All About BTC, LTC, ETH mining as well as other alternative crypto currencies
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.
With less than two weeks left before the official launch date of the highly anticipated AMD Radeon RX 480 GPUs that are supposedly coming out on 29th of June with a recommended price tag of $199 USD people are getting anxious to get their hands on the hardware. The speculations are that the RX 480 will be doing great for mining Ethereum while also being quite power efficient and at the announced price it could be the killer ETH mining choice for multi-GPU mining rigs. So what could potentially make the Radeon RX 480 not so great choice for mining after all when the cards start hitting the market at the end of this month?
When AMD announced that the RX 480 will be priced at $199 USD everybody was surprised by the good news, yes, it is not top model GPU offering the highest performance on the market, but for the expected performance the price was great. Unfortunately with the upcoming release on the market we are hearing some not so good news that will make the RX 480 less attractive choice for mining and it is entirely related to the price point. It seems that the $199 USD price tag was indeed too good to be true, we are hearing from different sources that the actual end user prices will be more like 20-30% higher than that. Furthermore initially the availability of the new GPUs will most likely not be able to match the high demand that it is expected, so in the end it seems not very likely that will be able to get your hands on an RX 480 on 29th for $199 USD.
A few days ago AMD has also announced two lower-end Polaris-based models – the RX 470 and RX 460 GPUs that should be even more affordable and still manage to provide good performance (for gaming that is). What you should be more interested in however is the AMD Radeon RX 470 that is expected to be slightly cut down version of the RX 480 GPU, retaining the same PCB and 256-bit memory bus. So the chances that the RX 470 might be able to perform very similar in terms of performance for Ethereum mining like the RX 480 are pretty good and with the right price it might be even more attractive for crypto miners. However while AMD says that the RX 470 and RX 460 should be available at the same time the RX 480 launches, we expect that they will be a bit late with about a week or two on the market.
The focus of the RX 480 was mostly put on the Ethereum GPU mining, but we are still on the speculation phase and nobody knows for sure how much MHS the new GPUs will be able to provide. What you should also wonder however is how well these new video cards based on the 14nm AMD Polaris architecture will perform in other crypto currency algorithms and not just buy them because of possibly good Ethereum performance. With the recent issue with the DAO and the drop of ETH price this has become even more important and you should not forget that Ethereum will be mineable for probably up to a year more and then will be switching to PoS…
