Hmmm ...

So similar running costs and performance to the 1080 Ti ... but a lot cheaper to buy! Definitely sounds like a good choice.

After running for a while RX Vega drops from slightly above 2000H/s to 1700-1800, not sure if it's heat soaking or power management but temperature does not look high and I would expect power management to kick in sooner and raising power in Wattman rises hashrate a bit but nowhere near the initial 2000. Shutting down miner and restarting it's back to 2000. I have lowered settings a bit and now it's running in 1930-50 range at 250W and so far does not seem to drop hashrate over time.

Also tried the miner on my RX4**/5** rig but it does not work,:( it's been designed specifically for Vega cards. Need to have a look around if there is something better than the one that comes with NiceHash for RX4**/5** cards.

Edit: I think I found when Vega drops hashrate. If I switch off monitor it keeps mining at the full hashrate, when I switch it on it drops to 1500 temporarily, then goes to 1700 but never fully recovers to 1950, only way is to restart miner.

Running cost about the same as Ti, the performance depends how you look at it, RX is nothing special at stock but with the right driver, settings and miner it excels in one algorithm - CryptoNight giving ~2000H/s compared to 750-900 for Ti. It's very profitable to mine CryptoNight at the moment, it had a nice bump last Friday/Saturday on NiceHash but has been dropping since, still 30% more than it was before the bump and even at previous levels it would still be £3+ per day so better than Ti most of the time. But it's just 1 algorithm so in that regard it's kind of similar to ASIC, if it becomes unprofitable other algorithms will not earn much but unlike ASIC it will still bring in some money and will still have value as gaming or VR card. Then again if you look at RX480 cards they were doing very well on Ether mining but now that it is not that great it's still profitable and they are also earning more with CryptoNight.

I have been spending most of the day today trying to get Vega to work with one of existing rigs as for the testing I used motherboard that usually runs 2x Ti's so my Ti's was not earning any money. I tried adding it to my AMD rig and you need to modify batch file to tell it which opencl list the card is on and what device number. It was working but just at the basic hashrate 800-1100H/s which was no good. Then I tried it on my Ti rig with extra power supply and while it works on NiceJHash miner at the basic rate I cannot figure out which opencl list is it is on and what device ID so cannot get it to work it that way.

On another news looks like x2 cancellation first raised BTC price, then it went down with BCH gaining almost 40%

This is why I've started to favour nVidia cards more. There always seems to be one problem or another with the AMD cards, like system crashes, temperamental drivers, buggy or badly designed GPU software. By contrast, the 1080s have been trouble free for me, and (apart from a few simple OC tweaks in the GPU software) pretty much plug and play.



And yeah, BCH is really rocketing (now that I have none!). I think ultimately the price will continue to rise but I think it's likely there'll be a big sell off before too long, crashing the price back below $1000 before it can climb further. The rise is unsustainably steep at present. The moment a majority of traders start to sell to take a profit, it'll trigger a price 'correction' avalanche, falling until it hits the 'support level, which I would guess is somewhere around $600-$800. I might buy back in of it does.

After some juggling around I finally got all my cards plugged in and working. Vega is together with 2x RX 480 cards on the motherboard that used to run Ti's and Ti's have been moved to my old PC which had 2x RX 480 in it before. Each card running on it's own instance of miner.

Baikal Giant X10 is earning a lot at the moment on quark algorithm, but I guess it's in the same boat like D3 and x11 with relatively small network if many new miners jump in it will go down very quickly. At least Giant x10 can run several algorithms unlike D3 which only does X11.

S9 profitability has jumped as well, lloks like many try o mine Bitcoin Cash now that price have gone up.

That'll explain why my S9 keeps getting rented lately, even though I'm continuously nudging the price up. I need to do the maths again and figure out what it should be priced at now.

Just for interest contacted Baikal about Giant X10 as I am not looking to spend more money at this point. Here is their response:
