Got a reply from scan.co.uk about which version of Open cl there latest Pascal GPUs have.
[1080 /Titanx and there Pro versions P5000 P6000].
scan.co.uk contacted Nvidia on my behalf and Nvidia replied saying that "We can confirm NVIDIA are still using OpenCL 1.2"
Thanks for all the extra detail and advisory info you posted. All noted.
As for your advice to wait for the GTX 1080Ti and there will be new AMD HBM2 cards .
It seems were always waiting for stuff to come out its an endless waiting game.
Still ill wait a bit longer and see what the GTX 1080Ti and AMD cards have to offer.
I thought so NVIDIA will be supporting right now OCL 1.2 as it makes more sense for them,until OCL 2.0 will be supported by more and more SW or rather they want protect their CUDA API
Regarding the GTX1080 or get Titan X Pascal or P6000/P5000,right now I've ZOTAC GTX 1080 AMP! edition which I got,in Poser Pro 11 not sure,performance with Titan X in tandem and rendering,not sure,its not faster as I thought so,SuperFly engine still doesn't taking full advantage of GPU used and still there is room for improvement,temps I'm getting pretty much in 65C range as max with 65% and card is very.very quiet
I would expect there will be Ti version,as Ti usually is released after Titan version and usually is cut down Titan with less memory and less CUDA cores,but performance should be on par with Titan X Pascal
New GTX1080 is faster than old Titan X,be warned,Scan and many other companies only sells old Maxwell Titan X,Pascal Titan X is only can be bought through the NVIDIA website
Regarding what new GPU will bring us,hopefully if AMD will come with their GPU,those GTX10xx prices will drop to more reasonable levels as right now are overpriced and I would wait there for bit longer if you could,if not then I would pick up GTX 780 6GB version or GTX Titan X or GTX 980Ti which can be bough right now used for very reasonable money and those newer GPU don't have failure rate as those which has been manufactured previously and mostly many companies have great RMA
Hope this helps
