Thanks Greg

I agree with Greg - no experience with that specific board, but I've had real issues in the past with Gigabtye mobos and newer graphics cards acting up. It's the main reason I went for an Asus last time round.

he doesnt even know!! hes just guessing!!
pffff

lol Maybe but i checked and the latest is F7 so may as well update it anyhow.

since I've sold my 980 Ti I had no pc to use at all, so just grabbed a 660 for £30 off gumtree!! got it to 1250mhz though doesn't handle 4k very well however if the hybrid 1080s from Evga get announced at computex with an ETA I might just hold off getting the FE 1080 as 2.5ghz.... seriously with 2.1ghz we're 50% faster than stock 980 Ti with 2.5ghz we're 75% ahead of a 980 Ti.... I think this 1080 is going to suprise a lot of people (for the better

It 'felt bad' because it's not powerful enough to run modern games at 1440p/60fps. Not because its memory bandwidth was some major bottleneck.

A 980Ti *is* capable of running these games at 1440p/60fps, though, which is why it felt much better. A solid 60fps will always be a significant improvement over a rocky 30-50fps framerate.

This is just a raw horsepower thing, not a memory bandwidth issue.

Yes and a large part of that was the memory bandwidth and 256bit vs 384bit on the 980ti, 980 had more cores but same memory and was still not great at 1440p or higher, both were 1080p cards with 256bit memory bus.

If memory bandwidth makes no difference at higher resolutions, why GDDR5x and HBM? Totally pointless then?

I would actually test the card. Its working then leave the Bios. If its not broken dont try fix it is always my advice with Bios updates etc.

I updated the bios on an old 3960X setup (so it could run Maxwell) that could OC to 4.9ghz, with the latest bios it will only do 4.4ghz.

I am going to have to find an old bios to get it working properly again.

2.4Ghz factory OC from Gigabyte.

Looks like the rumours of hitting 2.5GHZ with sufficient cooling and power are true. It will absolutely fly at those speeds.

For gaming, that would put it about ~60%+ faster than a 980Ti at a guess. 1080 is looking very impressive on paper and can't wait to see reviews.

I've more or less committed to waiting on the HBM2 version of Pascal or Polaris later in the year as even ~60% faster than 980Ti would leave me sub 50 FPS in most games at 4K DX12.

 

[BriT]

Hmm ok, i'll leave it for now and test the card as said. Thanks.

I don't think 75% is viable to be honest and it looks like you are assuming a linear performance increase in line with overclocking. If stock for stock the 1080 (1744+boost) is 25% faster than 980Ti then a ~700-750MHz OC would be ~45%. That would generally give 30-35% boost in performance. 60% IMHO faster stock 980Ti vs 1080 Max OC, or if we go max OC vs max OC then ~35% faster overall. Though that's hardly poor is it

I'm definitely looking forward to actual (unbiased) reviews though. IMHO it has been far too long since we have been stuck with 28nm.

I can't see it. Even Nvidias own slides had it sitting at around 25% faster in general gaming performance and we have apparently seen the 3d mark scores.

Is the 1080 likely to be a 'cut down' card? I see a lot of people talking about the 980 being a cut down version of the 980Ti, and within less than a month of the Ti being out it was already the same price as the 980 on release.

Is that what we'll be seeing now? If so what is the point in getting a 1080 if it'll be shafted by a much better performing and only slightly higher priced 1080Ti?

 

[Seanspeed]

Yes and a large part of that was the memory bandwidth and 256bit vs 384bit on the 980ti, 980 had more cores but same memory and was still not great at 1440p or higher, both were 1080p cards with 256bit memory bus.

A 980 was not good enough for 1440p/60fps, no. Not because of bandwidth, but again, because of horsepower. A 980Ti is only *just* good enough for 1440p/60fps and that still involves lowering settings in plenty of games. So of course anything less wont be.

And I didn't say anything about better memory bandwidth not being good for higher resolutions. But I think it's important to note that these bandwidth bottlenecks only *really* start to pop up when you get into really high resolutions like 4k. I think it's very easy to forget that 1440p is only 1.7x as many pixels as 1080p, while 2160p is a full 4.0x!!!! 4k has become such a household name around here, but I dont think people are quite appreciating the sort of leap it is. 1440p->2160p is a greater leap in resolution than we've ever, ever seen by far. And from 1080p, it's the freakin Grand Canyon.

What holds GP204 back at 1440p is definitely not memory bandwidth. I'm not saying it plays no part at all, but it's not going to be a notable bottleneck.

The 1080 is a replacement for the regular 980 yes. There will then be a 1080ti, which is the replacement for the 980ti. My guess is in October right before or after AMD's Vega gpu is released.

 

[JediFragger]

Ok, if the mega-overclocks are true then I'm def more impressed by the 1080

This is wrong for a start and seems to be common misconception on here. The 980 started at £400 on release ( not here but plenty of places you could get one for £400 or a shade over). Even the cheapest here was only £420. The 980 Ti was a £500+ card on release and apart from a few sales, is still a £500+ card (well, for a few more weeks anyway...)

^^ Imagine moving the slider 1Ghz to the right without volts that would be nuts.

Is it not a possibility that they'll skip the 1080Ti and go straight to releasing a Titan replacement? There's no guarantee of a Ti card

The 980 was not a 'cut down' 980Ti.

I realize there might be some confusion because that was the way it was with the '2nd gen' Kepler(780 was a cut down 780Ti), but that was certainly not the case with Maxwell. The 980 was its own thing, the 'full fat' GP204 card. The 970 was the cut down 980, much like the 670 was a cut down 680.

And the 980Ti was actually a cut down Titan X, whereas with 2nd gen Kepler, a 780Ti was actually an 'unlocked' Titan, but with half the vRAM. A bit confusing for sure, but something I'd expect any regular enthusiast to understand.

In the current situation, the 1080 seems to be the 'full fat' GP104, much like the 680 and 980 before it. If there is a 1080Ti, it will almost assuredly be a GP100 variant of some sort.

Nobody knows the timeframe for later cards. If nVidia created a 1090, which could easily be done, that would probably delay them in releasing any future Ti/TX cards and a 1090 would be more useful to the average user than a TX.
