i still couldn't find exact solution. lets assume that i patched File1.exe with x64dbg and saved, i want to compare file1.exe and patchedfile.exe by looking through jmp je mov dissasembled sections.

You shouldn't use a debugger to do this, use a diff tool instead. These are some tools that can compare binary files:

These tools only compare the differences in bytes without disassembling them, but knowing the offsets of the differences you could easily take a look at the opcodes in x64dbg.

There is also an IDA plugin for this: patchdiff2, although I haven't tried this one. You can also consider writing your own x64dbg plugin, it shouldn't be too hard.
