Information on Athlon X4 840 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.
|Thermal design power (TDP)||65 watt||of 400 (Xeon Platinum 9282)|
Supported virtual machine optimization technologies. Some are specific to Intel only, some to AMD.
Single-core and multi-core benchmark results of Athlon X4 840. Overall benchmark performance is measured in points in 0-100 range, higher is better.
This is our combined benchmark performance rating. We are regularly improving our combining algorithms, but if you find some perceived inconsistencies, feel free to speak up in comments section, we usually fix problems quickly.
Passmark CPU Mark is a widespread benchmark, consisting of 8 different types of workload, including integer and floating point math, extended instructions, compression, encryption and physics calculation. There is also one separate single-threaded scenario measuring single-core performance.
Let's see how good Athlon X4 840 is for a gaming PC, compared with system requirements of some popular titles. Remember that sometimes official hardware requirements may reflect real performance inaccurately.
