In addition, most gamers can benefit from overclocking to improve system and game performance. So, before buying the product, check the discussed features carefully.  

Thermal Design Power

Before choosing a CPU, you need to learn about Thermal Design Power (TDP), sometimes known as a CPU’s power consumption.

It depicts the maximum amount of heat a CPU is expected to generate when subjected to high workloads. While low TDPs are generally preferred, CPU coolers can help you deal with larger TDPs as well. Choose a CPU with a lower TDP if you don’t want to spend money on coolers. The wattage is clearly stated on the product’s specification sheet.
