Drop of hashrate for Polaris cards incoming

[QuintLeo]

R9 280 can make mining

 R9 280 and 280x are better on ZEC than ETH, and have been that way for a while now.

Why are people even worried about this? The current run up in hashrate (from about 20-55TH) is ALL from polaris cards. Therefore the majority of miners are effected by this, which means that the relative distribution of coins among miners wont change.

To put it in simple terms, if everyones cards went from mining 30MH to 1MH overnight, your profitability would remain EXACTLY the same.

 I would bet that a significant part of the hashrate climb THIS WEEK has been from NVidia 1060 and 1070 cards.

 Prior to that, though, probably mostly Polaris.


 Also, keep in mind a lot of folks are using other stuff, like my own R9 290 cards....


 On the other hand, I would say it's not a big factor as the LARGE majority of ETH GPUs are probably Polaris and it will even out for those.


 I'd be more worried about the Ice Age "block time gets a LOT higher" stuff dropping rewards quite a bit.

Big news from BBT about the Claymore epoch benchmark issue. He reached out to AMD who confirmed they are aware of the issue and are working with Claymore to resolve the issue which DOES NOT affect other miners, such as SGminer. So, it appears it's an issue related to the Claymore miner and NOT the RX platform.

How much of the market do you think the Nvidia 1060/1070 make up? Probably less than 10%.

Most large farms are all running RX 470/480 since those GPUs came out about a year ago.

The R9 290/390 Hawaii series is probably in low numbers since it was originally a flagship model and probably sold in much smaller quantites than the RX series.

This guy is in over his head.

 AS I SAID, "I would say it's not a big factor as the LARGE majority of ETH GPUs are probably Polaris".

 Upon reflection though, network hashrate has approximately DOUBLED just in the last month - during which time all RX 470/480/570/580 cards have been in VERY short supply.
 Given there was still a lot of stock in the channel of NVidia 1060/1070 cards a month ago, but since those cards are now in just as short of supply as the RX cards coupled with the existing shortage of AMD cards, I believe that the amount of ETH hashrate added by NVidia cards exceeds 30% and likely is an outright majority of the hashrate added in the past month - which would put Nvidia share of TOTAL hashrate at a minimum of 15% and likely over 25%.
 I believe the NVidia share of total hashrate that was in place PRIOR to a month ago is very small, likely 2% or LESS.

 What farms were building with a year ago - or even 6 months ago - isn't a significant part of the CURRENT ETH network hashrate.

Great news. Any validations done already?

[Vann]

Only what BBT said in the comments of his video.

Yes, it works fine with SGMiner in Linux, Claymore working with AMD directly to address. Bottom line, SGMiner does not experience the issue.

He also said he was going to do a live stream last night once he was able to confirm whether what he was told about it only affecting Claymore's miner was true, but nothing yet showing any confirmation.

Claymore more or less denies

Yes, he asked for someone to send him proof of SGminer woking with a future epoch

Wolf0 also says SGminer is affected

As I said, BBT is in over his head.  Among other dumb statements in the video, he claimed the issue is because Claymore uses an asm kernel.
There's also nothing special about exchanging emails with AMD devs.  Matt, Tom, Alexander, and others are reasonably responsive.  What would be impressive is if they can tolerate a mediocre Russian programmer with an ego bigger than his mouth.

Well BBT said AMD claimed to their knowledge, only Claymore was affected. He's also not backing down from the comment he posted earlier.

SGMiner (Linux) using OpenCL 2.0 does not have the same issue after EPOCH 150+.[/quote]

[mitkala]

so it sounds like we need more info. if amd is backing that its not an issue on their end, then I might feel bad about cancelling a 90 card order in favor of Nvidia. *sigh*

If it is in the hardware, there is nothing AMD can do.

Time to put cards on the table. Bits be trippin did not come up with a video

[Juggar]

People should begin to get serious about selling their RX cards, if they haven't already. I got in while the gettin was good. Sold every RX card for over $400 and promptly bought cheap 1070's under $400.

The very day that it is fully confirmed that this is a hardware issue, essentially, non fixable I guarantee you eBay will get flooded with $300 RX cards while Nvidia will sell out that much more. You probably wont even be able to find 1050 Ti's for cheap.

Relax, he has a lot going on. Last night BBT did an excellent presentation and overview on the state of Crypto and insights of where POW mining is going. Highly worth watching even if you're not new to Crypto. He will do another video today or tomorrow that focuses on mining.

by the time we hit epoc 150 most rx cards if bough even today would have paid for themselves, gtx 1070s are price jacked up all over the place right now anyways or limits per 1 or two per order no reason to dump cards that are mining fine right now

I've been telling everyone the same thing but apparently no one can compute basic math.

"Yes lets sell our AMD gpus today for $300 which make $5/day so we can buy a $600 GPU which makes $4/day and in 6 months it will make me $0.50/day instead of the $0.33/day we would of made with the AMD gpu we've sold".

[bdiddle]

What if I sold an RX480 for $350, and bought a 1070 for $310?

Was that stupid too?
