Our Verdict on Each
An excellent choice for mid-range gaming and productivity, offering good single-core speeds, PCIe 4.0, and integrated graphics for troubleshooting.
Best for: Building a mid-range gaming PC on the LGA 1200 platform.
Read the full reviewAn exceptional value desktop CPU that brought PCIe 4.0 and strong IPC to the budget market.
Best for: The Intel Core i5-11400 remains an incredibly smart purchase for budget PC builders, especially on the used market. If you are assembling a 1080p gaming rig or a general-purpose home PC and want to keep costs low, this processor offers phenomenal value. Its 6-core, 12-thread configuration is more than sufficient for modern games when paired with a mid-range GPU. Because it is not unlocked, you should pair it with a B560 or H570 motherboard to at least allow memory overclocking, maximizing its potential. However, if you are buying brand new components, you might find better overall efficiency and upgradeability with a 12th Gen Alder Lake i5-12400F or a Ryzen 5 7600. Still, for under $100 on the secondhand market, the i5-11400 is an absolute steal that will comfortably handle everyday computing and mainstream gaming for years to come.
