Geforce RTX

Mon Aug 20, 2018 8:00 pm

So the new rtx geforces have just been revealed - to be on sale one month from now.

I intend to sell my 2 1080s and replace them with at least one 2080ti.

My question for devs is:

We have heard last week that quadros are 5-8x faster in octane than pascal cards and their expected octanebench score will be about 700-800. Will the same be true for geforces, since they seem to be just slightly cut quadro chips ? Or No clue.

The other thing, when can we expect octane version which will support turing architecture? Even if the rtx tech is not working right away, i would need at least basic funcionality - that is if i buy one and sell my pascal cards....

Thanks for response

I would love an answer to this as well, I am trying to plan for my next hardware upgrade.

Multiple 1080s - 1080tis or a rtx 2070, 2080 or 2080ti? I guess there'll be benchmarks after they come out, but I want to plan ahead and try to get one before they run out again.

Yes, it would be nice if otoy could provide early benchmark results so we could know if we should start selling and pre ordering the rtx cards...

CEO of Otoy said rtx quadro to be 8x faster...and it's a game changer...

Will one RTX 2080 TI be 8 x gtx 1080 TI speed?

I've also been waiting for the new cards to come out to buy a new computer. My main focus is on Octane Rendering (in C4D) and I'd also love to get an official go ahead on the new 2080ti from a developer, thanks!

Maybe with new (and unfinished) vulkan kernel.

But until then, Cuda performance on Turing is as good or better then any Volta (at least on quadro rtx).

Now will octane use both rt cores (10 gigarays in 2080ti) and cudas? Or there won’t be cudas anymore ?

+1 Would love to get more information about how these new cards will perform.

I got caught in the frenzy last night and ordered a 2080ti, so I guess I'll find out soon enough. That vulcan test is amazing but not sure how much practical knowledge I can take away from that.

As far as I can tell the new cards have nearly double (2/3rds?) the number of Cuda cores, so there will be at least a 150-200% speedup over a 1080ti. Not sure if Octane uses any of the new RTX cores. And tensor cores, what are they? Do they get used?

Thanks for the response. Does the mention of CUDA performance being at least as good as Volta mean if i buy the card next month, it will work with Octane right away and i wont need to wait further 3 months for some Turing enabling release?

And when do you reckon that Vulkan kernel will be ready for release? Wild guess at least... TBH regular Volta performance is not really enough to make me splash so much money on these Turing cards....its the fabled 5x-8x speed-up which makes me consider their purchase.

Hi,

An interview with Jules Urbach. Go to the 1 min 20 sec mark to hear about the new RTX tech.

From whatever I have understood from the interview, we won’t see any kind of major speed improvements based on RTX till next year. The core technology that will utilise it is still being built. That will be octane 2019. Also he mentions that there are some issues that NVIDIA has to solve. So don’t buy an RTX card expecting some kind of 5-8x improvement.

Even though the 2080ti has almost 900 cuda cores more than the 1080ti and that should definitely make some improvement in speed, but the fabled 5x - 10x won’t happen any time soon. At least that’s what I think.

Right now I'm a more excited to get attributes in the Octane 2018.1 than anything else.

Indeed. Gamers are also disapointed as the RTX seems for them more of a gimmick...2x gtx 1080TI will still be faster then 1gtx 2080ti for the same price...on their current games...one can always disable the rtx and play...this will also keep up the prices of gtx 1080ti...

Kinda scammy marketing...i almost sold my ti's lol
