GTX 1080 no compatible with OCTANE V3!??

[Lewis]

Thanks grain, that's really interesting to see result. So currently (without much optimizations) it's close to 980Ti with speed.
Hopefully OTOY can bring on full Cuda 8.0 support/optimizations soon.

So okay, the 1080 isn’t much more faster than the 980Ti, but much more expensive.

It's not faster at all currently BUT this is UNoptimized octane for Pascal GPUs, Maxwell GPUs weren't faster than Kepler when they first introduced until Otoy optimized Octane to work better on Maxwell (750Ti, 9xx series and TitanX series).

Okay. Here in Germany the GTX 1080 has a price tag of 729,– EUR. The 980TI has a price tag of 459,– EUR. So the 1080 is about 60 percent more expensive, but not 60 percent faster.
Perhaps the 1080 has a less power consumption. How many years do I need for an amortization of these extra costs?

Perhaps the GTX 1070 is an alternative to the GTX 980Ti, it has a tag of 479,– EUR and two 2 GB more memory.

That's one way to look at problem/comparison BUT:

1. What if your 980Ti don't have enough VRAM for your scene ?
2. What if optimized octane gets 1080 at 20% faster than 980Ti and you have room only for 4 GPUs in your case/MB so you can get so in total you'd have much more power of 4*1080 than 4*980Ti and at the end you can deliver your project faster or with better quality under same time (more samples) to your client(s) .

Then you will amortizate cost difference very quickly - right ?

Also price of 1080 will fall slightly as the marked demand stops being so high. Heck i see 100 EUR differences in some models on our local market and there is still 980Tis which cost 90% of price of cheapest 1080 depending on vendors, fans, PCB, clocks....

Hi Guys,

again, no science involved but;

Rendering a car to 500px in Octane Standalone, PMC, HDRi Background etc

GTX970 = 54sec
GTX1070 = 37 sec
2x GTX1070 = 19 Sec

Here in NZ we seem to pay a bit over the international rate for GPU's, but indicatively a GTX970 cost's me around NZ$550 and a GTX1070 is NZ$825. This is interesting, because the dollar to compute performance is very similar between the two cards, but generally with a new product you would expect to pay a premium. With the 1070 you're getting double the VRAM, so as it stands at the moment the GTX1070 appears to be the better value option.
Here in NZ GTX 980Ti's are around $NZ800, but I haven't got one to compare the performance to the GTX1070. Having said that, the GTX980Ti would have to be getting a tangible performance increase over the GTX1070 to consider buying one as the price is only a few dollars cheaper, you're buying old tech and getting 30% less VRAM.
I'm sure the GTX1080, GTX1080Ti and the new TITAN that follows are all faster than the GTX1070, but you'll be getting into some seriously diminishing returns on the performance versus cost front.

Cheers, Dan.

@Lewis: Yes, You’re right, there are more aspects.

For me, it is not appropriate to wait, because I need it today. I can not wait for optimizing. If the 1080 will be optimized someday, I can sell my 980Ti GPUs and buy 1080s. Or I can build a cheap computer for network rendering and put the old GPUs into this computer. This is better than wait.

Maybe Otoy have optimized it when the release of Titan P is ready

[wrapthereal66]

oh... ok so 3dsmax plugin is not invalible ... shit

[acc24ex]

...OK, so far it seems like the same issue when 6xx and 7xx came into play, they actually had worse speeds than 5xx cards ..

- and still 980ti is 20% faster than 590gtx ..

or 590gtx is about 20% slower than 1080 - wow, really, 5 years later?

How long till the new optimisations .. ?

But it's OK I guess, I predicted, that the 1080 is going to take at least 6 months to a year until it's even worth considering the upgrade ..

- well, at least I learnt something during the last 5 years of octane development - BTW I'm still rocking the 2.21 kernel on 3dsmax .. and by the loks of it it will be another year (or two) I don't mind that much that I paid the 50$ upgrade (that I will not use for the next 6 months to a year) but I'm pretty much productive with what we already have

- would be really really nice if I could actually really use my bought and upgraded licences (two actually, one personal, and one business).. but it's ok, I still have many years until I'll retire
