It can be confirmed that NVIDIA is indeed making a mining card of the top-level large core of the ampere family, which is originally oriented to data center and high-performance computing. The model is named CMP 220hx. Ethereum has a computing power of about 210mhs, and the price has reached 3000 US dollars, about 20000 yuan.
From the model name and calculation force of the previous CMP HX series, this message is reliable: the Ethereum calculation forces of 30hx, 40hx, 50hx and 90hx are 26mhs, 36mhs, 45mhs and 86mhs respectively, which are all numbered by approximate values.
The calculation shows that the revenue of the mining Ethereum of RTX 3090 is about $11 a day. After adjusting the configuration, especially after the over frequency display storage, it can achieve 13-14 USD. The card is recommended to sell for 1499 dollars, and the actual price is 2500-4000 USD at present.
It will take seven months to return the book, at a maximum of $14 a day and a starting price of $3000.
CMP 220hx can account for about $17 a day, up to $19-20, and $3000 can be returned in five months if you buy it, if you have to get it.
At the same time, the power consumption of the whole card of A100 PCIe version is only 250W, while RTX 3090 is as high as 350W, which is obviously more valuable.
Moreover, it is unnecessary to use the 40Gb hbm2 memory originally matched by the A100. Only one 5GB is needed. Combined with 5120 bit bit bit width, it can still provide up to 1.6tbs development memory bandwidth, which is a mining card.
