Topic: gtx 1070 1080 1080 ti why so much hate on the 1080 (Read 579 times)

 $480 is pretty high for a GTX 1070 ti - quite a few of them at the $469 price point or under on Newegg most of the time (5 right now) a couple of which are at $449 (MSI blower model and Zotac mini).
 $500 at current pricing is LOW for a 1080 there - exactly ONE listed at $499 (ASUS blower model) one at $509 one at $519 one at $529 and most at $539 or higher.
 $20 is NOT a normal difference between comparable models of 1070 ti and 1080 cards.

 Your "80% power limit" on the 1080 is for a MSI GAMING model that has a 240 "default" TDP - which is 60 watts HIGHER than almost any other 1080 ti default TDP - and the shown 180 watt draw in your picture is actually 75% TDP for THAT card, while being 100% TDP for most 1080 models.
 80% TDP on most 1080 and 1070 ti cards is 144 watts NOT 180 watts.

 As it turns out, in my testing on 2 1070 ti models to date (EVGA SC and Zotac Mini) vs 4 different 1080 models (Gigabyte 2-fan and 3-fan Windforce models, EVGA SC, and Zotac Mini), the most efficient point for ALL of the cards is right about 105 watts and they all hash at right about 460 sol/s at that point - for basically the SAME hashrate and efficiency on both sides of the question.
 The 1080 picks up more hashrate as you bump the power draw up, but not a ton faster, so it loses less efficiency as you get closer to the rated 180 watt TDP on MOST models of both cards - but even at 180 watts it's not 10% faster than a 1070 ti while SAME MODEL versions of each card tends to be 10% or more difference in price, making the ROI longer on the 1080 vs the 1070 ti *IF YOU RUN THEM AT THE SAME POWER LEVEL OR EFFICIENCY LEVEL*.

 As I already said though, if you can get a "same model" 1080 on sale for close enough to the price of the 1070 ti version, it's worthwhile - but they do NOT normally sell for a $20 difference in price for SAME MODEL cards, more commonly $50 or more price difference.

 And yes, if your power cost is low enough best efficiency is NOT best profitablity - unless you're pushing the limits on available power.


 4.7 is NOT average efficiency for a 1070 ti - that was a peak figure out of his video and as I recall was at the 60% TDP setting (106 watts) not 110 watts.
 Average is closer to 4.4-4.5 range at the BEST efficiency point, though it's not much different at the 110 watt level (still 4.3-4.4 ballpark on average in my testing).

 Trying to figure an "average" out of DSTM though is a lot tougher than EWBF, as DSTM reported hashrates bounce around a lot more from what I've seen in my testing.






 

The 1070 Ti doesn't have an average efficiency of 4.7 sol/W. That was the maximum efficiency he was able to get on Equihash at 65% power limit with 500 sols and 110 W. The ROI timeframe with that setting is one day less than the example I used.

Better efficiency per watt is not the same as better profitability. The amount of coins you mine and most of you profitability is based on your cards hash rate. Better power efficiency is irrelevant to your profitability as long as the extra wattage spent is producing more hash and therefore coins than the extra wattage is costing you in power costs.

Despite the fact that "the 1080 mines more coins" the problem with your $500 1080 GPU is that it consumes more electricity than your 1070ti. More electricity consumed, more expenses, less profit, longer ROI, etc, etc.. This is all compared to the 1070ti which has an average power consumption efficiency of 4.7 (check VoskCoin's video for reference), you will have better profits.

Funny part is no one is saying to keep the vega 64 and mine that shit lol.

I don't disklike my 1080 rig i just like my 1070s more  they mine BTG with 570 - 580 sol/s each with zm miner and i can always mine skunk if something came up.

because roughly for the same price you can take 1070ti which is better in some algo - like neoscrypt, then 1080
and in other algos the 1080 only 5-10% faster then 1070ti, while the price is 15-20% higher
1080ti has much more performance then 1080 - aprox 30-35% faster 

At $480 a 1070 Ti on Equihash has about the same ROI timeframe as a $500 1080 at 80% power limit. The 1080 mines more coins though. On other algorithms like lyrz2z the diffrence is even greater. I'd take a $500 1080 over a $480 1070 Ti any day.

Most of the time nvidia mining is all about corecount so I went and looked what's available. Not a big fan of MSI but for some reason they have good stocks right now and I needed some numbers so here we go, MSI Gaming series, €:

GPU	Cores	Price	€/Core
1050	640	164	0.26
1050ti	768	219	0.29
1063	1152	309	0.27
1066	1280	369	0.29
1070	1920	529	0.28
1070ti	2432	565	0.23
1080	2560	619	0.24
1080ti	3584	859	0.24

I actually own a fair amount of 1080s that I got for a good deal... but a 1070 Ti is a much better value across the board.

The 1080 certainly does not SUCK at mining (except on Etherium... it sucks)... but it's just not a great value.

I get what your saying. right now the gtx 1080 is going for $520 per card for evga and msi and the gtx 1070 ti / gtx 1070 go from $485 to $530 depending on place and model. I have this vega card but not sure I want to keep it and use it. There hard to get your hands on and cost a ton. Not super easy to setup being they need bios flash, special drivers, tuning isn't always the best.  Nvidia cards are simple and just work. That's one of the biggest reasons I have always used them for gaming they just work.  Also being a factory cooler board I can see the vega getting real hot. 

I have a full system with 6 gtx 1070 ti working now and I kinda want to do something else for the next system.

At current pricing (for the USA anyway), the 1080 is inferior hands down to the 1070 ti - 10% higher cost for the SAME MODEL card, but it doesn't hash 10% better and when both cards are run at their most efficient point they give almost IDENTICAL hashrate (though also almost identical efficiency).

If you can get a 1080 for $20 or less more than a "same model" 1070 ti, it's definitely worth THAT much more - but not at 10% more which is the NORM - and on rare cases of a 1080 on sale for the SAME price as a 1070 ti same-model, the 1080 wins hands-down due to higher resale value and ability to be pushed to higher hashrates if you don't need maximum efficiency.


 1080 ti - is a debate.
 It does NOT match hash/$ or hash/watt vs the 1080 or 1070 ti, be it run for efficiency OR for high hashrate - but it's close, and if you factor in total cost of a SYSTEM for the same hashrate it gets a lot closer on hash/$
 The "higher density" that allows for the use of fewer machines is a benefit that to some outweighs the small loss of efficiency.


 Most algorithms don't gain any significant benefit from a wider bus, or else the Fury and Vega would be hands-down across the board DOMINANT players in mining on everything.
 Keep in mind that the GTX 1060 has an even narrower bus, yet is quite efficient on most algorithms.


 When I talk about a "same model" card, I'm talking comparing (as an example) a EVGA SC 1070 to an EVGA SC 1070 ti to a EVGA SC 1080.
 Any other comparison is NOT a fair one, though sometimes there is no "same model" to compare TO between the various GPUs.

How much longer do u think the gtx 1070 1070 ti will make a good amount of money before the 256 bus is to small?

Because:
 - prices are not universal;
 - the 1080 has the same memory as the 1080 Ti, GDDR5X (bad for memory heavy algos such as Eth) therefore the 1070 is best for memory heavy algos while the 1080 Ti is best for compute heavy algos;
 - the 1080 is an awkward middleground between density and performance;
 - 1080 Ti has a better resale value;
 - release dates:
            1080 Ti: March 10, 2016
            1080: May 27, 2016
            1070: June 10, 2016
which you can interpret a few ways.

1080 do not like it because it has a memory of RDDR5X, this type of memory is not realy good for mining.

the 1080 (ti)s will be more worth if you ever plan/need (read: are forced) to resell

Its simply not giving enough hash power. If you compare the costs its more cost effective to get an 1070, or an 1070ti. Even the 1080ti gives more hashes per dollar. And it generally gives of alot more heat, and it draws alot more power then the 1070.

So when u see reviews they always hate on the gtx 1080 and say the 1070 and 1080 ti are better. 1070 is 400-480 and the gtx 1080 start at $520 and have a biggest bus. The 1080 ti is like 750 bucks high cost on that player.  There both gddr5x but they say the 1080 memory is bad so wouldn't the memory be bad on the 1080 ti also?  I have a vega 64 card but I want to sell it and go NVidia because u can get your hands on those cards. shit there asking over 600 for a vega card that's not worth that kind of money. Also where are the custom vega cards damn.

I just don't see how the gtx 1080 isn't a good deal with the nice over clock u can get on them.
