Four neighboring texels. One gather.
Texture sampling usually returns one filtered value. Gather reads a four-texel neighborhood from a selected channel, then the same operation can compare a depth texture against a reference.

The selected channel is a compile-time gather index; graph rebuilds make that boundary explicit.
Texture gather issue.
Change the channel or offset, rebuild the node graph, and compare the two backends.
