Verdict

The Intel Core i5-12400 is a highly efficient 12th-generation Alder Lake desktop processor featuring 6 Performance cores (P-cores) and 12 threads, with a base clock speed of 2.5 GHz and a max turbo boost of up to 4.4 GHz. Built on the Intel 7 process with an 18 MB Smart Cache and a 65W TDP (117W max turbo power), it supports both DDR4-3200 and DDR5-4800 memory alongside PCIe 5.0 connectivity on the LGA 1700 socket. Its primary pros include exceptional price-to-performance value, strong single-core gaming performance that often rivals more expensive competitors like the Ryzen 5 5600X, and the inclusion of integrated UHD Graphics 730 and a stock cooler. However, its main cons are the lack of hybrid architecture Efficiency cores (E-cores) found in higher-tier Alder Lake chips, a locked multiplier that prevents traditional overclocking, and an included stock cooler that can become noisy under heavy loads.
