Hi all i was browsing and realised the 1070 is seriously bottlenecked

Something im not sure if it vram bandwith or something else.

Do you have any idea what can make them as bad?


Here they compare average ppd

So it kinda make 1070 sli worthless if 1 1080 can make as much as 2 1070...

My average was that aswell untill I overclocked my memory by 625mhz:

 

P11402 - R2, C15, G190
1911/7604
685.000PPD
 
2021/7604
714.000PPD
 
2021/8856
745.000PPD 

 

Increasing your memory clocks on your 1070 (which shouldnt be any issue) resulted me anywhere from 20-40k more PPD on my units.

I told everyone that nvidia is laughing at us.. they sell memory bottlenecked gpu to make next release seem better.


intel did that the other ways with cpu..

little ipc increase but ways higher ram bandwith giving higher benchmark.




Anwyays im still going to get a gtx 1070. the strix.



Kinda in need of horsepower with my single 7950

What do you mean with this?

 

You can easily get 500mhz more out of your memory clocks and gain PPD :D

I mean new gpu higher price and as low bandwith as last gen gddr5. We need to overclock it to gain performance. But i wonder what would have happened with hbm and 512gbs + maybe 50% more performance biggrin.gif

Just ordered a strix 1070. I do want to overclock the vram as high as i can smile.gif

I also ordered some AIO watercooling to put on there. Because thermals throttle the clocks.

 

70c = 2050 core clock

76c = 2000 core clock

 

So higher temps let the card boost less high. So I hope with water i can go perma 2100+

Those new throttling thing are kinda boring.
