Our Verdict on Each

The i3-12100 delivers exceptional single-threaded performance for its $122 price point, complete with an iGPU and a stock cooler, making it one of the most well-rounded budget desktop processors Intel has ever produced.

Best for: Buy the i3-12100 if you are building a budget desktop PC and want the peace of mind of having integrated graphics as a fallback, or if you do not plan to install a dedicated GPU. At its current street price, it is an excellent choice for office PCs, student workstations, and entry-level gaming rigs paired with a mid-range graphics card like the GTX 1660 Super or RX 6600. Avoid it only if you are certain you will never need the iGPU, as the 12100F offers identical CPU performance for less money.

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.
