Our Verdict on Each

A highly cost-effective 6-core CPU that delivers excellent value for 1080p gaming and general computing, despite its locked multiplier and older 14nm process.

Best for: The Intel Core i5-10400 is highly recommended for users building a budget to mid-range 1080p gaming PC or a general-purpose home/office computer. Its 6-core, 12-thread configuration provides excellent longevity for everyday tasks, light content creation, and modern gaming when paired with a mid-range GPU like an RTX 3060 or RX 6600. The inclusion of UHD 630 graphics means the system is functional even if a discrete GPU fails or is delayed in purchase. Because it is a locked processor, there is no need to invest in expensive Z-series motherboards or high-end cooling; a simple B460 board and the stock cooler are sufficient. This makes it an ideal choice for budget-conscious buyers who prioritize stability, reliability, and maximum value over enthusiast-level tweaking or extreme frame rates.

Core i5-11400Recommended

An 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.
