<br>Hi, i ve made a lots of testing about this, and actually the gk104 gpu familly is really weak on double precision opérations...<br>So, every 6xx gpu are slower than 5xx ... 5 cores of 6xx = 1 core of 5xx in double...<br>Only one version of blender on graphicall have succeded to run cycles on an Asus 680 dcuii , but i ve also made some tests with iray and other gpu renderer... It s the same...<br>Nvidia have said that the first kepler 2 will come with the tesla k20, and new quadro and gtx after... 6 month to wait minimum...<br>So i ve built for a little studio a rendering machine with 4 580 gainward phantom 3 go, and i think it s the better price/speed actual solution...<br>But i think that Brecht will say more about this. ( don't think that s possible to convert everything in single précision )<br>Regards...<br>Myke<br><br><br><div id="htc_header" style="">----- Reply message -----<br>De : "Matej Mo" <mo.cgraphics@gmail.com><br>Pour : <bf-cycles@blender.org><br>Objet : [Bf-cycles] Cycles on Nvidia Kepler<br>Date : mar., sept. 25, 2012 09:29<br><br></div><br>Hi!<br><br>I'm interested to know if Cycles works on Kepler arhitecture (6xx series) and if there are any benchmarks that would show a comparison in speed with Fermi (say a 680 vs a 580). <br><br clear="all">If Cycles doesn't work on Kepler cards, could you estimate when such support will be added?<br>
<br>I need to buy a new render card, since my last one died and the decision which one is a lot dependent on how (if) it works with Cycles.<br><br>Regards!<br><br>-- <br>Matej Mo, freelance CG artist<br><a href="http://matejmo.deviantart.com/gallery/" target="_blank">http://matejmo.deviantart.com/gallery/</a><br>
