The 30hx is an Nvidia graphics card, a product line of graphics cards launched by Nvidia for cryptocurrency mining. In addition to this graphics card, has 1408 CUDA cores, is 6GB GDDR6 memory, this graphics card its appearance using dual fan design, there is a single eight-pin auxiliary power supply. However, this graphics card is mainly used for mining and is called a miner's graphics card, so it removes the video output interface, so that the use of this graphics card can be more focused on mining. The 30HX graphics card brands available on the market are ASUS/COLORFUL/nvidia, with slightly different appearances, but all are dual fans, and hashrate can reach 31-32mhs.►Nvidia 30HX is a 6GB memory, 2Q 2021 professional mining graphics card, better heat dissipation, stable mining performance, hashrate can reach 31-32mhs. ►Nvidia GTX 1660s is also 6GB video memory, also has a better mining performance, hashrate can also reach 32mhs, heat dissipation is also better, but because this is a game graphics card, so in addition to mining, it can also be used to assemble a computer, office or gaming functions. So compared to the 30HX, the 1660s is priced slightly higher. ► RX 580/590 is 8GB video memory, has been in circulation in the market for 5/6 years, due to the use of longer years, GPU performance has been reduced, heat resistance performance declined, hashrate can only reach 27-29mhs. Although this, because its price is much cheaper compared to 30HX and 1660S, so there will also be people keen to use 580 8G for ETH mining.
