Did you take into account the GPU frequency ?

[Charlo06]

Hey guys,

I'm looking at moving away from vray and can't wait to get my hands on octane render 2.0!!

I haven't got the best GPU yet so the octane demo didn't run too well on my machine but from what I could tell octane has awesome potential..

I just want to know, do you guys favour Nvidia cards over AMD? I'm looking at buying the new AMD r295x2 card (maybe even 2 of them ) but I don't know whether to wait for the Titan Z from nvidia?!?

I create architectural cgi and need a card that can deal with relatively heavy scenes/ typical interiors..

Any advice would be much appreciated!

Cheers,
Andy

no. Neither memory issues. as it says, cuda cores X buck. so it's just a rough thing which doesn't necesarily reflect rendertimes per se. feel free to add other metrics.

Added another metric: cores(bang) per Euro(buck)...made better sense to me ...
I also added another decimal place to original numbers, since it seemed relevant for most of them.

I might get this into Excell at some stage and make a factor relating to cores*Mhz, add 'street price AU' and watts - for the greenies*

*like me

EDIT: also, 750Ti is 2gb - certainly all the variants I've seen...

This type of Data can be misleading because not all cores are created equal.

What is more important, is what the Ms/s you get in the benchmark scene.
Of course, each manufacture will give you varying lvls of OC to the CUDA cores, so we even need a benchmark for each card and manufacture...

Step 1: just the reference designs, with a ghz*cores factor - all Ghz listed are reference clocks (Base) not 'turbo boost' or whatever. CAN any of these run at boost clocks for long durations on air?
'street price' is the lowest reputable (non-grey import) etailer I could find from staticice, and
second hand prices are from sold&completed listings on ebay. NOTE:, a few of the prices were outliers - namely the gtx780 @ $500 (most prices $550 & up), and the 770 2gb (most started at $370+...)


I think you have a good point though, I'll add manufacturers, with each manufacturer clock later... if we can get some idea about how often the cards run at boost clocks I'll consider changing the Ghz to the boost clocks too...

Edit: the yellow are ones I'm considering for my new build... prob leaning towards the second hand 2x gtx780's (don't judge - I'm on a tight budget) hopefully the 780 6gb is released son and the 3gb prices will drop...

Fixed the incorrect titan VRAM, and added boost (reference) clocks, Core Ghz factor, and the coreGhz per unit of currency

Rev 3.

added the overclock boost clocks from gigabyte (because their website was easy to get the data out of quickly)

Dropbox link to the file if anyone wants it. can change prices and clocks as you see fit

Wow, that's a lot of work.

Now the one thing it is missing is the Octane Benchmark score.
I can tell you that I just bought this card:

And out of the box, I get 8.25 Ms/s in PT.
