My Brain Hurts - Which GPU?

[iEKOS]

Hi guys.

I'm getting back into mining has a side hobby and I need to make a decision and hope you guys can help.

I have a choice on either:

5x 4GB Sapphire Radeon RX 570 NITRO+ @ £280
or
4x 8GB MSI Radeon RX 580 GAMING X @ £300

I've been reading soo much my brain hurts.

Some say go for the Sapphire RX 570 due to value and dual mining.  And some say go 8GB MSI RX 580 due to the future proofing element and more RAM.

I will not have electricity costs at the office I will be renting.

If it helps, I am planing to use Simple Mining / Multipool.

Please help me decide.

Thank you.

I'd say RX570.
Dual mining is actually not a bad thing. The cost of the RX570 is lower too. And for now, proofing isn't as important. I'd say go for the RX570.

I have both cards. The Sapphire Nitro+ RX 570 4GB is a good card. It overclocks well for a 570 and runs cool. It uses a bit more power than my other 570's which are Powercolor Red Dragon's. With a simple 'one click timing patch' using Polaris Bios Editor' v1.62 from jaschaknack and a 1200 MHz core clock and 2020 MHz on the memory, I get ~28.5 MH/s and 740 MH/s dual mining DCR.

The advantage of the RX 580's over the 570's is the 580's uses faster memory, 8,000 MHz for the RX 580 vs 7,000 MHz for the RX 570, which can overclock higher. The RX 580's have better dual mining performance as well. The MSI Gaming X RX 580 8GB is a good card, but I like the Sapphire Nitro+ RX 580's better. They Sapphire Nitro+ RX 580's run cooler than the MSI Gaming X RX 580 and I can overclock the memory to 2200-2250 MHz on the Sapphire vs 2100-2120 on the MSI. With the MSI I get 29.5 MH/s on ETH and 860 MH/s DCR dual mining.

My brain hurts even more lol

The Sapphire Nitro+ RX 580 was an option but its out of my budget (another £50 per card).

It has to be one of the two above.  Remember, I can get 5x Sapphire Nitro+ RX570 or 4x MSI RX580.  Unless the 8GB on the RX580 is going to be advantagous in the future, my heart is pushing to The Sapphire.

Is the 8GB really going to help in the next one/two years?  Its if and butts.

Sigh..

R580 Nitro+ can reach 31MH/s, but its very very power hungry. You should better to go with P106-100. 25.8 Mh/ 85-90W at wall.

Power is not an issue sir

Not any real performance gain from 4 GB or 8 GB. The main benefit is the RX 580's overclock better and have better dual mining performance, but they also use about ~40 W more power than the 570's. It really depends on whether dual mining is important to you and what your power costs are. As far as the Dag file, it won't reach 4 GB until 2020 and ETH will be POS only by then, so it's not really an issue. The MSI's have a 3-year warranty compared to two years for the Sapphire cards. I get RX 580's for $30-$40 more than RX 570's. As newer cards have more memory, the resale value on on a 8GB card will be slightly better than the 4 GB in the future, so the 8 GB cards will hold their value better.

i prefer the 570's. my 580's consume much more power and generate much more heat for minimal performance gains. i agree with the numbers above, but you're basically getting 2 mh/s for a ton more heat and 50% more power consumption.

Forget about AMD and buy Nvidia cards - with the Lyra2rev2 hash you can get with them you can make a killing on Vertcoin or sometimes Monacoin - and they are so much better than AMD for ETH mining. My 1070s get 32mh/s at 150W per card. I am mining vertcoin now with 4 x 1070s and 5 x 1060s and getting close to 300mh/s. Plus you get amazing efficiency on all the equihash coins. I don't know why people bother with AMD cards. Is it just price? Or is it because you don't care about electricity prices?

I wont have any electricity costs with the office I'm about to rent dude, so thats not the problem..

Also, the 1070 will cost me:  £360 compared to £300 for 5mh/s extra maybe.

5x 4GB Sapphire Radeon RX 570 NITRO+ @ £280

RX570 will be better. I have 30pcs RX570 4Gb Powercolor and it was very nice gpu.
Timing + OC will give to you 170mh/s at ETH & 5000mh/s at DCR in dual mode. Power consumption 6 gpu rig is about 1100W from the wall.

[supersaltybaked]

I've got 4 PNY 1070's and I'm dual mining ETH and SIA (conservatively)

temps between 55-67

120m/h
1190k/h

[Phantoms001]

I like the idea of more cards vs larger cards.  2 cards always hash better than 1.  I really don't see a huge difference between the 570 and 580 in hashrate.  For example, at this second, running stock my 480 (8g) is getting 1.07 a day mining EXP 24 mh/s but my 570 (4g) is getting .97 a day 21 mh/s, 10 cent difference.   I'd want the extra card, I think it makes you more in the long run.   

[Johny101010]

If u mine just eth:
5X570 x 26 MHS = 130 MHS
4X580 x 30MHS = 120 MHS
130>120
Since your budget is indifferent get the 130 + extra card.
This is the easiest math problem ever.

[juanichiloco]

Yes i'd also go for the 5x RX570 as you'll get more hashing power.

My rig has 4xRX570 and performance has been good so far, there the ASUS expedition OC model though so a bit lower hashrate but power usage is good. Mining Eth they get 27mh/s each using a powersaving rom.

Consider buying coins rather than mine. Mining is only profitable if speculation is hugely profitable. I have been mining for 2 years now. Started with ethereum in November 2015 and I have always sold my coins and buy new hardware to expand. I have an impressive 6 rigs setup now with total of 38 x 1070.

If I just bought 390 Eth when I bought my first two rigs I would have had x4 more now.

[Etherion]

And alot more sleep

[crocozino]

take nvidia instead, if you take gtx1070 you'll have quite wider choice of coins you may mine. not eth only
even on whattomine eth is not the best choice now and it was not the best for the long time now
seriously consider  nvidia rig, it will give you more flexibility

A difference of 20 pounds is not a lot of money. I recommend taking the RX 580. Double extraction on the GPU is higher than the RX on the 570 and I think the GPU is more promising for mining. Today you will save 100 pounds, and tomorrow you will lose £ 1,000 because it will be spent on modernization of equipment.

I support that opinion completely and i have to add that the resell value is bigger than on the 570.
If im you ill go for the 580 for sure.
