Compatibility
Information on Athlon 850 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 | 1 | of 8 (Xeon Platinum 8160M) |
| Socket | A | |
| Power consumption (TDP) | 47 Watt | of 400 (Xeon Platinum 9282) |
Memory specs
Types, maximum amount and channel number of RAM supported by Athlon 850's memory controller. Depending on the motherboard, higher memory frequency may be supported.
| Supported memory types | DDR1 |
