Drop of hashrate for Polaris cards incoming

I didn't believe the news so I tested it myself.

The news is true.
Just tried it now on my 580 aorus, which to clarify is an 8 GB model.
My settings are:
-ubermix timings
-2195 mhz memories
-1165 mhz core
Epoch 130: 30.2 MH/s Epoch 140: 27.6 MH/s Epoch 150: 23.5 MH/s
I'd be really curious if somebody could run the test on a different cards.

R9 290 390 is good, however they do use 2 or 3 times of power compared to the RX 4 and 5 series, while dual mining.
I have several R9 390, just thinking sell them while the price is high, as they use too much fuel

[Aquazi]

can you run the benchmark for 290s?

Don't really think most of us will mind this small increase when the difficulty is doubling every 30 days and in 45 days the block times are going be double. So losing 1MH/s won't really be that much when the difficulty quadruples anyways.

So now you believe me 29-22 drop is not really a 1mh but anyway, where can i read about blocktime increase?

Thank God I went Nvidia, fully justified. Nvidia always comes out on top one way or the other.

As soon as RX cards go the 7950/7970 way (13 mhs or lower) you'll see all Nvidia stock dry up for 1050ti, 1060 and 1070.

It`s the Rx 470,480,570,580 4GB GPU`S that will be affected not the 8GB versions.

Hi Folks,

Etherium has activated the difficulty bomb
on the way to POS (will affect all cards/miners).

Maybe you can read about it here (german):

This, btw. is also the reason, why ETH will never take the place of BTC ^^

Wrong, 8GB versions are affect all the same. Better start selling your AMD cards for max profit and switch over to Nvidia, which doesn't have any issue.

What's with tongas?

[gilad215]

Damn, 8GB Models aswell? This is big..

[Mattthev]

What's with tongas?

Run the benchmark, but mostly affected are Polaris cards.

Im selling my 480's and 580's for 1070s! $400 each easy on eBay, and an excellent upgrade.

... it seems you all don´t get it:

You can´t escape the difficulty bomb !

Do your own research or cry later !

This has nothing to do with the diff bomb. This has to do with the hardware architecture of the cards. The reason it started now is because DAG size is over 2GB. In a simplified manner, you could see it as part of DAG now physically ending up on a different IC. This causes the memory controller to switch the IC it reads from more often. The larger the DAG, the bigger the part of the DAG that ends up on a different IC, the more switching it has to do.

Hats off to AMD for making trash cards once again.

Those cards are meant to be used for gaming, not mining.

GPU mining will be dead as disco in a few months.  There's no doubt about it.  It soared in the last few months because of the rapid rise in prices.  Now prices have stopped rising, the decline has started.  You can see it in whattomine.com if you've been checking it daily.  Of course it will still be marginally profitable at the end of this year if you have cheap electric but for most people, it will cost more to run your rig than it will return in profit.

The only way I can be wrong about this is if we get another rapid run up in prices which seems like a very remote possibility.  I think the majors will increase over time but at nothing like the rate needed to compensate for the increasing difficulty.

Now is a perfect time to sell your cards if you are in this as an investment.  The drop in hashrate for Polaris cards really won't make much difference.  None of the cards mining any of the coins are going to be making more than a couple of bucks a day by the end of this year and how much of that, if any will be profit will depend on your electric costs.

This aint no nostradamus prediction, it's really really plain and obvious to anyone who understands anything about how mining difficulty works.

This forum will be a lot quieter in 2018.

Yeah yeah, we've read stuff like this hundreds of times.

Right, so you know already the mining boom is about to end.  But what about all those newbies who are thinking of sinking 10s of thousands into it now as an investment?  I'm just trying to save them a lot of grief.  There has never been a worst time to start out building rigs!
