Intel Core i5-8400B Benchmark, Test and specs

The Intel Core i5-8400B has 6 CPU cores and can calculate 6 threads in parallel. The clock frequency of the Intel Core i5-8400B is 2.8 GHz and turbo frequency for one core is 3.8 GHz. The number of CPU cores greatly affects the speed of the processor and is an important performance indicator.

The Intel Core i5-8400B has integrated graphics, called iGPU for short. Specifically, the Intel Core i5-8400B uses the Intel UHD Graphics 630, which has 192 texture shaders and 24 execution units. The iGPU uses the system's main memory as graphics memory and sits on the processor's die.

A photo or video codec that is accelerated in hardware can greatly accelerate the working speed of a processor and extend the battery life of notebooks or smartphones when playing videos.

The processor supports a maximum memory capacity of 64.0 GB distributed across 2 memory channels. It offers a peak memory bandwidth of 42.7 GB/s. Both the type and quantity of memory can have a substantial impact on the overall system performance.

The processor has a thermal design power (TDP) of 65 W watts. TDP indicates the cooling solution needed to effectively manage the processor's heat. It generally provides an approximate indication of the actual power consumption of the CPU itself.

The Intel Core i5-8400B is manufactured using a 14 nm process. A smaller manufacturing process indicates a more contemporary and energy-efficient CPU. In total, this processor boasts a generous 9.0 MB cache. A substantial cache can significantly enhance the processor's performance, particularly in scenarios like gaming.
