Intel Xeon E5-2650 v2 vs E5-4640 v3
Comparing Xeon E5-2650 v2 and Xeon E5-4640 v3 processor market type (desktop or notebook), architecture, sales start time and price.
Xeon E5-2650 v2 and Xeon E5-4640 v3 basic parameters such as number of cores, number of threads, base frequency and turbo boost clock, lithography, cache size and multiplier lock state. These parameters indirectly say of CPU speed, though for more precise assessment you have to consider their test results.
Information on Xeon E5-2650 v2 and Xeon E5-4640 v3 compatibility with other computer components: 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.
