Core i5-8400 vs Core i3-1125G4 benchmarks

In our benchmarks, the Core i5-8400 beats the Core i3-1125G4 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-1125G4 in all gaming tests too.

With info from our database, we find that the Core i5-8400 has significantly more cores with 6 cores whereas the Core i3-1125G4 has 4 cores. Despite this, the Core i3-1125G4 has more threads than the Core i5-8400. The Core i3-1125G4 outputs less heat than Core i5-8400 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
