Dual K6000 vs Single M6000

[majush]

Wondering if anyone who have these two diff cards can give us a comparison on performance. Or if AD have any resources on performance, can share a bit of info. Wondering what is worth buying. Can get 2xK6000 from ebay for the price of 1xM6000 and am seriously thinking about investing in a Z840 for the flame I am hoping to subscribe before 2015 ends. 

thanks

Hi,

There is no existing comparative benchmark for the NVidia K6000 and M6000 we can share.

As you know already, the NVidia M6000 has more cores and a higher memory bandwidth rate, which give better loading and interactivity performance within our applications.

About if one M6000 is better than two K6000, this all depend on your workflow and needs.

The second graphic board in Flame is used for background rendering (local "under the hood" render) and for GPU debayering.

All other operations are processed on the main graphic board.

So if you are looking for better application performances, the M6000 is the logical choice.

If your workflows highly involve GPU debayering (RED and ARRIRAW) and background rendering, the K6000 configuration is a suitable option.

Hope it answers the questions,

Regards,

Yann

Thanks Mr. Yann. That clears my doubt. I was under the impression that both cards work together. Thanks for clarifying.

But that brings in another doubt. Is it essential to have 2x M6000 for background rendering?? Or 2 different cards can achieve the same? So a M6000 for application performance and a titanX/K6000 for background reactor? SLI needed?
Thanks

You will need to run the cards in pair.  So you would be using 2 (x) K6000 or 2 (x) M6000.  Not 1 (x) K6000 + 1 (x) M6000.

Thank you. 🙂

m6000 is less than 20% faster for double the price. But one K6000 and wait 6 months for the next nvidia bump.

Its worth waiting to see what the hardware list is from AD, if it supports Titan z then its a no brainer.

From what I gather from the other thread, there is no hw restriction but only certified hw/recommendation. So Titan Z/X must be supported except that you dont get 10bit UI and the special drivers for it in linux.

Hi,

As mentioned, there is no HW restriction for Flame starting with 2016 Extension 2.

We will provide a list of recommended hardware for which stability and performance will be certified.

The Titan X and Z will not be part of the recommended hardware list, thus not officially supported.

Also, please keep in mind that running Flame on non-recommended hardware will void your Technical Support assistance as we cannot guarantee the way the application will act on non-recommended hardware.

So, just to be sure we are clear, we can phrase the Titan support for Flame this way: possible = yes, recommended / supported = no.
