CPU Comparison
Core i5-11400 vs Core i5-12400
A side-by-side comparison of specs, performance and value. The Intel Core i5-11400 is a mainstream desktop processor that brought next-generation features to the budget segment with the Rocket Lake-S architecture. Launched in March 2021, this 6-core, 12-thread chip operates on a 14nm process but utilizes the Cypress Cove microarchitecture to deliver improved IPC over the 10th Gen. With a base clock of 2.6 GHz and a boost up to 4.4 GHz, it offers solid performance for both gaming and productivity. The standard 65W TDP makes it compatible with a wide range of cooling solutions. A major highlight is the inclusion of 20 PCIe 4.0 lanes, enabling faster storage and GPU communication without stepping up to a more expensive motherboard. The integrated UHD Graphics 730 provides basic display functionality, though it is not intended for gaming. For budget-conscious builders, the i5-11400 became an instant favorite, offering an unbeatable price-to-performance ratio that made it a staple in entry-level gaming rigs and home office builds.

Our Verdict on Each
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.
