CM Posted October 7, 2016 Share Posted October 7, 2016 Hi I currently have an external gtx 970 running on the akitio powered by the dell 220, Thunderbolt to macbook pro. But I'm now considering a dual setup by buying a gtx980 ti and just have one power supply and hopefully a better case to house both cards running x2 thunderbolt cables to my macbook pro. Does anyone have any experience of doing this? Thanks Quote Link to comment Share on other sites More sharing options...
devild Posted October 7, 2016 Share Posted October 7, 2016 if you have 2 thunderbolt ports on your mbp, then there shouldn't be any problem. I can confirm that 2 akitio box are working with mbp late2013 and macpro 2013 'trashcan'. Quote Link to comment Share on other sites More sharing options...
Tech Inferno Fan Posted October 7, 2016 Share Posted October 7, 2016 A 15" MBP hosts it's dual-Thunderbolt ports controller down a single x4 2.0 link. Adding a second card would increase processing power but if both cards are working at the same time then they share the x4 2.0 bandwidth. Consider offloading the GTX970 and purchasing a GTX1080. That would then give you about 23% less processing power than the GTX970+980Ti all the while having exclusive access to the x4 2.0 bandwidth within a single AKiTiO enclosure. 1 Quote Link to comment Share on other sites More sharing options...
CM Posted October 8, 2016 Author Share Posted October 8, 2016 thanks, @Tech Inferno Fan @devild for the information, I might just update the single card at some point, but ill need cuda cores the most for GPU rendering so I will probably go with the gtx980 ti as it seems to have the most cores for the cost.

Dschijn Posted October 12, 2016 Share Posted October 12, 2016 2 cards would only make sense for rendering apps. Don't consider it for games. Any normal gpu calculation app will work very well with the TB2 bandwidth. Quote Link to comment Share on other sites More sharing options...
