Our Verdict on Each
A solid hexa-core processor that offers slightly higher out-of-the-box clocks than the 8400, making it a great choice for budget gaming and office builds.
Best for: Upgrading an older LGA 1151 system on a budget, or building an office/HTPC machine.
Read the full reviewOne of the best value gaming CPUs of its era. By removing the iGPU, Intel lowered the price, making it a top choice for budget builders with a dedicated graphics card.
Best for: Building a budget 1080p gaming PC using the used market, where a dedicated GPU is already owned.
