In the GPU’s SIMT (Single Instruction Multiple Thread) architecture, the GPU streaming multiprocessors (SM) execute thread instructions in groups of 32 called warps. The threads in a SIMT warp are all of the same type and begin at the same program address, but they are free to branch and execute independently.

Not all threads will execute in lockstep but they are split into groups whose threads are locked to each other. This means that if only 1 thread out of all threads enters a branch then only 1 group will need to enter that branch while all the others will skip it. In that group that has to execute both branches it will actually execute ...
