NVIDIA Pascal Thread

How can Nvidia advertise 2GHz overclocking on the 1080 in their video? That seems really irresponsible to advertise an overclock.

They are proud of their achievement man.

About the reduced IPC: No progress on IPC doesn't mean no design changes from Maxwell. It's entirely possible that they spent some of their IPC to make it clock faster. The speed demon/brainiac tradeoff is a real thing.

At least Nvidia actually got the increased clock speed, unlike AMD with Bulldozer and Intel with Netburst (neither of which were really that much higher clocking than contemporary high-IPC designs). This strategy is likely to work much better in the GPU arena than on CPUs, due to their greater simplicity and inherently parallel nature. But I have to wonder how it's going to fare in the mobile arena. Will it still clock significantly higher than Maxwell at the same power consumption? It's worth noting that the official TDP of GTX 1080 is 180W, up from 165W for GTX 980. On the desktop, that doesn't matter a damn (either way it's one 8-pin or two 6-pin connectors) but it could be a potential issue on mobile SKUs.

I know some people don't care, but this launch must be the worst mm^2/$ of any GPU in at least the past 10 years. Nvidia's gross margins are probably through the roof.

Cheapest retail 980ti's cost 680€ in my country, at what price should I be happy to sell mine for ? Gotta be fast while people are still unaware of the 10xx line

That was pie in AMD'S face.

Your next thread crap will earn you a vacation. I am serious. This is the Nvidia Pascal thread, not AMD.

Moved to Nvidia forum. Not sure why it wasn't there in the first place.

It's pretty much confirmed now that P10 will be far better on mobile. Whether it actually results in more mobile sales for AMD is another question :sneaky:

All I can say is the Pascal reveal makes me feels glad about not buying any post 2014 28nm GPU.

 

[xpea]

They won't do that, the bandwidth reduction for segmentation purposes already happened in moving from GDDR5x on 1080 to GDDR5 on 1070. Also notice the price increase on 1070 from 970, they don't have to cheap out as much as they did with the 970 which was introduced at a very competitive price point.

yeah but it's also 4GB vs 8GB

they must be confident each card can achieve that (they were running Paragon demo at 2.1GHz air cooled at 67C).
And JHH said many times that 1080 has big overclock potential

(hopefully it's not another overclockers dream fiasco :biggrin: )

 

[moonbogg]

What are you talking about, we wont' have another graphic card for another year, or am I missing something?

I thought it said available like soon or something. Didn't it? This new node does have me excited. My gawn imagine those big die chips with a huge OC? Oh lordy.

I think most of us expected that.

Where NV will cash in are all the VR early adopters who bought Maxwell thinking it's great for VR. Pascal not long brings higher performance, but it also lowers the motion latency to make your VR gaming experience more enjoyable. It's the comfort factor that's key. When reviewers test it, they will note how much more "comfortable" it feels and that will seal the deal for Pascal.

The other major cash in are all the Maxwell owners, as by this year's end, there's a lot of DX12 games and AAA titles are truly next-gen, lots of compute effects usage, will see Pascal separate from Maxwell (which tanks) with a big gap.

By getting your user base to upgrade often, it's a really good way to run a profitable business. Kudos to JHH, he's a great CEO.

And hopefully 1070 doesn't have the slowass RAM for the 0.25GB (or was that 0.5GB?) fiasco like the 970 did.

 

[Actaeon]

Sidegrade for 980 Ti owners but it will be a nice upgrade for everyone else that needs to upgrade.

$600 is a lot of money but not totally unexpected. Nvidia has been raising price of x04 chips for a while now. The $380 1070 will be a nice buy, though I expect peak performance to be limited by the GDDR5 on 256bit bus.

The clock speed increase is very exciting. This makes me really excited for Volta when they can combine those clock speeds with some actual IPC improvements.

Pascal will be out nearly two years after Maxwell v2. I expect that a new architecture on a new process will be much better.

You really sound bitter.

 

[Actaeon]

And hopefully 1070 doesn't have the slowass RAM for the 0.25GB fiasco like the 970 did.

Even if they did the same .5GB slow ram thing, it would probably a non issue with 7.5GB of VRAM. That is more than plenty @ 4k. I can't even saturate my 6GB of VRAM.

It was a problem with the 970 because 4GB was already cutting it pretty close, so 3.5GB really hurt.

 

[JDG1980]

GTX 1070 (6.5 TFlops according to the slide) has a little more raw shader power than Titan X (6.1 TFlops). It will be interesting to see how that converts into real-world performance. Memory bandwidth will definitely be lower, given the use of a 256-bit standard GDDR5X bus. And possibly ROPs? Titan X / GTX 980 Ti has 96 ROPs; Nvidia's official release says nothing about ROP counts, but TechPowerUp's database thinks GTX 1080 has 80 ROPs.

My guess is that GTX 1070 will provide the expected performance scaling on 1080p and probably 1440p, but it may fall behind at 4K. This would be considered acceptable since 4K is still a bleeding-edge resolution for gaming. GTX 1080 should do fine (memory bandwidth is a little lower than GM200 cards, but not much).

I doubt there are many additional improvements in memory compression - all the low hanging fruit was already squeezed out with Maxwell. After a certain point, the tradeoff in die space isn't going to be worth it.

Anyone have a breakdown of what was announced? I missed it because I was in the air.

Pretty impressed with the 1080. That should hold the crown for the rest of the year i'd imagine.

With the extra compute power and no penalty for context switches like Maxwell had I can see it increasing its lead over the 980ti in DX12 games that use async.

SOme people will call that Maxwell being crippled ,kinda like Kepler vs Maxwell.

For me? I find it a reason to upgrade.

The slightly weird thing is that the 1080 has 9 TFLOPS (almost 50% more than Titan X), but yet it is only 20-25% faster. So based on that you would expect a 6.5 TFLOPS 1070 (6.6% more than a Titan X) to actually be slower than a Titan X.

But then again they did say that the 1070 was faster than the Titan X, so who knows.

Thanks. So is the founders edition 100 more just because it's available earlier? Was hoping the 1080'd be no more than 500. Guess I'll be getting a 1070, which should still be a nice upgrade for VR from my 7850.
