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 review

One 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.
