- arcanus 10y ago> Xeon Phi have got more cores, 50 or 60, and the cores share memory 60 cores. Furthermore, the cores have multiple (4) hardware threads per core. So on the latest Phi (Knights Landing) you can have several hundred threads (240) running concurrently without contention (in principle).
