OCTANE BENCHMARK: Submit performance scores for your rig!

Wed Mar 04, 2015 12:21 am

Dear Friends!!

It's a great topic!

Can we sum up if with OCTANE 2.21.X the performance of GTX 980 is better than GTX 780?
Does new OCTANE kernel supports advantages (if there are any) of Maxwell??
Are there any future plans (and possibilities) to get more performance from Maxwells?

I'm just in decision making moment and have to chose between 780s or 980s.

All Best,

Raffael,

My opinion/experience is that in Octane, GTX 980 is about equal to regular 780. 780 6G is faster than them both. The 2013 Titan (it's a 6G card) is a little faster than the 780 6G. The GTX 780 TI is faster than those four GPUs. The GTX 780 TI ACX SC OC is faster still. GTX Titans (Blacks and Zs) have 6G (which is better for 4k/large format rendering because of card's memory size) and both of those are faster than the 780 6G, 2013 Titan and are approximately on par with the 780 TI ACX SC OC, except the Z has two processors, so both of them together make the Z about twice as fast. None ACX SC OC 780 Ti's are likely not quite as fast out of the box because of chip selection/binning. Of course, others' experience/opinions may differ.

P.S. Also, see spreadsheet here - https://spreadsheets.google.com/spreads ... utput=html . Also, I purchased a GTX 980, but quickly sold it to a gamer.

I completely agree with Tutor. If you are rushing with 980 just wait about 2-3 weeks for news from nvidia side. We all hope to see a new titan generation soon. But if you can get 780 6GB anywhere just grab them.

If I were to be more precise: 780, 780Ti, Titan, Titan Black, Titan Z are made on the same GK110 chipset, so their specs differ primarily by number of cuda cores. From my statistical inference (my signature and the attachment) we know that Octane speed comes in 1/4th from memory clock, and in 3/4th from core clock (useful info for OC). Hence theoretical comparison between all GK110 chipset-based cards may be given by (base clock used, divided by 1e10):

780: 2304*6000*863 = 1.19 => 100%
780Ti: 2880*7000*875 = 1.76 => 148%
Titan: 2688*6000*837 = 1.35 => 113%
Titan Black: 2880*7000*889 = 1.79 => 150%
Titan Z: 5760*7000*705* = 2.82 => 238%

Now if we assume that 980 performs close to 780 you may find these relative indicator useful. Bear in mind that watercooling may give much better results, i.e., 780 6GB runs at 1300 mhz core and 7000 memory, so in theory it is 75% faster than in base clock (measured 45% faster than a 4-way setup on air cooling with no extra space between cards).

Thank You!!

You reaction and will of help is great!!!

Now everything is clear. I would go for 780 STRIX 6GB VRAM or wait for GTX 980 with 6GB VRAM.

Can anybody from OTOC say something of possible future advantages of Maxwell GPU's?

We finally got around to release the OctaneBench tool, which hopefully will simplify benchmarking a bit more and make it more consistent. Please use this one for future benchmarking

Abstrax,

Thanks for new OctaneBench utility. I'll be using it to fine-tune my GPUs for Octane.

Best of my 3 scores running 8xGTX 780 TI ACX SC OCs = 889.521069.

Best of my 2 scores running 1xGTX 780 TI ACX SC OC = 114.511415.

When yesterday I saw the score I thought to myself - 'this could only be Tutor'

What are core clocks for Ti to get 114? And temps? On my single titan (not black) (water) I can go even to 112-115.
