Even before the start of sales of the Radeon RX 67000 XT video card (March 18, 2021), the first tests of this video card in cryptocurrency mining have already appeared on the Internet. As expected, the video card was checked for the issued hash rate using the Ethash algorithm (Ethereum cryptocurrency) and the KawPow algorithm (RavenCoin cryptocurrency). Both of these algorithms are sensitive to the memory subsystem of video cards. The Radeon RX 6700 XT has a 192-bit memory bus instead of the 256-bit one in the previous model Radeon RX 5700 XT, therefore the new product showed not the most impressive results in the mining of these cryptocurrencies.
Hashrate of AMD Radeon RX 6700 XT video card in Ethereum mining
ETHash: 43,5 MH/s
Hashrate of AMD Radeon RX 6700 XT video card in Ravencoin mining
KawPow: 22,7Mh/s
The test of the video card was carried out on stock settings, so you can add 10-20% to the results shown by using overclocking from memory.
If we compare the results obtained, then the hashrate of the RX 6700 XT video card is very close to the results of the RTX 3060, which also has GDDR6 memory and a 192-bit memory bus. Recall that Nvidia RTX 3060 has a mining lock due to which the hash rate of this video card on the Ethash algorithm immediately after mining is turned on shows 45-50Mh/s and after a few seconds it drops exactly twice to 22-25Mh/s. For RavenCoin, the limit set by Nvidia does not work, so the RTX 3060 on the KawPow algorithm shows a similar performance at 22MH/s.
