Hello,

I'm very confused-

Should I buy Vega 64 (faster memory and more Raw computing power)

or 1080ti - overall a better card and much lower power consumption and way better at games.

or dual 1070- (lowest power consumption)


They all will cost the same.

Buy 1 1070 and wait a little to see if Vega will worth

lol issue is my machine has only 3 slots- I have one 1080ti

I thought another AMD would be nice- however, AMD 64 Vega I jumped the gun and pre-ordered  - so if I don't decide quickly I'd have it on my hands.

Don't know how to close the thread.


I just cancelled the order for AMD Vega 64

Found a 1080ti at a cheaper price point.


It may be slower but it'll have a better resale.


Thanks

You made the right choice. AMD Vega 64/56 hash rates are out. At 32-36mh, they dont even come close to the 1080ti because of power consumption. The vega's power consumption will eat up your profits.

I had same question few days ago.
Vega was not available and it seems for now vega can be bought for lolz!
1070 was only like 15 eur cheaper than 1080. I found those zotac mini 1080 with gddr5x quite interesting and cheap - 415 eur +vat seemed for me like a good deal when 1070 costs only few eur cheaper. And it has one 8 pin connector. Well, 1070 ir very nice card, but in this case I have decided to play with 1080 a bit.

If you are planning to put cards in pc case then go with two 1080ti. I have tried to put 4 evga 1080ti sc2 on asus apex motherboard but it is basically impossible to cool them. So I am using just 2 right now.

In theory if you can find motherboard where there is 2 slots between each 16x pcie slot then you can use 3 cards in big case like Define XL R2 (which has 11 pcie expansion slots) but I have not found such motherboard as triple sli and cf is long dead.

Also, in theory maybe it is possible to cool 4 wattercooled cards on such motherboard like asus apex - you need reeeaaalyyyy big case then and place to fit 4 watter coolers. But Then it would be one baddaasss video rendering rig (because gaming is using only 2 of them) and mining rig in spare time :)

mining zec
1080 = +- 500usd = `500sol
1070 = +-400usd maybe more= `400-440sol
 :D buy 7970 aka R9 280x =150usd maybe 130usd =  330sol
500usd 3x card `1Ksol =profit, volts tuning 1.081 =180-190Watts
=====
And show me a game that would not draw the old graphics card 7970(280x)

How much did you got your 1080ti for?

Just buy used rx470 8GB , you can get more return on that.

1080ti = $769-900 = 700-740 sol/s  -and that's where my math ends lol

GTX1080 gives about 570-600 sol/s at 170-180W power (OC, DV)
GTX1070 gives about 450-480 sol/s at 140-150W power (OC, DV)
And buing new GPU you get a 3 year warranity, but buing used 7970 or 280x it can be broken in few days and you will get nothing

Currently definitely 2 gtx 1070s, they get more hashrate in ZEC, Eth and probably every other algorithm, looks like vega isn't very good.

my R9 280 working at 2013? and dont broken, If buy today needs looking the state of the video card, so that there is no smell of textolite, then it is understood that it did not bask more than 85?and coolers state. Profit is achieved faster than expensive cards.But this is a personal opinion

For 900usd I can get 1980sol or 1650sol for 770usd against 740sol, Yes there are risks, but this is another
And when you buy a video card for 150usd it's easy to beat for a month and the more in the system of cards, the less time you need
But this is my personal opinion

Yes, and about the breakdown of the video card, if there are two cards 1080 to 770usd and one suddenly breaks, then 50% of the speed is lost (sol), and if for example the money in the system is 6-8 cards and 1 breaks then the loss is only 1/6 or 1/8 speeds (330sols) Something like this

Of course most of old cards are still good for mining, but do not forget about energy effeciency: new cards on 14-16nm techproccess are 1.5 times less power at the same computational power. And if you have limited electricity outlet so now it's time to change old cards to new

There is no 1.5 times decrease in consumption there. I watched the tests of cards 1070 devour 180 watts at 460sol well old 280x with the optimization of 185-190watt
So there is no difference there 1.5, but I do not argue at the drain at 1.250Volt they eat up to 250wat it so that the manufacturer does not bother with the fit of each card then at an ASIC more than 70% the card easily holds at 1.081volt frequency 1090/1600

Yes, I do not argue that a couple of years when 1080 will cost 300-400usd it will be the most

You compare not optimized 1070 with optimized 280x. In tests I reached about 210-220W power consumption from GTX1070 on Neoscrypt, but it's not optimal
To get 460sol/s from GTX1070 it could tuned at 140W consumption.
The simple example:
28 nm GTX970 gives 290 sol/s at 140W (OC, DV)
16 nm GTX1070 gives 450 sol/s at the same 140W (OC, DV)

The sense of comparing 970 and 1070 if I compare 280 and 1070, and there is no 1.5 difference in consumption, I did not see the 1070 optimization yet, without loss of production, so there is 180watts at 460oils, if the power limit is reduced, then their speed drops, so 1.5 there is not even there 28nm against 16nm
28nm R9 280x 280-300sol 200-210W at 1.250v or 1.170v standart
28nm R9 280x optimizet 330sol at 185W 1.081-1.093
16nm 1070 450sols 180w downvolt???? I do not know cost 500+usd aginist 150usd
So power consumption no big deffierence or 140-160w or 180w
This is my IMXO ;)

From the current information, 1080ti is much better.

What people fail to see is that 1080Ti costs over 40% more than a regular 1080 for only 25-30% more performance.
The comparison between 1080 and 1070 favours the 1080 in the same way.

The 1080 will ROI faster.

well, if you are confused, than buy Volkswagen.

Vega is definetely going to be a fail. Rumors about 70 MH was turned to be false..
Buy something else or wait for better AMD drivers...

i think so, its overpriced. In my town they cost more than 800 usd for vega 64.

Give this man a medal.

So you are saying I should get a 1080 ?  lol I didn't even put that up in the discussion. There is a $100 different between cheapest 1080 vs 1080ti - I never ever thought about 1080 because in mining game it's placement seems awkward. It does eat less power though. LoL

It all depends on pricing.
I got my 1080's for £400.
The Ti's were going for £675 and the 1070's for £350.
I chose the best performance for the bucks that would give me shortest ROI.

For me it's about power as well. I have 2 rigs 8 x 1060s. The entire rig draw about 750-760w so I was able to plug 2 machines into the same receptacle. My 8 x 1070 rig pulls just over 1000w so I can't really plug anything else into that receptacle. Lots of things to consider depending on someone's specific situation.

Buy 1080Ti and mine DGB skein algo...

It does 950-1000MHs.

Other options are LBC, skunk,...

It's better bang for buck than any other card

I would buy the 1080ti simply out of a density standpoint. Every pcie slot, every riser, every space used by a card is density lost. The 1080ti will provide the best density to performance ratio - it is the fastest of all these cards and can be had at a decent price point. Also if you are ever in need of money for the next 6-12ish months you will be able to easily sell off the 1080ti for a nice portion of what you paid for it - I have already done this and was shocked at how fast I got rid of them. Sold 4 1080tis within 1 hour for 90% of what I paid for them.

Don't we need to consider hash/watt? That seems to favor 1070. Or is electricity very cheap where you live?

GeForce 1070 0,326 MH/s/watt
GeForce GTX 1080 Ti 0,222 MH/s/watt
AMD's Vega 56 0,199 MH/s
Vega 64 0,131 MH/s/watt

electricity is very expensive where i live... That's why i use nvidia for mining.

I guess this chart is for Ethereum. This is only algo in witch AMD and 1070 are better than 1080 or 1080Ti.

i don't mine Ethereum.

For other algo, hash/watt is similar for all nvidia cards.

But to get the same hash rate for rig with 6x1080Ti... you need 10X1070... this means two rigs, so you have to buy second MBO, CPU, PSU,...

But if you plan to mine Ethereum, 1070 or Vega is the way to go

Don't listen to all these people, you did the right thing and got the 1080Ti, which is the best bang for the buck currently for just about all coins. Good hash rate in one card, lower power usage, and excellent resale value as it is actually very good at games what's not to like?

The price.

cheapest price for 1080ti in my town is 1000 usd, are this still worth to buy?
or buy rx470 gb mining edition for 360 usd?  ??? ??? ???

They're both pretty inflated prices. I'd personally go for the 470 as it is less inflated compared to the 1080Ti, which is simply at a ludicrous price. I would not consider mining at all with those prices unless your electrical cost is close to zero at this point. Where I live even most big box stores are below 300 and even $250 now.

how will not inflated in here if all pc store owners also doing mining  :-X
vega 64 still 850 usd, what a beautyful day  ;)

Across all variables the 1080ti is the best card currently available.  It provides best in class performance across virtually all hashing algos, has relatively low hash:watt, are generally available, provide the best power density in a rig, and will likely have the best potential resale value if/when mining takes a dive.

If you have free electricity and/or an excess of available pci slots the 1080 or 1070 are almost as good.
