Intel Core i9-10900 vs Intel Core i5-12400

Core i9-10900 vs Core i5-12400 benchmarks

In our benchmarks, the Core i9-10900 beats the Core i5-12400 in overall performance. Despite this, the Core i5-12400 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Core i9-10900 has significantly more cores than the Core i5-12400. Indeed, the Core i9-10900 has 10 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 i9-10900 has a slightly higher clock speed than the Core i5-12400. Also, the Core i9-10900 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 i9-10900 has more threads than cores. Each physical core is split into multiple threads.
