A 1450 mhz 980 ti nearly keeps up with a 1080 at 2100.  A 980 ti at 2100 on Ln2 would absolutely destroy a 1080.

Go find an overclocked result of a 1080 at ~2100 on firestrike, compare the graphics score to the one in my signature of my 980 ti at 1800 mhz, it's a big difference.

980ti has more streaming cores

Some dude spreaded rumors a while ago, with watercooling, the 1080 can hit 2500MHz.

 

What the...

This is why rumors shouldn't be paid attention to, but everyone kreygasm's over everything

Inb4 Pascal is the new Pentium 4.

 

Seriously though I don't understand why Nvidia would go for Clockspeed rather than IPC for any other reason than marketing.

From what I've seen, almost every single review has used a titan x or 980 ti reference model to compare to the new cards, despite the reference models clocking to only like 1100 mhz..  Even though most aftermarket cards get close to 1400 out of the box, and 1500 with some tweaking, something we won't see from the 1080/1070 cards from the looks of it.

What kind of clocks do you need on 1080 to beat a 1500 MHz 980 Ti? I ask because my brother wants to buy two Hybrid 1080s for 4k gaming, I wonder if I should tell him to snag two highend 980 Ti instead and save a couple hundred dollars.

look at firestrike results

I think you'd need ~2000-2100 of constant boost to beat it by about 5-10%.

 

But considering 980 ti can be had for so cheap, it's probably worth it to do that.  If you can find 2 really nice 980 ti that do 1500-1550 game stable 24/7, then you're honestly set. (you should be able to find this for ~400-450$)

I wonder if I'd be better off recommending my brother get two of these MSI GTX 980 Ti Golden Edition cards for $530 each after rebate.

Does preemption in the 1080 matter that much in DX12 to where the 1080 is still advisable if you don't care about power consumption? Pascal seems to have the same async compute deficiencies as Maxwell. I suppose Nvidia will start optimizing for Pascal soon enough though, effectively nerfing Maxwell.

He's not going to buy used. How are the MSI Golden Edition? With an all copper heatsink you'd think they're pretty premium cards. Are they known to hit 1500 MHz pretty easily? Because newegg has them for $530 after rebate.

He was comparing it to small maxwell, you know, 980.

They don't seem special to me, they've been bottom tier priced their entire retail life as far as I can tell.  Usually stuff like that is super cheap for a reason if you know what I mean.

 

Ask him if he's open to used if it has warranty, I've seen a few people selling cards that still have like 800 days of warranty for ~400-450

after a quick look on 3dmark it seems like an excess of 2000MHz is needed for 1080 SLI to match a 980ti SLI setup

at 2100MHz the 1080 SLI setup overtakes by a couple of hundred points in graphics score, at 2000MHz it's not quite there yet

God damn it. Once this hits common knowledge the cost of 980tis will bounce back up. No one in my area has tried to sells theirs cheap for me to take advantage of it.

I'm kind of blown away by the lack of 1080 postings on the benchmark threads here and over on overclock.net

 

I wish I would have been able to grab two on launch day because I'd be posting shit all over the place (good or bad)!

 

If any 1080 owners are reading this, stop being little school girls and put that card to work!

I think a lot of results aren't being posted on hwbot because of the 1.25v crap

Absolutely agree, but we have plenty of benching threads for others to share data in.

 

All the cards at both of my local Micro Centers were sold to guys who bought them just to resell at higher prices otherwise I'd be sharing some perf info with you guys.

[Coaxialgamer]

this is just my idea ( i am in no way an overclocking or electronics expert ):

 

Would it be possible there is some sort of physical component  in the power delivery system that would limit the actual voltage going to the gpu to 1.25V ? That should cause the voltage to stay capped at 1.25V , despite what the set voltage is in bios/software , and would cause a driver crash due to voltage being too low ( instability )? I know you can do something similar with AC , but what about DC ?

[SteveGrabowski0]

Gamers Nexus hit 2100 MHz stable with their frankenstein Hybrid 1080 and seemed to be limited to 1.06V (they said the max they could get it to was 1.08V for a few seconds).

 

http://www.gamersnexus.net/guides/2444-what-we-learned-from-the-gtx-1080-hybrid-experiment-oc-limits

 

That's disappointing to hear 2.3 GHz as a max OC on freaking liquid nitrogen and that you'd need that much more voltage to get those couple hundred extra MHz. I think I probably will recommend he stays with his 1080 Hybrid idea then since 2100 MHz seems doable without hitting that limit, and because he wants to buy one card at a time and if he waits a couple of months that second 980 Ti is going to be expensive as hell, probably defeating the money he saved buying the first 980 Ti instead of 1080 Hybrid. That just blows that watercooling isn't going to be able to get these cards much over air. Maybe I'll tell him he'd be best off buying Hybrid for the top GPU and saving $100 and going with an FTW for the bottom one.

No it doesn't seem possible, because even when people added external VRM boards and chopped off all the VRM, it was still doing it.

Ouch, what a dog of a chip for overclockers.

very strange ... Maybe an on-chip (or on-die) component ?

The thing that is reassuring is, atleast the guys working on trying to figure it out are insanely smart. If anyone can figure out a fix, it'll be these guys.

Talking about 2500MHz on core under water cooling ... probbably not possible,

But even if it would be, GPU is scaling very bad after 1900 or 2000 MHz on core.

Meaning that difference between 2000MHz clock and 2300MHz would be only like 1-3%.

so it seems like the 1080 is going to be a great chip for "normal" user , but won't be the best for water , ln2 etc overclockers ...

Wouldn't be possible with this volt issue.

 

If people are Ln2'ing cards and only hitting 2300-2400 on lots of cards tested, than water won't get anywhere near those clocks without a fix for this volt issue.
