OCTANE BENCHMARK: Submit performance scores for your rig!

So I read the thread and still not seeing a consensus. Is a titan worth getting at this point?

Nope - considering the fact 590 gtx and Titan gtx both reach almost identical speeds - unless you really need 6gb GPU ram
- what the hell is actually going on since nvidia rated Titan @2688 CUDA cores and gtx 590 at 1024 (in reality it works like a double 480 which has 480 cores)

- anyway - counting CUDA cores seems to be almost useless - I almost pissed in my pants when trying to check specs and I receive this page filled with animated transitions and explaining to me how fast this thing is: http://www.nvidia.com/titan-graphics-card - considering the fact my two years old 590 runs at the same speed in octane - this was incredibly annoying

- this thing is supposed to run at least 2.5 times faster than 590 considering the specs - can someone actually explain what is going on here - and what GPU architecture is going to run as it is supposed to - what's up with nvidia - they give us CUDA and then dumb it down as soon as software using it becomes popular? Are there same limitations in other GPGPU softwares?

TITAN vs GTX 590:
6GB - 1.5GB vram
224 textures - 64 textures
160W - 300W ? (power consumption during rendering, for 2xgtx680 (I sold them) it was about 320W)
good - poor overclocking abilities (I'll send some tests within 2-3 weeks once I get my new EK waterblock for TITAN)
80C-90C ? (automatic core speed adjustment for current temp. in titan)
(almost) silent - ??? (noise during rendering)
1000$-500$ (ebay for gtx 590)

Hi,
It's air cooling
1.2V
+450 is for mem. I can get it up to 500 when use the titan alone (in the box). Now I have also my 2 old 580GTX inside, so it's a little hot !
temperature is about 70°C
It's stable for all my render (ex bench finished OK with PMC).

On air cooling? 1.2V +280 core and +450 mem. and 70C???
Run MSI afterburner and watch core and mem. clocks and voltage during rendering. I bet your titan slows down to operate around 70C. I have no OC now and it's constant at 80C.

plus 1 gpu / 2 gpu
for me the power consumption is the more important aspect, if we do a comparison in power per watt there is no game
Titan rocks

the question is wheather You need? If YES, You're working on big scenes..
& have enough cash, there's nothing better on the market at the moment =)

@smicha
Soory I have not mentioned that the PC is NOT in my room, it's is remotly controled and it is in the garage where the temperature is about 18°C

Now I get it. What a mess

I agree to a degree, but there is another consideration now that the price of 590 cards is coming down and some here in the forum may be looking to pick up several cards to improve OctaneRender times. This comment is referring especially for those interested in running quad setups. Heat should be, if not the first, at least a major consideration in your choice of deciding 590 or 690, and speaking from experience unless you are willing to consider exotic cooling methods (which I am not) the 590 is not the way, IMHO.

I was a real opposer of laying out nearly $4K for 4 GTX690's as opposed to the 4 GTX 590's for less than half the price and I was able to get nearly the same performance in Octane Benchmark but after installing 4 590's this really was not practical for rendering. I have now put the 590s (I owned 7 at one point!) up for sale and am going over to 690's.

After spending several months building a custom rig just for Octane (specs in my signature) I could see the temps in the 4 EVGA GTX590 Classified were much higher than my previous 4 EVGA GTX580 Classified setup. My temps rapidly were hitting 97 to 100C + in just a few minutes of rendering. However after running a series of tests using the profiles in Afterburner and TThrottle I thought I could control the heat. My Cooler Master Storm Trooper Case has excellent airflow but cannot keep up with the heat generated by the 590s.

Case in point after finally assembling this rendering beast I decided to get down to business and start rendering some stills for our company using just 3 of the 4 590s. Unfortunately I was using our Octane rig in the office from a remote computer at my home. When I noticed the temps rising close to 100C I attempted to shut down the render but lost remote connection and was not able to log back in. By the time I got down to the office to shut it down, the computer was off and this brief render apparently blew our 3 month old Seasonic X-1250 1250W 80Plus Gold power supply. This was all in less than 5 minutes. I have seen total system power consumption of 546 Watts with just 1 590 let alone 3 like we were using so yes probably could have used a 2000W power supply but thought the Seasonic could handle it.

Some load comparisons between the 590 and 690 here http://www.anandtech.com/show/5805/nvid ... ra-fast/16

The power consumption together with the heat generated (100C + even with TThrottle engaged) make the 590 quad setup a volatile combination. The lower wattage and heat in the 690GTX has dragged us kicking and screaming over to the dark side of laying out beaucoup bucks to make Octanerender work the way we want it to. But this is just our experience, your mileage may vary.

of course - the heat being another issue - but I think we are talking about performance (speed) here - performance wise - no speed gain compared to a cheaper 590 - but a gain in more RAM, less power consumption, less heat..

- anyway I also have a 480GTX, two 580s, and a 590 - this was all in one machine - the 480 was flaming hot - so I am aware of the issue - yup it's a real pain in the ass
- without any additional cooling it reaches over 100C with no problem - resulting with a PC shutdown (you should really be extra careful running a bunch of GPUs on a remote machine like this - I think it should be obvious) - there is (almost) no way you could run 4x590 gtx packed tightly in a closed PC case without extreme cooling - I couldn't even run a single 480 without a fan right on top of it in a closed pc case

- solution my "office machine" > a 40x40x40cm wooden box (osb board) with a huge fan - easy to access everything - a detachable plexy board attached via magnets on one side attached to some screws which also keep a 1cm gap (and the fan already had those gamer lights we all adore) - easy access all around and nice and cool - other parts are from an aluminium pc case, and I am definetely keeping that kind of setup for future builds, running below 90C - but the beast becomes loud once you start rendering - everyone in the office notices

- so this was my solution - and an idea for simpler cost effective cooling solution (actually it wasn't the cost - I actually wanted an easy to access PC case and a custom PC box - and there is nothing I found that I liked)



- cheaper than getting a Titan
