GTX 1070 & 1080

[epixoip]

One of you was going to start this thread anyway, so I figured I'd be the one to do it. 

NVIDIA GeForce GTX 1080

2560 cores
1607 MHz base clock, 1733 MHz boost clock
8GB GDDR5X
180W, 1x 8pin power
94C max temp

The GTX 1080 reference design (aka "Founders Edition") will be available on May 27 for $699. It will be available from ASUS, Colorful, EVGA, Gainward, Galaxy, Gigabyte, Innovision 3D, MSI, NVIDIA. Palit, PNY and Zotac. The reference design allegedly supports "crazy overclocking, over 2 GHz clocks." OEM designs are expected to start at $599.

A demo during the official announcement showed the reference card running at 2114 Mhz; at this frequency, it's very possible this card may be up to 15% faster than the Titan X. Of course we don't yet know if any OEM design coolers can support these clockrates, or even if the reference cooler can support these clockrates while running Hashcat (many are saying that the framerate in the aforementioned demo was locked at 60 Hz and therefore the GPU utilization was well under 100%, which is an indication that Hashcat may not be able to run at such clocks.) But one thing we do know is, this is a pretty serious piece of hardware.


NVIDIA GeForce GTX 1070

1920 cores
1506 MHz base clock, 1683 MHz boost clock
8GB GDDR5
150W, 1x 8pin power
94C max temp

The GTX 1070 reference design (aka "Founders Edition") will be available on June 10 for $449. OEM designs are expected to start at $379. We don't really know much else at this time.

This post will be updated with more information, pictures, and benchmarks as they become available.

Told you

[epixoip]

Oh, bullshit you did!

Anyway I think you're crazy, 50% is way off base from what will happen in reality. I'm still expecting max 20% and that's being optimistic.

I'm not crazy at all, just going with the facts [...] We will see who got closer to reality, your optimistic 20% or my pessimistic 40%

Obviously *I* was closer, 15% is a lot closer to 20% than it is 40%

[Flomac]

You're kidding, right? According to Nvidia the GTX 1080 is 70% faster than the GTX980. You cannot steal out of this discussion by claiming the GTX1080 is 15% faster than a Titan X, since the GTX1080 is clearly not the successor of the Titan series (which is still to come). We always compared GP104 vs GM104 and GP100 vs GM100. And the chip performance raises by 70%. Far away from your estimated 15%.

I respect your knowledge but in this case you were miles away from being right.

According to my preliminary calculations, 1080 should do ~18129M p/s at stock clocks (no boost) for MD5, but since it's derived from old gen's data (Maxwell), the estimation should be skewed, either up or down.
Take the speed with a pinch of salt.

"The new cooler will only feature on "Founders Edition" cards bought directly from Nvidia.com. The GTX 1080 Founders Edition will retail for $699, with the GTX 1070 Founders Edition costing $449. Those after the lower priced cards will have to look to partners like MSI and ASUS, which will use their own cooler designs."

Let's hope that OEMs will offer something similar instead of the more popular axial fan coolers.

I jump in with this very technical comment: the twitch show was very ilarious. Especially when jensen & paul jokes each other 'bout the slideshow.

How many smm does the gtx 1080 should have?
10 series should draw almost 200W (a 6pin or a 8pin peg) less than the previous?

I respect your knowledge but in this case you were miles away from being right.

I was joking but I also wasn't "miles away from being right." Looks like you've got it all twisted.

Our previous conversation on these forums was about Tesla P100 vs Titan X (or a GTX card closely resembling P100.) Given the fact that there is zero overclocking headroom on the P100, I still maintain the P100 is at most 14-16% faster with hashcat. Our conversation was not about GTX 1080 vs GTX 980, or GTX 1080 vs Titan X. And indeed, the GTX 1080 does not even remotely resemble P100. It looks a hell of a lot better. 

On IRC I've stated numerous times that I expected the GTX 1070 to perform about like a GTX 980, maybe midway between a GTX 980 and 980Ti, and the GTX 1080 to perform about like a GTX 980Ti, maybe midway between 980Ti and Titan X. And I was correct:

GTX Titan X - 3072 * 1515 = 4654080 MIOPS
GTX 980Ti - 2816 * 1515 = 4266240 MIOPS
GTX 1080 - 2560 * 1733 = 4436480 MIOPS

That literally puts it smack-dab in the middle between the two, which meets my expectations.

The x-factor here, something I didn't predict, is that this card can apparently run at 2114 MHz, maybe even higher. That's absolutely insane, nobody predicted this. 1800 MHz maybe, but 2100+ MHz? No fucking way.

Now, we still have yet to verify that the non-founders edition can be overclocked that high, and we have yet to verify that the clock can actually be sustained that high when running hashcat. But assuming it can,

GTX 1080 - 2560 * 2114 = 5411840  MIOPS

Fuck me, that's fast. But even if we can't sustain 2114 MHz while running hashcat, we only need 1818 MHz to be as fast as the Titan X, which should certainly be no problem.

And this is the one thing I did get wrong: I said we likely wouldn't see a card faster than the Titan X until the "GTX 1080 Ti" (or whatever they will call it) is released 6 months later. Now mind you the GTX 1080 probably won't be much faster than Titan X, only just, but it looks like it will indeed be as fast and possibly up to 10-16% faster, depending on where we can pin the clocks. 

So no, I absolutely wasn't miles away from being right. I was actually pretty damn close to right. But nobody predicted 2100+ MHz clocks.

I just wanted to add an amendment.  According to the linked article, it looks like the lowest price might be around $600.  It will be interesting to see what happens to the pricing of the Titan X and its siblings when the GTX 1080 and 1070 hit the market.

Fun times ahead, gents.  I look forward to the initial benchmarks and other related findings.

Cheers.

Yes, the $600 MSRP for the GTX 1080 is covered in the first post. The GTX 900 series cards have already been marked down.
