Incoming hashrate drop for Rx 400 and 500 cards


Can you stop commenting and provide benchmarks? launch your claymore with -benchmark xxx (where xxx is dag).
This is mine: Aorus 580 8GB, ubermix mod, 2195 vram, 1165 core.
DAG 130: 30.2 MH/s
DAG 140: 27.6 MH/s
DAG 150: 23.6 MH/s
Can you please provide benchmarks for other cards/models? Especially difference impact on Nvidia models.
edit tested a 1070 (all stock):
30.7 average at every single epoch from 130 to 190.

Do you think you'd be able to provide a benchmark with ethminer-genoil's benchmarking function as a comparison? I'd like to see if this is a claymore issue with the architecture rather than a hardware bottleneck.

Yes, sell all of your amd cards

[–]Karavusk 2 points 2 days ago 
Well I lost 0.5MH/s with my 390x and DAG 160... either way this is 100% useless since as soon as we hit DAG 160 mining Ethereum will be impossible anyway because that is arround the time when the switch to proof of stake will probably happen.
permalinkembedparent
[–]jedimstr 4 points 2 days ago* 
Well considering POS was already put off a few times before... and that the next switch will be to the hybrid POW/POS model where both are active, you'll probably still have a year or two more to go before ETH POW is fully discontinued.

Does your GTX 1070 use Micron or Samsung memory? My Samsung card only does 30.7 with an 800MHz OC on the memory.

[–]viming 1 point 1 day ago 
It doesn't affect my R9 390. Epoch 190 lowers my hashrate by ~1 at most.

[–]planetofthemapes15 10 points 2 days ago 
Claymore himself commented on this and is looking into fixes for this issue.

MinerGate apparently already fixed it: V. 6.5 – no hashrate drop after DAG epoch switch
permalinkembedparent
[–]Edratuom 3 points 1 day ago 
I think this is about a different DAG issue. They supposedly fixed the temporary hashrate drop after a DAG switch (which catch up after some hours), not the overall permanent perfomance drop that is coming related to some GPU architectures we are talking about in this thread. I wish I was wrong, because a solution to this problem would be great.

I went beyond the 160 all the way up to 190 it saying at that point 16MHs. Isn't there a possibility that this benchmark is flawed?
permalinkembed
[–]Koreenium 1 point 2 days ago* 
With each new epoch my mhs drops by 0.2 which means that with epoch 190 I would lose 12mh/s and I am currently doing 29.8 mh/s.

Seems like it is a linear extrapolation. Not sure how he came up with it.
I think we have bigger things to worry about (POS, difficulty, etc). It's not like I am going to sell all of my cards and rebuild at this point anyway.

Yeah, my cards will hit ROI at the end of July. I guess at that point what happens happens.

It says the more memory the less impact but then says 290s don't see much of a difference but Polaris cards do. Though lowest VRAM 470/480/570/580 are 4GB and so are 290s.

1080/1070 has 256, 1060 has 192..
permalinkembedparent
[–]Karavusk 2 points 2 days ago 
Yes the 290 has a GIANT GPU core, much bigger than a 1070 or 1080 with a huge 512bit memory bus. It is a high end 800$ GPU from 2012... and still beats the 1060 almost 5 years later.

This is a 390x with a huge overclock at 1300MHz core clock and 1300MHz memory clock, dont expect these numbers without a watercooler and a bit of luck.

edit2: As you can see I lost like 0.6Mh/s

It's wack, My XFX 290 gets 29 MH/s while my AMD 480s get 27 MH/s.
Although the 290 has 4 more compute units and the Memory Clock is something like 5000MHz over my OC'd 280s at 2200.
permalinkembedparent
[–]juggarjew 0 points 2 days ago 
Its also a power hungry pig compared to a 1060, btw, youd need to compare it to a 1080 if we are being far. compare high end to high end.
290's were a disaster when they came out, throttling hard. Theres a reason AMD housefire is a thing.
permalinkembedparent
[–]Karavusk 1 point 2 days ago 
Well right now it is cheap and cant compare to the 1080, I was only explaining why it has such a huge memory bus compared to other GPUs that are more expensive, newer and faster.
Of course power consumption is a different thing

[–]Robbbbbbbbb 2 points 2 days ago 
Except 1070s have 256-bit lanes and they're not affected.
permalinkembedparent
[–]Karavusk 2 points 2 days ago 
Because its about total gb/s where clockspeed is importand too. Besides that I learned that this is caused by the speed of the vram and the architecture of the GPU.

The 1060 6gb should be about 2/3 of the performance of the 1070 after both are overclocked, from what I can gather.

Thanks! If you get a chance, I'm curious to see if these benchmarks match the results from genoil ethminer's benchmark functionality.
The important questions are: - is this an issue with claymore's implementation specifically? - can it be reproduced in other miners? - if so, is there a workaround that can be implemented for Polaris?
Claymore was made aware of it and is now looking into the issue.
permalinkembedparent
[–]Koreenium 2 points 1 day ago* 
I did some rough calculating in order to find out what block number corresponds to what DAG so these numbers may not be correct. (Genoil wants block number for benchmarking)
Note that I did not use same settings, core clock, memory clock etc with genoil.
Genoil:
Epoch 130: 27.9 mh/s
Epoch 140: 26.2 mh/s

Thanks, that's interesting. I'd be really curious to see if we see the same degradation as you posted on the GTX 1060's or if it's also degradation-less. I'll be able to check in a day or two (i have some 1060's sitting in their boxes at the moment).

[–]shaft_of_gold 1 point 1 day ago 
There were no issues on the 1060 6gb or 1070, ie: should be fine if you have 6gb+ ram on an nvidia board.
The hashrate slow down on the AMD's seems to be related to dag size, but it could be a programming issue with the miners and how they work out hashrate when benchmarking? Guessing here though.
Either way, still seems that you need the same amount of gpu ram as the size of the DAG file regardless of if it's an AMD or nvidia card.
Almost at DAG 130 now, so 50ish more epochs to go before 3gb cards start failing. 3-6 months I guess?

[–]PhoBoChai 2 points 2 days ago 
This article is misleading since it implies a weakness in Polaris, but it's actually about memory capacity since lots of miners went with 4GB variants to save $$.
It's the death of 3 and 4GB GPUs for mining ETH as DAG size grows above their memory capacity. As data is stream in memory, it takes more cycles to generate the same output basically so performance will drop further as DAG size grows.
These GPUs have to be switched over to Equihash where it's not memory sensitive.
8GB GPUs can carry on as usual for a long time.
permalinkembed
[–]ep1939 14 points 2 days ago 
No, even 8gb is affected, I run the benchmark myself (posted the results below).
I'm interested tho how's 290/390s, furys and nvidia cards not affected.
permalinkembedparent
[–]GuessWhat_InTheButt 2 points 2 days ago* 
It's because it is about memory bandwith, not size.
permalinkembedparent
[–]ep1939 2 points 2 days ago* 
Still, I don't understand how it would affect less Nvidia and Fury/290 cards.
permalinkembedparent

[–]Karavusk 3 points 2 days ago 
The memory bus AND the clock speed together make the actual speed in gb/s for mining. You need to consider both.
But yes I expected the 1060 to tank hard because of this too but for some reason it doesnt seem like it will be effected by much... which doesnt make any senese. Probably some architecture stuff that Nvidia included. They do compress stuff way better than RX GPUs in their vram so maybe that is causing it to need less vram and still be fast enough
390x vs 480, look at the gb/s
permalinkembedparent
[–]juggarjew 3 points 2 days ago 
Yes, since maxwell I believe nvidia has been strong on memory compression. That's why on average nvidia cards have a smaller memory bus. This is most welcome news for nvidia folks, in the coming months we might even see 1060 and 1070 sell out fully like RX cards.
permalinkembedparent
[–]Karavusk 2 points 2 days ago 
AMD seems to improved that by a lot with Vega though (which will take some time to come out). I still dont think that they will fully sell out (they currently kinda are though, atleast the cheaper ones) because now AMD and Nvidia had some time to react
permalinkembedparent
[–]PhoBoChai 2 points 2 days ago 
1060 is 192 bit and even less bandwidth.
Wait and see how it turns out, since in theory, DAG size is to stress memory capacity & latency.
