GC (idle) is goroutines doing GC marking because there is no other work for the program to do. GC (dedicated) is goroutines dedicated to doing nothing other than GC marking, for at least the current GC cycle. The number of goroutines put into this mode depends on how hard the GC has to work to keep up with memory being allocated by the rest of the program.
