1Managed ByGoroutine methods are managed by golang runtime.Thread are managed by operating systems.
2Hardware dependencyGoroutine are independent to hardware.Thread are dependent on hardware.
3Communication MediumGoroutines uses channels as communication medium.Thread have no easy communication medium.
4LatencyGoroutines can commuicate with other routines with low latency.Thread as have no communication medium, communicate with other thread with high latency.
5IDGoroutine does not have any thread local storage and no unique id.Thread have thread local storage and have unique id.
6SchedulingGoroutines are co-operatively scheduled.Threads are preemptively scheduled.
7StartupGoroutines have faster startup time.Threads have slower startup time.
