Compatibility

Information on EPYC 7702 compatibility with other computer components and devices: motherboard (look for socket type), power supply unit (look for power consumption) etc. Useful when planning a future computer configuration or upgrading an existing one. Note that power consumption of some processors can well exceed their nominal TDP, even without overclocking. Some can even double their declared thermals given that the motherboard allows to tune the CPU power parameters.

Number of CPUs in a configuration	2 (Multiprocessor)	of 8 (Xeon Platinum 8454H)
Socket	TR4
Power consumption (TDP)	200 Watt	of 500 Watt (Xeon 6960P)
