You mean this thread E-Cycles - Faster cuda rendering - General Forums / Latest News - Blender Artists Community which it says “Faster Cuda rendering” right in the title? And I have a table with all the timings on Vega64 and 1080Ti ? I don’t know how to make it clearer than by naming the thread like that, but if you have a precise proposition, I’m open.
Edit: Yep, in this thread I wrote GPU rendering, I corrected it. Although it’s also true for OpenCL, I agree 15% faster isn’t worth mentioning it.
