Comparing GPU performance using Blender benchmarks
If you ever need a rough estimate of the performance of one GPU versus another, I recommend checking out Blender’s benchmarks.
Their benchmarks are of course not perfectly transferable to other applications, but it gives a decent estimate for the order of magnitude. For instance, if you know the performance for your application on an RTX 3060 and want to know how the same algorithm will perform relative to that, this should give you an indication.
