Intel Core i3-12100 vs Core i5-12400
A side-by-side comparison of specs, performance and value. The Intel Core i3-12100 is a 4-core, 8-thread desktop processor introducing the Golden Cove architecture to the budget segment, featuring DDR4/DDR5 support, PCIe 5.0, and a bundled Laminar RM1 cooler.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles everyday office tasks and web applications with ease, but heavy multitasking will expose the 4-core limitation.
Snappy and reliable for all standard desktop applications.
Gaming
Delivers playable 1080p frame rates in esports and older AAA titles when paired with a mid-range GPU, though 4 cores limit performance in modern CPU-heavy games.
Fantastic gaming performance that punches well above its weight class.
Virtualization
Can run a single lightweight virtual machine, but lacks the core count for serious virtualization workloads.
Very capable for homelab and development VMs.
Efficiency
Very power-efficient for a desktop processor, drawing little power at idle and scaling linearly under load.
Highly efficient 65W design with minimal heat output.

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.
