How we picked the best CPU for RTX 3090
To select the best CPU for the NVIDIA GeForce RTX 3090, your first step should be to determine the budget. High-end CPUs can be expensive, so it’s important to have a clear budget in mind to narrow down your options. Once you have a budget in mind, you can start considering other factors.
The next step is to check for compatibility. Make sure the CPU you choose is compatible with your motherboard and has the appropriate socket type. The RTX 3090 requires a PCI Express 4.0 slot. Additionally, consider the clock speed of the CPU. It should be high enough to keep up with the RTX 3090’s performance demands, with a minimum of 3.0 GHz being recommended. The more cores a CPU has, the better it will perform with the RTX 3090. A CPU with at least 16 cores is recommended. Consider the power consumption of the CPU, with a TDP that matches or is lower than the GPU being recommended to avoid overloading the power supply. Check for overclocking support, as overclocking can improve performance but also increases power consumption and heat output. Finally, look at the brand reputation and choose a well-known brand with a good reputation for quality and support.
