R7 is medium, and R5 is low-end. For example, for the R9 290x graphics card, 2 represents the algebra of the graphics card, 9 represents positioning, and 0 represents hierarchical performance

there is also a RX series with the largest number at present, and the model number is prefix + 3 digits + after. For example, RX + 450 + D. The hundreds are algebra, the tens represent level, and the ones represent version

the following letters are generally common: x2 represents the al chip graphics card, X represents the complete core, while boost, XT and pro are enhanced versions respectively, but D should pay attention to castrated graphics card.

5.

HD is the earliest, and R7 and R9 replace HD. Rx is the latest. In terms of performance, RX has been improved by one level. For example, r9270 (compared with n card, which is about the same level as GTX 950) is more than one level worse than rx470 (compared with n card, which is about the same level as GTX 970)

HD is the earliest, and R7 and R9 replace HD. Rx is the latest. In terms of performance, RX has been improved by one level. For example, r9270 (compared with n card, it is about the same level as GTX 950) is more than one level worse than rx470 (compared with n card, it is about the same level as GTX 970)

RX this is the positioning, and the last three digits are the model. R7 represents the middle and low-end model, R9 represents the middle and high-end model. The first digit of the last three digits is the code, which is used to distinguish the third generation. What is really decisive is the second digit of the last three digits. The larger the number, the higher the high-end, and the stronger with X than without X

1. Numbers represent different

HD series graphics cards are mainly based on the numbers on the back. Different numbers represent different performance and price

take hd7950 as an example, first of all, the number 7 represents the seventh generation of AMD graphics card. Generally, the latest generation has made progress in architecture, and the performance will be better. The following 9 represents the performance positioning in the seventh generation graphics card. 8 and 9 belong to high-end graphics card, degree 6 and 7 belong to middle end graphics card, and 5 and below belong to low-end graphics card

Second, different performance

the most important thing to distinguish performance is to ask the second number, 9 means high-end graphics card, if it is 4 means low-end graphics card. After reading the second number, look at the first one, because the performance and power consumption of the new graphics card will be improved. For example, hd7870 is better than hd6970

three letters represent different

HD starts with AMD's graphics card, such as hd7850, and the mobile version of notebook's graphics card is represented by m at the end, such as hdxxx0m. The former represents independent graphics card, and the latter has M representing notebook's graphics card

extension information:

principle and mode

the graphics card is inserted into the expansion slot on the motherboard (generally PCI-E slot, before there were AGP, PCI, ISA slots). It is mainly responsible for converting the display signal sent by the host computer to the general electrical signal, so that the display can understand what the personal computer is asking it to do. Graphics card is mainly composed of graphics card motherboard, display chip, display memory, radiator (radiator, fan) and other parts

the main chip of the graphics card is called "video chipset" (also called GPU or Vpu, graphics processor or visual processor), which is the main processing unit of the graphics card. There is also a memory similar to computer memory on the graphics card, which is called "display memory" for short

in the early stage, the graphics card was only a simple one, which only played the role of signal conversion; We generally use graphics card with 3D picture operation and graphics acceleration function, so it is also called "graphics acceleration card" or "3D acceleration card". The earliest graphics card on PC is MDA and CGA two-dimensional acceleration card on 5150 personal computer launched by IBM in 1981

7. R series is a relatively old series. RX 200 and 300 series have been manufactured in 28nm process since 2013. Most of them are vest cards, as well as the classic 290x, 390x, R9 and fury series
Rx is a new series, which is made by 14nm process and the fourth generation architecture of GCN, with higher efficiency and lower calorific power consumption. It has been greatly improved.

8. HD series of AMD graphics card is the last two generations of graphics card code, the last two generations of independent graphics card are using R7, R9, RX series naming method.

9. The RX series is the latest model
R9 is old. Now install a new graphics card is sure to choose RX series.

10. Rx580 is 50% - 60% stronger than the strongest hd6990 (two 6970) of hd6000 series
at that time
hd6990 can match gtx770 or R9 280 at most in the Games supporting al core GPU
