Whatis more important in GPU Cuda Cores or Memory Bandwidht?
Posted: Tue Dec 04, 2012 8:00 pm
Today I have a GT240 which does not improve NV performance anyway.
In my researches I found the GTX660 the best price performance GPU. But my current PSU is not powerful enough for it and change the PSU will be expensive, so I started to consider the new GTX650Ti
I read here in the forum the GTX560Ti alone is 5.15 fps and I am considering it as a base for comparison, using the nvidia specifications and some review benchmark results, so:
considering only the cuda cores, the 650ti will be 15% slower = 4.48fps
considering only the memory bandwidth the 650ti will be 49% slower = 3.45fps
I would like to ask if someone knows what would be real results, will the cuda cores have more influence in performance or will the memory bandwidth hurts it more?
thanks.
