AMD Radeon RX 6600 XT - hashrate on popular mining algorithms

radeon rx 6600 xt hashrate ethereum miningAMD has not yet had time to present its junior graphics card of the RDNA 2 generation - Radeon RX 6600 and Radeon RX 6600 XT, when all the technical characteristics of these video cards and prices have already become available on the network. As expected, the RX 6600 XT will have a 128-bit memory bus together with GDDR6 memory, which in terms of memory subsystem performance will be similar to the Radeon RX 580 video card currently popular in mining, which was actually released back in 2016 in the face of the RX 480. Actually, the upcoming novelty is us and compare the technical characteristics with the Radeon RX580 and try to predict the hashrate of the Radeon RX 6600XT video card based on the Ethash algorithm (Ethereum cryptocurrency) and other currently popular mining algorithms.

Technical characteristics of AMD graphics cards of different generations.

* Data for Radeon RX 6600 XT and RX 6600 may change due to used unofficial data on these video cards.

If we compare the last 3 generations of video cards from AMD, then we can note not only an improvement in technical characteristics, but also an increase in official prices for video cards. If the RX560 was sold for 99 USD in 2017, now its analogue in 2021, the RX 6600 XT, will cost 349 USD, and this is without taking into account the current market conditions, when the real prices for video cards are several times higher than the official ones. Those. only the official increase in prices for AMD video cards over the past 4 years was 250% or 3.5 times.

It is also worth noting that more modern (faster) GDDR6 memory is used in the 6000 lineup of video cards, which made it possible with a 128-bit memory bus for RX 6600 video cards to obtain a memory bus bandwidth of 256Gbit/s, which is equivalent to an RX580 video card. The width of the memory bus is exactly twice as large - 256bit.

Already thanks to this fact, the Radeon RX6600 and RX6600 XT video cards on the ETHash mining algorithm will produce a result equivalent to the RX 580 of 30-33MH/s or even a little more due to a more efficient GPU. At the same time, the GPU RX6600 XT is exactly twice as productive as the RX580, which will primarily affect the GPU dependent mining algorithms: MTP, CuckooCircle, Zhash and others.

** Predicted hash rate.

*** The RX560 video card has 4Gb video memory, which will not allow mining Ethereum cryptocurrency. Can be used in the mining of other cryptocurrencies with the Ethash mining algorithm.

Conclusion: Video cards Radeon RX 6600XT and RX 6600 for mining Ethereum cryptocurrency will not be of particular interest, primarily because of the price. a similar hash rate of 30 Mh/s is given by older and cheaper video cards: RX 580, GTX1660 Super, RTX 2060. For other mining algorithms that are more dependent on GPU performance, RX 6600 can already compete with AMD video cards of the current and previous generations, as well as the same with Nvidia video cards, tk. will be able to offer a more competitive price per hashrate.
