Core i5-12400

Our Verdict on Each

The i3-12100F is one of the best value processors Intel has ever produced for gamers. By removing the iGPU and dropping the price to $97 while keeping the outstanding Golden Cove cores, it dominated the budget build market in 2022.

Best for: The i3-12100F is the optimal choice for anyone building a dedicated gaming PC on a strict budget where a discrete graphics card is guaranteed. By saving $25 over the 12100, you can allocate those funds toward a better GPU, which will have a far greater impact on gaming frame rates than the integrated graphics you are giving up. Do not buy this processor if there is any chance you will need to run the system without a dedicated GPU, as a missing or failed graphics card will render the computer completely unusable.
