Intel Core i5-8400B vs Intel Atom D2550

The Intel Core i5-8400B is a 6 core processor with a clock frequency of 2.80 GHz (3.80 GHz). The processor can compute 6 threads at the same time. The Intel Atom D2550 clocks with 1.86 GHz, has 2 CPU cores and can calculate 4 threads in parallel.

Processors with the support of artificial intelligence (AI) and machine learning (ML) can process many calculations, especially audio, image and video processing, much faster than classic processors. Algorithms for ML improve their performance the more data they have collected via software. ML tasks can be processed up to 10,000 times faster than with a classic processor.

Graphics (iGPU) integrated into the processor not only enable image output without having to rely on a dedicated graphics solution, but can also efficiently accelerate video playback.

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.

Up to 64 GB of memory in a maximum of 2 memory channels is supported by the Intel Core i5-8400B, while the Intel Atom D2550 supports a maximum of 4 GB of memory with a maximum memory bandwidth of 8.6 GB/s enabled.

The Intel Core i5-8400B has a TDP of 65 W. The TDP of the Intel Atom D2550 is 10 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The Intel Core i5-8400B has 9.00 MB cache and is manufactured in 14 nm. The cache of Intel Atom D2550 is at 1.00 MB. The processor is manufactured in 32 nm.
