Geforce Titan / 780GTX

[niuq.cam]

Seems that many people expect these cards perhaps who will finally accelerate rendering.
I'm in the starting blocks, waiting for the first tests in New Zealand.

Interesting Octane benchmark results for the GTX 780 from Tom's Hardware:

Despite its provenance as a GK110-based card, the GeForce GTX 780 always comes in behind the older 580 when it comes to pure rendering. Octane is the sole exception.

I see that GTX 780 are on sale now in NZ for $1150 and Titans have been going for $1800.
Looks like the GTX770 will be the equivalent of the 580 for Octane with the bonus of the extra texture count.
So the rendering power of 2 xGTX780 = 3xGTX770 and we guess the 770 sells for the same as the 680 which is about $775 so no free lunch. If you are just after speed and not so interested in 6 gb vram these are a good buy IMO
Relatively quiet and draw less power. I presume the same water kits will fit the 780 as the Titan.
The question I have is, given this 7xx generation is a bit of a filler until Maxwell arrives and Nvidia raided the Tesla bin for the Titan and the 780, will Octane performance for the 880 be about the same as or less than the 780? I am thinking we may not see a decent performance increase again for 3 years ie the generation after Maxwell and perhaps never again have 6gb for a Geforce. What if Nvidia keep crippling their compute performance for Geforce, what if Maxwell architecture is not itself compute friendly, what if, what if....

Toms Hardware is using Octane for CUDA benchmarking: http://www.tomshardware.com/reviews/gef ... 16-26.html

gigabyte overclocked version is cool indeed http://www.guru3d.com/articles_pages/gi ... iew,1.html
looking at the test results for games it seems like 2x 780 are enough to give 50-60 fps at 2560x1440 in most cases.
Now I wonder if 3gb is enough for my Octane purposes ...4 would have been nice
hmmm choices...

have to say I've waited for this update for sipome time, but looking to what has come out..it leaves with a reinforsed thought that Titan is the best deal for now..new 780 isn't atractive..at all =) even less than 670 =)

Yeah I don't think the Titan is going to be replaced soon. I worry that Maxwell isn't going to be very impressive though. I can just see it being all textures and effects for gamers but not much chop for compute. 6gb is a bit unusual for a Geforce too. I think we might have been lucky to get a hand-me-down from Tesla like this. It is still pretty expensive though. I would love to get 2-3 of them but its kind of hard to justify that for the amount of use I would put them too. Different if I was doing rendering full time for a living.

The GTX780 is pretty near the same performance and its more reasonably priced but it just falls a bit short for serious Octane use with 3 gb IMO. Power consumption is a little disappointing too.

The GTX770 just seems to be a warmed over GTX680. Solid performance but not a move ahead. Still there ought to be a 4gb version which is a good compromise between work space and cost.

I'm not sure what to do really. Each has merits but don't quite satisfy what I was wanting. The Titan seems to be the best option if you can put it to a decent amount of use. Otherwise perhaps its better to wait for Maxwell and the hope a GTX880 with 4gb comes close to a Titan but is not pulled up in price by having a Tesla derived high end card above it. You would hope instead there will be a return to a dual gpu GTX890 with the die shrink and all.

The local release stock of 780 have sold out now anyway so I have some more time to think about it...I guess Titans are going to be around for a year or so if I change my mind, again.

Bought 4 GTX 680s here and the benchmark looks the same as Tomshardware.
I went for lower price and 3gb ram. It's around 40% cheaper than a Titan.
All good for now. Waiting for a card with 12 GB

Wait no more: http://www.fxguide.com/quicktakes/nvidi ... dro-k6000/

So on Nvidias Maxwell generation we will see 12GB on consumer cards for sure I guess.
This new Pro-Card will be made for double-precision again I guess.
