My recommendation still holds that if you can sell your 980ti for over 450 do it. Trade up to the 1070 after market cards.

And fyi, not everyone gets 1500 ocs on 980tis....

The 1070 is a better newer 980ti just like Nvidia wanted.

 

[Gikaseixas]

I'll hang on to my 980ti until the next big die monster from either Nvidia or AMD. The 1080 is tempting but the 1070 is not worth the hassle of selling - buying - getting 5% higher fps

But you only need a 980ti at 1300MHz to equal an overclocked 1070.. and those card can be bought as is.
Which means that some 980ti models one can buy now are faster than the oced 1070 we see now.

1070 is not better than the 980ti.. it might be priced lower which would make it more attractive than a 980ti, but other then that the 980ti is simply the better choice over the 1070.

How does the nano compete with the 1070?
Less VRAM, More power consumption, etc.

Just like AMD using the R9 290 to combat the 970 didn't work, you can't use the nano to combat the 1070.

People want something NEW. Not to buy an old product. 1070 will firesale well just like the 1080. Especially when the competition has no product out for awhile.

Remember the drivers... AMD cards tends to last longer than nVIDIA ones. Useful for people who don't tend to renew their cards every year. Not so much people at least in LATAM wins over 3000 dollars each month to change constantly the cards.

On the other hand... why 1070 when the 1080 is so much better and cost only 30% more?

379$ - 599$ means that 1080 is 60% more expensive for about 25%performace boost (need to be confirmed with more reviews). For many people 220$ means big difference.

However if the performance boost gets over 50% thanks to OC... the scenario totally changes

At this point - based on the benchmarks we've seen so far - it seems wiser to buy a new 1070 at $380 than a used 980ti for the same price. Although you get a bit more performance from the 980ti when overclocked, everything else favors the 1070 - newer architecture, lower power, better driver support.

looking at this, than I compare it to 460 1gb and the 8800 gt reviews/charts. I feel like pc gaming is no longer better than consoles.

even with a node shrink we get 20% performance improvement and a price increase of 100$ or more in similar performance/price brackets. I feel like 16nm/14nm is gonna be at least 2 more generations just like 28nm. this incremental performance spread over the years is almost 100% proof.

this was suppose to be the long awaited node shrink after 3 years, and we got 20% performance. that just plain sucks.

Agreed. Make it worse?
PC Gaming starts to have the same syndrome as Console one... lots of sequels, who are mere rebrands and literally few new content. Some exceptions like the Witcher 3 or Fallout are still alive, however the rest are suffering the syndrome

 

[Udgnim]

it's not about total performance or best possible performance

it's about best performance for a price segment someone is willing to spend money on

 

[Grooveriding]

Switching from a 980ti that overclocks well to a 1070 is going to give you a performance downgrade. Long term you will get more performance out of that 1070 though. Once driver neglect hits Maxwell the 1070 is going to be faster than a 980ti, noticeably faster in certain cases I'd expect as well. Just look at how the 970 compared to the 780ti after six months of Kepler driver neglect and new games releasing.

All that said I wouldn't switch from a 980ti to a 1070, but if I were buying in that price bracket today I would take the 1070 over a used 980ti. If you have a 980ti, the only option that will do anything for you right now is the 1080. Even then if you are running one of the 1.4-1.5ghz 980tis you should only expect about 20% more performance when you overclock the 1080 and you have to overclock the 1080 for it to be worth the switch imo.

 

[Head1985]

Problem is pacal is not new architecture.It is maxwell on 16nm with better delta color compresion.
Kepler to maxwell is different story.
192SP/SMX to 128SP/SMX.
I dont think pascal will get any better with new games or drivers(over maxwell)

I see only chance pascal will be better than maxwell over time is if pascall have full asynch compute working.So it will be alot better under dx12.But if is asynch compute same gimped on pascal it will be same even under dx12.

not when I can find a used 980 ti for less than 300$ one of the good AIB too, not the dinky reference models. I have already started hunting, got a few targets. a used 980 ti + 20% oc would be a good upgrade for my 290. especially when it is less than 300$ and even less once I sell the 290

That's simply not true.

That's simply not true.

Then show me those changes..Except delta color compresion and that VR thing.

witcher 3 was really good. fallout was like vomit.

Your claim is based entirely on the shader distribution, and that's silly. You may have missed as well that GP100 and GP104 dont even use the same distribution.

Nvidia got whitepapers about the Pascal architecture you can dig into.

Or you can look to Wikipedia (although accuracy may be an issue - like the HBM2 stuff):

Architectural improvements include the following:

• In Pascal, an SM (streaming multiprocessor) consists of 64 CUDA cores. Maxwell packed 128, Kepler 192, Fermi 32 and Tesla only 8 CUDA cores into an SM; the GP100 SM is partitioned into two processing blocks, each having 32 single-precision CUDA Cores, an instruction buffer, a warp scheduler, 2 texture mapping units and 2 dispatch units.
• GDDR5X – New memory standard supporting 10Gbit/s data rates, updated memory controller.
• High Bandwidth Memory 2 – some cards feature 16 GiB HBM2 in four stacks with a total of 4096bit bus with a memory bandwidth of 720 GB/s
• Unified memory – A memory architecture, where the CPU and GPU can access both main system memory and memory on the graphics card with the help of a technology called "Page Migration Engine".
• NVLink – A high-bandwidth bus between the CPU and GPU, and between multiple GPUs. Allows much higher transfer speeds than those achievable by using PCI Express; estimated to provide between 80 and 200 GB/s.
• 16-bit (FP16) floating-point operations (colloquially "half precision") can be executed at twice the rate of 32-bit floating-point operations ("single precision") and 64-bit floating-point operations (colloquially "double precision") executed at half the rate of 32-bit floating point operations.

Edit: I guess this is GP100, not GP104.

https://en.wikipedia.org/wiki/Pascal_(microarchitecture)

Edit: Also preemption/fine grained context switching is a big deal, according to Mahigan.

As for Maxwell vs Pascal. The context switch involved between Graphics and Compute tasks caused a performance loss with Async compute + graphics turned on. Maxwell would process the compute task and then the graphics task with the fence enforcing synchronization between the two. This caused a performance loss.

With Pascal, that issue is fixed. So now Pascal only loses 0.1 FPS when Async compute + graphics is turned on. Pascal doesn't gain anything, because it doesn't support the feature, but it doesn't really lose anything either.

Some architectures, like Maxwell, suffer from slow context switching. What that means is this:

Graphics task is executing and you move your head. The application waits on the graphics task to finish execution (thread block), the SM then has to be flushed and then the compute task is pushed through. So you end up with a longer execution time (frame latency) which affects your FPS because you have to wait for the draw call to complete before you can preempt it with a compute task.

So switching between compute and graphics tasks, even if they're executed one after the other, incurs latency if your architecture suffers from slow context switching.

Pascal rectifies this.

Wiki is for GP100 not GP104.
just read this
http://www.anandtech.com/show/10326/the-nvidia-geforce-gtx-1080-preview
Pascal GP 104 is maxwell on 16nm with better delta color compression and with that VR thing.

EDIT:about asynch compute ..yeah i already said If pascal have better asynch compute it will be better under dx12.You guys should learn read.Under dx11 it will be like maxwell.We still dont know how asynch compute work on pascal.

That's not what the preview says.

As for features included, we’ll touch upon that in a lot more detail in the full review. But while Pascal is not a massive overhaul of NVIDIA’s architecture, it’s not without its own feature additions. Pascal gains the ability to pre-empt graphics operations at the pixel (thread) level and compute operations at the instruction level, allowing for much faster context switching. And on the graphics side of matters, the architecture introduces a new geometry projection ability – Simultaneous Multi-Projection – and as a more minor update, gets bumped up to Conservative Rasterization Tier 2.

And that's just some of the features. Not even going deeper into the actual uarch changes.

I was pretty set on getting a 1070, and while I know its still early, I notice most of the disappointment I'm seeing comes from comparing it to an existing high end card, 980ti titan x, fury etc. I get it 100%...

My question, for someone like me who is coming from practically nothing (amd hd5770), is 1070 still a good card to get for me? Or should I look at something else? My usage is video and photo editing. Light gaming...dota 2/h1z1

I have a 1600p monitor and would like to run things at native res or at least 1200p.

The 1070 is a super card for anyone with a 970 or below. Unless you play more demanding games than Dota 2. You may want a 1060 instead when they soon come.

 

[iiiankiii]

The GTX 1070 is a fine card. But, I think we've been spoiled by the awesome high scaling and overclocking from Maxwell. Nvidia basically pushed the GP104 cards to their limits. That's fine. It just removes the excitement of getting a lot more "free" performance from these cards.
