The new AMD Radeon RX 470 GPUs are supposed to start hitting the market in a few days and since their bigger brother – the RX 480 has turned out to be a good choice for Ethereum mining, although it did not perform that good in other algorithms, people are interested in how well the RX 470 does. We got a tip from a reader that apparently has an RX 470 8GB video card in his hands already and along with the information that was sent there was also a screenshot included to show the Ethereum mining performance he is getting.

The hashrate at stock settings for the GPU shows 24.5-24.6 MHS mining with Claymore’s Dual Miner (only for ETH) and this is pretty much what the Radeon RX 480 does with the default settings. So it seems that the slightly lower number of Stream Processors in the RX 470 did not result is drop of hashrate at least for mining Ethereum (ETH) as it is a more memory intensive algorithm, do note however that it should affect performance in other more GPU-intensive algorithms. Unfortunately we don’t yet have any information regarding the performance of the RX 470 in other algorithms, but we should in a couple of days when we manage to get our hands on the new AMD video cards.

Do note however that there is a catch in this result being the same as on Radeon RX 480, the reason for the same Ethereum mining hashrate hides in the video memory. As we mentioned the results shown on the screenshot are from an 8 GB model of RX 480 that apparently has the video memory running at 8 GHz (the same as on RX 480 8GB models), so the same performance is to be expected. There will however be AMD Radeon RX 470 GPUs with 4GB of video memory where the operating frequency could vary between 6.6 GHz and 7 GHz and these should have lower performance for Ethereum. The expected hashrate in mining Ethereum is more like around 20 MHS for the 6.6 GHz video memory and about 21 MHS for the 7 GHz models.

So should you buy RX 470 8GB models with 8 GHz memory instead of RX 480 8GB models with 8 GHZ video memory if you are interested in mining Ethereum, Ethereum Classic or another crypto currency that uses ethash-based algorithm? Don’t be in a hurry to do so, because while most RX 480 cards with 8 GHz video memory could easily hit 8.8 GHz or 9 GHz with overclock it is highly likely that the RX 470 cards could be more limited in their overclock capabilities. Another thing to note is the price difference between the RX 470 and RX 480 for the 8GB models with 8 GHz video memory, if it is not big enough the 480 could remain the better choice.


The people that prefer to have full control over their Ethereum (ETH) addresses by running a local node with a full copy of the Ethereum blockchain could soon start having free space issues as the storage requirements continue to grow at a rapid rate. The Ethereum blockchain data is already getting close to 30GB in size and thanks to the Ethereum Classic (ETC) you may need to make a copy, so another 30GB of data for the ETC local wallet and blockchain. It may not be that big of an issue if you keep a single large blockchain on your computer, but people that use local crypto currency wallets usually have multiple of these and with the already huge Bitcoin (BTC) data getting close to 85GB in size as well as a few other more established older altcoins the free space required on your hard drive or let alone SSD if you use one can be over in no time…


The latest Ethereum Go client Geth version 1.4.10 named “Return of the ETH” has been just made available for download as the go-ethereum team’s DAO hard-fork implementation. It enables anyone to choose whether they would like to support the DAO hard-fork or oppose it, and take them to their blockchain of choice. On startup (on the main network) Geth will print the currently configured choice, which you can freely change with the appropriate flag at any time. If no flag is specified, the previous configuration is used. If no fork choice was ever provided, Geth will default to supporting the fork per the majority vote.

How to make your choice:
– To support the DAO hard-fork, start Geth with --support-dao-fork
– To oppose the DAO hard-fork, start Geth with --oppose-dao-fork
