What is differance from this two Windows64 builds?
Win64-cuda vs Latest-win64?
Win64-cuda and latest-win64
Win64-cuda and latest-win64
On speed or what else?

The difference is that with the first two builds you can choose GPU-based render engines (e.g. PathOCL), having much better performance in many cases.
The first build has Cuda enabled: you can use it if you have a suitable Nvidia GPU. Many users reported better performance using the Cuda build with Nvidia GPUs instead of the more generic OpenCL build.
The second build has OpenCL enabled, but not Cuda: you can use it with any GPU, either Nvidia or AMD.

The third build does not have any GPU acceleration enabled: you can only choose CPU-based render engines (Bidir, PathCPU), but it will run basically on any PC, even a laptop with very low-end graphics card, where probably no GPU acceleration support is available.

I would assume that
- Win-64 is CPU only and doesn't require OpenCL or CUDA installed
- Win-64-OpenCL is CPU and OpenCL, and wouldn't require CUDA installed
- Win-64-Cuda is CPU, OpenCL and Cuda and requires CUDA drivers installed.

3rd build: is it supported SEE3.X for OIDN or is it need at least SEE4.1?

SEE4.1 is a ODIN library requirement (not a LuxCore one) so it is needed by all versions.

Ok. I understand now ;)
