** The Official Nvidia GeForce 'Pascal' Thread - for general gossip and discussions **

No wonder they only showed the front of the three new bridges at the event. They only support dual SLI, just at different card spacings.

Also it appears that the bandwidth per port is the same, they have just doubled the number of usable ports between cards to double the bandwith in dual SLI setups. So the bandwidth per port appears to not have changed.

That makes me sad :(

I don't think we should have to SLI thousands of pounds worth of hardware just to run a game at max graphics.

Why not? How else do you expect it to work? It's not the GPU manufacturers fault that developers make demanding graphics that take incredible amounts of power to run at super high resolution like 2160p.

You can always stick to older games if all you're interested in is whether you can 'max' something or not. Dishonored plays at 4k/60fps with just a GTX970.

IMO, 2 or 3 years away yet from getting a single card that allows you to turn all the eye candy dials right up to 11 and hit a solid 60fps @ 4k....we is a long way off from that yet.

If they released a card capable of that now, then people wouldnt need to buy their next planned Ti version :p
 
Yup, drivers have been flawless for me on a single 290, even before crimson, going all the way back to my 4850.

I did have serious issues when I first got my 290 although I think that was down to my windows install or something else as *touch wood*, not had those BSOD issues for a long time.

Only one issue that I've had that was down to AMD and that was in battlefront when first released, shadows/lighting/texture system was broke and made any ice maps unplayable, took them a couple of weeks to fix iirc.

A strong argument for reference, in addition to the exhaust at the rear, has ALWAYS been the cheaper price... no longer.

The reference cooler hasn't been the cheapest for a good few generations now, probably since NVidia first showed off the silver blower type shroud.

Indeed. In fact if you wanted the titan cooler on the 970 or 980 it was a hefty premium. The 970 with the tian cooler on OCUK is still £350!

So do you disable motion blur, chromatic aberration, lens flare's, depth of field etc? since to me they lower the IQ of a game and waste FPS.

I disable motion blur yes, lens flare, sometimes, depends on the game. I disable depth of field usually too. Try to get it as real as possible. GTAV has very nice depth of field. especially when using weapons, quite realistic.
 
If the 1080 can see me through 3440x1440 for the next year or so I'd be happy. A single TX almost does it with a good overclock so I'm fairly hopeful.

New sub to that channel - that guys brilliant and actually uses facts and reason.

I didn't know that existed on the the internets.

Seems like early Founders Edition 1080 is to be avoided if you can wait. I'll probably goto third party 1070 just to run my X34 better, then onto an HBM2 equipped 1080 (whatever it's called) in 2017/18 to push the new Vive 2.0...

Cheers

Why avoided? I thought the founders were reference and the others arent? Therefore if you plan to watercool then you need the founders edition?

Or have I got that wrong?

Yup, it'll only be the odd mega-demanding game that'll tax it badly i.e. The Division.

Tbh I have Division running at Medium settings @ 4k and I'm quite happy with it! Between 50-60fps, still looks great and Gsync is making it feel like a constant 60 :cool:

Well I recall the 980 OCUK Reference being the cheapest 980 at one point (£400 as I remember), until the exchange rate went south.

Interesting article:
In our initial talks with Nvidia and their partners, we learned that the GeForce GTX 1080 is coming to market in several shapes:

GeForce GTX 1080 8GB
GeForce GTX 1080 Founders Edition
GeForce GTX 1080 Air Overclocked Edition
GeForce GTX 1080 Liquid Cooled Edition

Stock GTX 1080 is clocked at 1.66 GHz, with Turbo Boost lifting it to 1.73 GHz. Founders Edition includes overclocking-friendly BIOS to raise the clocks to at least 2 GHz, and the presentation showed the chip running at 2.1 GHz.

...
partners such as ASUS, Colorful, EVGA, Galax, GigaByte, MSI are preparing custom boards with 2-3 8-pin connectors. According to our sources, reaching 2.5 GHz using a liquid cooling setup such as Corsair H115i or EK Waterblocks should not be too much of a hassle.

And As I have been saying all along, Pascal architecture was redesigned to allow higher clock speeds and more efficiency:
n the search for absolute performance per transistor, Nvidia revised the way how their Streaming Multiprocessor works. When we compare GM200 versus GP100 in clock-per-clock, Pascal (slightly) lags behind Maxwell. This change to a more granulated architecture was done in order to deliver higher clocks and more performance. Splitting the single Maxwell SM into two, doubling the amount of shared memory, warps and registers enabled the FP32 and FP64 cores to operate with yet unseen efficiency
Click to expand...

Given the choice of twice the number of cores running at half ht clock speed, or half the number of cores at twice the clock speed, the later will always have higher performance even if the theoretical performance is similar because it is very hard to make use of increasing parallelism. Which is why Nvidia has continuously redesigned CUDA cores to be more powerful and efficient, why even Maxwell clocks quite high compared to Fiji, and why all the thousands of CU in Fiji just aren't utilized optimally.


Similarly the article goes on to say that NVidia are diverging their product lines, so GP100 is FP64 compute focused, GP104 is gaming focused so both parts are much more efficient than previous generations. Something I mentioned At the Gp100 launch when certain brand-affiliated forum members were proclaiming the death of Nvidia and the dominance of AMD based on ridiculous generalizations from GP100.


The article does say that Pascal doesn't do Async compute, which puts into douybt a lot of the rest of the articles accuracy because Pascal like Maxwell certainly does support DX12 Multi-engines and we know form the GP100 announcement Nvidia has made a lot of changes to reduced the cost of context switches which will massively increase performance. In theory if context switch costs can be reduced significantly then it is a much faster approach than used in GCN, especially with god develop support.

Really is coming across as if you have a 980 then it's a decent upgrade. Ti? Not so much....

Benchies will tell us more!

That was always going to be the case going forma high-end previous generation to mid-end chip of the next gets you something like 30% performance gain and lower power/cooler/quieter. 30% is not a big deal in many situations, if you already get 90FPs then who cares, if you are at 35FPs on 4K ultra then 30% wont be enough. But if your favorite game is at 50FPs then a 30% boost would be very welcome.

Then there is the fact that Pascal will only get faster with newer DX12 game engines increasing the lead. It also sounds like the 1080 will overclock extremely well.



However if I had a 980ti I would probably be waiting for the 1080t as I don;t see the need to continuous jump cards.

What are they doing? are they gimping overclockabilty on none Founders Edition cards?

Like none K series CPU's?
