Preliminary review: GeForce GTX 1080 2-way SLI

by Hilbert Hagedoorn on: 06/06/2016 02:42 PM | source: | 44 comment(s)

We look at the GeForce GTX 1080 setup in SLI mode. In this article we'll zoom in at Ultra HD gaming performance as that's where the cookie seems to crumble. Driver issues prohibit us to test all game titles, so this will be a preliminary article until Nvidia outs a proper working SLI driver. Join us in this review where we'll once again look at everything.

You can read the article here.

These are indeed very weird results. It seems 1080SLI scaling has a problem at lower resolutions (1080p/1440p) yet at 4K, scales very well. Will be interesting to see how things go with the next driver.

FYI - i'm running 2x 1080's in SLI + i7 6850K + 32GB Kingston HyperX Savage 2400mhz. I am not overclocking any of those components at the moment and i managed to get 24,379 in Firestrike and 16,468 in Firestrike Extreme and 9050 in Firestrike Ultra. So even though my 6850K is running at 3.6ghz while ur 5960X is running at 4.4ghz, i still managed a higher result, Hilbert. Very strange indeed.

Thanks for the review, and yes, should be alot better when newer drivers are out, from here on out, the performance of the card's in general wether sli or not will continue to improve, it will just get better from here on out, so it will take sometime, :)

Are you running reference clocks or tweaked ? Also, did you see any SLI scaling with any of the DX12 titles ? + what driver do you run ?

I imagine the CPU is going to start becoming a huge bottleneck at 1080/1440p. In fact there are probably going to start being areas where it's a bottleneck even at 4K.

When the Ti and Vega come out, the scaling is going be all over the place.

I'm using reference clocks for both GPU's and the CPU and RAM with geforce driver 368.25. I haven't tested any DX12 titles yet.

I'm also using this custom EVGA SLI Bridge since that one allows me to connect all 4 of the bridge sockets.
