6xGTX 780 6G - GPU processor OCed by 200 MHz - air cooled

DL - 126.37 Ms/sec
PT - 103.03 Ms/sec

PathTerm = 1 and Coherent Ratio = 1.

1xGTX780 6G - 200 MHz overclocking - air cooled

DL - 22.21 Ms/sec
PT - 19.47 Ms/sec

PathTerm = 1 and Coherent Ratio = 1.

Tutor,

DL should be higher - around 300.

Nice temps at 1123mhz core clock. Do you have extra space between cards? Are you using raisers?

Thanks Smicha for your observations. That was my thought also. I'll soon be water-cooling these GPUs also.

The cards were all packed closely together. I don't have any raisers. The temps are low because these GPUs are in a Tyan server that has that characteristic wind tunnel cooling.

Nice to compare the 780Ti with TitanZ:

PT, Alpha shadows off (>15000 s/px):
path term power 1 , coherent mode on
test done twice

2x TitanZ: 43.30 Ms/sec (around 15000px), 3:09 sec for 16000px
3x 780Ti: 45.34 Ms/sec (around 15000px), 3:30 sec for 16000px
You can see that MS/sec does not say much, because this numter is changing during time.
Therefor the total rendertime , i.e. 16000px is a better number to compare.

Both setups have a slot space between the cards and therefor a very good airflow
Looking at the numbers he 780 Ti is really a winner (compare 3gpu of the 780 with 4gpu of the Titans)... if 3gb is enough and if you can have them in a case with a slot space between the cards!!!!

cheers,

Rappet,

What are core and mem. clocks - these are important for comparisons.

for a 6g gtx780ti,a friend of mine said will ship in 2015/4 or 2015/6(by NV factory OEM,in fact,he is one of the stuff)
it's now can purchase a gtx780ti-6g in China OEM about 3000CNY(about 480$), and this is real,because I saw the real card and the GPU-Z snapshot!
Can't post here sorry guys!
But it worth a wait right? Damn~ just can't let the Titan black breath huh

Kevin, thanks for sharing. That's interesting. Would be interesting to see the ms/$ ratio comparison between that card & the rest of the new 2015 lineup.

I don't know where from You got this, but 770, 780, 780Ti was discontinued (in nvidias Game24 event). 9xx based on new Maxwell architecture line is already in production.. How on earth nVidia is going to to make 6GB Ti & for what reason they would get already discontinued numbering up? Wouldn't that be stupid?

You "saw" real card & GPUZ etc..it's available for purchase & You can't write anything here..- well, I haven't read more nonsence in a single line for a long time =) sorry to come with this but You read too much rumors..& that not an information..Just dreamy thoughts..

Hi Smicha,
Juste added the numbers on the 2x Titan Z to compare (few posts back)
greetz,
