Monero (XMR) is one of the top 15 cryptocurrencies, which has always been ahead in terms of technological innovations.
Monero will change its Proof of Work algorithm once again in order to make the network resistant to ASIC (application-specific integrated circuits) and FPGA miners.
An ASIC miner is a specific hardware specially designed for mining. They are significantly more powerful than graphics cards and CPUs, and the reason why mining for persons using CPU and graphics card is not profitable. It is therefore believed that ASICs have largely led to the centralization of mining.
Monero Hard Fork
The RandomX upgrade removes the CryptoNight which was the previously used algorithm. This will completely eliminate the ASICs from the network, and also the problem of Mining malware and botnets.
Other than that, the operation of this algorithm is optimized for the use of classic CPUs, and even the mining with graphics cards will decrease drastically, so the CPUs with RandomX will gain significantly in importance.
According to Monero Farm, the tests showed that AMD Ryzen CPUs will have an “interesting” performance advantage. Especially for the third CPU generation based on the ZEN 2 architecture. These models, boast large amounts of first, second and third level caches, practically twice as much as the first and second generation.
The Ryzen 9 3900x, which is equipped with 12 cores and 24 threads at a base clock rate of 3.8 GHz, is currently said to be the most powerful model. This CPU should achieve a hash rate of nearly 11500-12000 H/s with a consumption of approx. 150 watts at a price of over 600 dollars/euro. According to Monero Farm, the Ryzen 5 3600 offers the best price/performance ratio, with a hash rate of up to almost 6300 Hash/s and a price of less than 200 Euro/ USD.
There is still some time left before the fork happens though, as it is scheduled for block 1978433, expected on November 30th, so there is enough time for you to get acquainted with the new algorithm.
