1070 sli? 4K!?

[Imaginary Friend]

So i wonder if i sli two 1070 will i be able to play in 4K?

Consider getting one powerful card instead of two mediocre ones. SLI causes too many headaches with drivers and games most of the time aren't optimized for it.

So i should buy 1080 instead?

wait for the 1070 benchmarks

Inter better to get one better card rather then to SLI 2 lower tier cards, Mosley because SLI is t fully supported by a lot of games and can just be a bad experience 

[henkka_scorpio]

I also say go for the gtx 1080 then later you can get another one, but if you get 1070 sli you cant get more of them.

[Simon771]

At this point we don't know how this new SLI will work in real games.

GTX 1070 is around 70% of what 1080 is, so if you get 2 of them in SLI, theoreticly they should be 40% faster.

But will they?

 

No idea at this point.

Its looking like the 1070 in SLI will beat out the 1080 pretty handily for not a lot of extra money. I was faced with the same decision with the 970/980 and there is no doubt that the 2x 970 is the vastly superior option for most of the life of the cards. There have been quite a few games this year that didn't have good SLI support and still don't and probably wont ever have support but we don't really know if this is going to continue or not. In the past its only been 1-2 games a year and not normally ones that matter too much (games like Formula 1 which runs well on a single 970) but its been big budget games with needs for dual GPUs to perform at their best.

 

Faced with the same dilema and coming from 970 SLI I would have recommended it 6 months ago, it had been a great experience (especially compared to how awful 7970 crossfire was). But this year I am wavering, its not been good for SLI.

A lot of terrible advice in this thread.

 

Everyone loves to parrot "one superior GPU > two mediocre GPUs" because they heard someone say it once to someone in relation to buying two 760s instead of one 780. In that example it is a bad idea.

 

It isn't here. The 1080 and 1070 are both GP104. They both have 8GB vram, they both are going to be within a whisker of eachother in terms of performance. They are, however, going to be lightyears apart in terms of price.

 

It always makes more sense to SLI two of the cut down version of a GPU than get one of that exact same but fully enabled GPU from a budget perspective.

 

This is why it always made more sense to get two 980 Tis instead of a Titan X, two 970s instead of a 980, two Furies instead of a Fury X (although the Fury X's price itself was actually quite reasonable for what it was), two 290s instead of a 290X, two 780s instead of a 780 Ti...

 

Just as an example, the 970 was £150 cheaper than the 980 at launch. This means that SLI 970s was £300 cheaper than the near identically performing 980 SLI. The 980 Ti was around £500, the Titan X was around £800. So even though SLI with either one of these would be pretty much the same thing, SLI'd 980 Tis could have been £600 cheaper than the SLI'd Titan Xs. You could buy another 980 Ti for that. In fact returning to the 970s, you also could buy a third 970 for the same cost as the two 980s. It's just a shame that 3-way SLI never really developed because if it did that would have been epic. Maybe MultiGPU in Dx12 will change this in the future.

 

I will also say that the vast vast majority of people who claim that SLI has issues and is a bad experience have never actually used it, and are once again merely parroting things they've heard.

As someone with SLI right now typing on the SLI machine

Sli is mostly fine, but it only makes sense when you are pretty much at the top of the gfx card chain and its just not enough for you. 

 

it makes 0 sense for a lower end SKU and you are hurting yourself because as it has been said SLI isnt dependable.

 

At times you will get 85-90% performance increase (like bf3/4) 

 

other times you will get 10-30%

 

other times you will get nothing (Batman AK)

 

and in rare cases it will actually hurt your performance (Watch_Dogs)

 

The single more powerful card is ALWAYS going to be more consistent in how it performs  between games. 

 

that being said take battlefield for example ...if you are pumping out 200 FPS in bf4 on a 1070 ..is a 1080 going to give you 400? ...I very much doubt it 

 

That being said with 2 1070s...if it scales like it did with my 680s, you are looking at high 300s potentially  where is I would expect maybe 350 on the 1080 

 

Again these are all just theoretical numbers to make a point, as you can see in my BF example the 1070s would be a better route. 

 

 

but as I mentioned before thats Just with BF, you boot up BMAK or Dead rising 3 and you will see 0 performance gain and the 1080 will do you better. 

Most games will offer some kinda reasonable FPS boost in SLI though and imo the 1070 is a high enough card to justify SLIing since its probably gonna be close enough to the 1080 in terms of performance, but until we start seeing more hard data this is speculation that the 1080 and 1070 are very close.

1070 will be way worse than a 980 TI after seeing 1080 benchmarks vs that card the 1080 is only 2-5 faster than a 980 TI.

play 4k what?

playing 4k minecraft or dota will be fine

you can play 4k world of warcraft on 280x

what's "play" is launching the game without crash considered playing it?

playing metro 2033 LL - probably not

People in this forum consider "play" to be "run at max graphics settings with 8x MSAA". For some reason they hold 4K to a much higher standard in the graphical options than they would any other resolution. Which is absurd, because the diminish returns for going very high to ultra are so much greater when you have just a much bigger pixel density.

Easily.

resolution > detail level any day for me, as long as the game games textures actually scale well with resolution

Really? Why don't you read it again. How can he possibly know this without benchmarks?

 

 

How can I know what? That they are going to both be GP104? Nvidia have said. They both have 8GB vram? Again, Nvidia said. That they are going to be different prices? Again, straight from Nvidia. That there is going to be a relatively small performance difference? They're the same chip, just binned differently. Look at every other example of two cards with the same exact chip, but one has some CUDA cores or stream processors disabled and look at the performance difference. You can almost always make the difference back with an overclock.

Small performance difference 33% is small ?
