Intel Core i5-12400 vs Intel Core i9-12900

Core i5-12400 vs Core i9-12900 specs and performance

According to the hardwareDB Benchmark tool, the Core i9-12900 is faster than the Core i5-12400. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-12400 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i9-12900 has significantly more cores than the Core i5-12400. Indeed, the Core i9-12900 has 16 cores compared to 6 cores found in the Core i5-12400. It also has more threads than the Core i5-12400. With our hardware info, we find that the Core i5-12400 has a slightly higher clock speed than the Core i9-12900. Despite this, the Core i9-12900 has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i5-12400 has more threads than cores. Each physical core is split into multiple threads.
