LGA 1700 desktop processor

The Intel Core i5-12400 is a 6-core, 12-thread desktop CPU built on the Alder Lake architecture using Intel 7 process technology. It operates at a 2.5 GHz base frequency and can reach a 4.4 GHz maximum turbo frequency. The processor includes Intel UHD Graphics 730 and supports both DDR4 3200 and DDR5 4800 memory in dual-channel mode. Total cache comprises 7.5 MB L2 and 18 MB L3.

Suitability and alternatives

This CPU suits builders targeting a 65 W base power platform with PCIe 5.0 support for graphics and storage. It provides 16 CPU PCIe 5.0 lanes and 4 CPU PCIe 4.0 lanes for modern expansion. Systems requiring more than 6 cores or higher sustained multi-thread throughput should consider a higher-tier model. A discrete graphics card is recommended for demanding 3D workloads.

Deciding specification

The LGA 1700 socket defines motherboard compatibility and cannot be changed later. This processor will not install in boards with a different socket. Maximum memory capacity is 128 GB with a peak bandwidth of 76.8 GB/s. Processor base power is 65 W and maximum turbo power is 117 W.
