AMD GPU Shortages May Continue Longer Than Expected

We are hearing information from different sources that AMD may have more serious issues with supplying enough of its Radeon RX 500 series of GPUs on the market for the next couple of months. It is not all about the increased demand from crypto miners as it seems that that the company may be experiencing some other issues that are causing it to not be able to produce enough GPUs to cover the demand. Looking at Ethereum’s hashrate and difficulty data however does not yet show a significant slowdown in growth, but the reason for that could easily be the move of existing mining power from other crypto coins to ETH.

With AMD GPUs hard to get for a while now miners are looking for alternatives that are good for Ethereum mining and while Nvidia GPUs are generally more expensive, there are some that are interesting for ETH mining. We are talking about the GTX 1070 that can do 25 MHS stock and 30 MHS or even a bit more after some memory overclocking and it can do it with a reduced TDP. As a result some miners have started looking at GTX 1070 as a solution to use for new mining rigs, again it might be more expensive, but with the high profitability mining now with a more expensive GPU than waiting to possibly secure some cheaper AMD cards in some days or even weeks…

Other more powerful GPUs from Nvidia are not so great for mining Ethereum due to the use of GDDR5X video memory instead of GDDR5 that is found on the GTX 1070. The GDDR5X memory is faster in terms of clock speed and offers more bandwidth, but apparently uses less aggressive timings and as a result is not much faster than the “slower” GDDR5 memory. As a result if you are looking at GTX 1080 or GTX 1080 Ti for Ethereum mining their price/performance ratio is really not attractive at all as far as Ethereum mining goes. Nvidia on the other hand is faster on ZEC and many other algorithms, but then again people are currently crazy about ETH. So do your math and think about it and don’t overthrow the GTX 1070 as a good option for Ethereum mining.

The reason why NVIDIA cards are shit for etherium is only because nobody cared to update Genoil’s CUDA code that was optimized for Maxwell. Pascal is a bit different. When opts are done, Pascal cards will beat all AMD cards down the line.

@djeZo And when optimizations will be done? Probably never….

Yeah don’t get your hopes up for Nvidia

Yeah not drinking that koolaid. It’s fun to think of possibilities, but claymore has his own Nvidia miner and it has similar results to genoils. Nvidia doesn’t have the bus width with gddr5 and gddr5x is too loose. Nvidia is a terrible idea at the moment unless you want to mine ZEC for half as much as a 480 is making on eth+sia or just straight up sia and make just as much.

Ethereum (dagger) is a very mature and large reaching coin. If there was a way to drastically increase performance it would’ve happened and people would pay a lot for it.

So is there any way to mod the 1080 Ti bios with faster timings?
