Apparently, a cryptocurrency mining company is interested in Nvidia’s CMP cards. Recently, Hut 8 Mining Corp. invested $30 million in an order that is expected to start shipping in May. Specifically, the Nvidia CMP 40HX mining card performance might satisfy the miners who currently have to go for hacks to use Nvidia RTX 3060.
When Nvidia disclosed that it would be releasing a CMP line of silicon exclusively made for mining purposes, the listed specifications were a little disappointing. One of these is the three-month warranty given with few AIB cards based on the Nvidia CMP 30HX chip. It seems that Nvidia had created custom silicon rather than relying on insufficient consumer chips from the production lines to transform them into cryptocurrency mining processors.
As per an Asus photo of internal testing on one of these cards, Nvidia’s AIB partners can enhance their performance. When it comes to the CMP 40HX mining card, the listed hash rate for Ethereum mining algorithms is 36 MH per second. While Asus could hit 43 MH per second – a 20% increase over the claimed performance.
Asus has gained this speed by optimizing the memory clock and timings since Ethereum mining algorithms are sensitive to memory bandwidth and latency and taking a little advantage from a higher core clock. Actually, lowering the clock can improve power efficiency to a certain degree, thus the Asus CMP 40HX cards you see in the screenshot given above can achieve a power consumption of 134-135, which is lower than the TDP of 185 watts.
One exciting thing about these results is that they almost match the hash rates obtained with an Nvidia RTX 3060 when using a leaked driver that can bypass the company’s mining limiter. We can expect that it will result in more purchasing of CMP 40HX by miners for $699 while the CMP 30HX will be retailed for $599. In both cases, Nvidia hopes to make a minimum of $150 million on orders of CMP cards placed during the first quarter of the year going on.
