Since the RX 480 was actually a new architecture there was no way to just get back to older video drivers and have no trouble running sgminer, however it seems that the situation has improved significantly since then, though it is still not perfect for some algorithms and miners.

When the AMD Radeon RX 480 was released there was an issue with the drivers that prevented users from successfully mining many of the crypto currencies that used sgminer as the miner just crashed with an error. We are yet to see how the 4 GB models of the RX 470 will perform with Ethereum due to their lower default video memory clocks as well as how much it will be possible to overclock them. At the maximum of 8.4 GHz (2100 MHz) for the video memory we were able to get just about 25.8 MHS mining Ethereum or with other words just about 1.3 MHS more than the stock clocks hashrate. The result of the limited video memory clock is important only for Ethereum mining as the result is slower maximum hashrate.

We are not sure if it was forced because the GDDR5 memory chips from Samsung are not capable of working at higher frequencies without problem or as a safety measure so that the RX 470 turns out slower than RX 480 even when overclocked.

We are still somewhat short on options for overclocking tools for the new AMD RX series of GPUs, so this forced overclocking limit has left us disappointed. Unfortunately we ended up with up to 8.2 GHz (2050 MHz) maximum limit from AMDвЂ™s WattMan and maximum 8.4 GHz with the use of the ASUS GPU Tweak II tool. We kind of expected to be able to push the 8 GHz video memory to at least 8.8 or 9 GHz like you can on most reference design RX 480. Overclocking the Sapphire NITRO+ AMD Radeon RX 470 8GB has left us a bit disappointed. Also the default power usage of the Sapphire NITRO+ can definitely use some tweaking as it seems to be slightly higher than that of a reference design RX 480 While mining Ethereum the RX 470 wanted to keep the fans in the 30-ies as percentage or about 1300 RPM and as a result the temperature spikes above 70 degrees Celsius, so manually increasing the cooling temperature curve or setting a fixed higher percentage is a good idea to keep the GPU cooler while mining, especially if you mine coins that use more GPU intensive algorithms unlike the one used by Ethereum that is more memory dependent. What we did not like much is the default fans profile that try to keep the rotations per minute at a low value maintaining a silent operation of the GPU, but with it working at higher temperature. The Sapphire NITRO+ manages to keep just fine the GPU boosted to the maximum 1260 MHz is supports all the time, though for Ethereum mining you can lower that frequency by reducing the power limit below 100% on the Power Target as ETH does not benefit much from the higher GPU frequency and you can reduce the power usage without a hit in performance.

Again this is because of the 8 GHz video memory used on that model from Sapphire, other RX 470 cards with 4 GB come with 7 GHz or 6.6 GHz video memory and that will for sure result in a slower hashrate for Ethereum. The hashrate that the Sapphire NITRO+ AMD Radeon RX 470 8GB manages to provide out of the box for mining Ethereum is about 24.5 MHS or almost much what the reference design Radeon RX 480 manages to deliver mining ETH. The 4 GB models of RX 470 are apparently equipped with slower memory, so as far as Ethereum mining goes they will perform slower than the 8 GB NITRO+ version, though i other algorithms they may not be much slower. The only drawback is that the price of the Sapphire NITRO+ AMD Radeon RX 470 8 GB should pretty much be the same as the price of 8 GB reference design RX 480s. This faster video memory makes it interesting especially for mining Ethereum, but there are other good points to that video card as well such as the 8-pin PCI-E power connector, the good cooling solution and the 1260 MHz boost clock of the GPU.

The Sapphire NITRO+ 8GB model of RX 470 is probably the best you can get in terms of mining performance among other RX 470 offerings because it comes with memory clocked at 2000 MHz (8 GHz) or with other words the same memory frequency as the reference design RX 480 GPUs. WeвЂ™ve managed to get our hands on an AMD Radeon RX 470 video card and not just any, but the best out there вЂ“ the 8GB Sapphire NITRO+ AMD Radeon RX 470, so weвЂ™ve had to put it to a test to see how good it will perform for mining Ethereum (ETH) and other popular crypto currencies using different mining algorithms.
