may be GTX780 faster than a 1080 for next reason gtx780 have GK110(Kepler) stone and 1080 GP104-400 Pascal (architecture) and Cuda cores are not the same.acasta69 wrote: ↑Wed Apr 29, 2020 6:51 amneo2068 wrote: ↑Mon Apr 27, 2020 6:21 pmI get errors with latest build and OpenCL and the food demo scene, too, e.g. PATHOCL:clFinish(CL_INVALID_COMMAND_QUEUE) or TILEPATHOCL: clEnqueueReadBuffer(CL_OUT_OF_RESOURCES). With cuda my GTX 780 is 1.5 times faster than the GTX 1080. Is it normal behaviour?It seems we have a wide variety of results, mostly improvements but not all of them.
Also a GTX780 faster than a 1080 is quite strange, isn't it? The 1080 has more Cuda cores and nearly double clock speed and memory bandwitdh than the 780.
Such case was happend earlier
1 core Fermi = 3 cores Kepler
