Benchmarks & Specs

Last updated:
The Intel Core i5-8400H was developed as a processor for mobile devices. It comes from the Coffee Lake H architecture and was manufactured using the 14 nm process. Although the model is a few years old, it still offers solid performance. For everyday tasks, it is always a good choice.

We see that it is ideal for office applications or browsing the web. Watching media content is also easily possible with it. A major advantage of this chip is its integrated graphics unit. The Intel HD Graphics 630 enables smooth image reproduction. You can easily watch videos with it. A separate graphics card is not necessary for this.

For its time, the 8 MB Level 3 Cache was quite remarkable. This significantly supported the overall performance of the system. With a maximum memory bandwidth of 43 GB/s, the processor processes data streams quickly. This CPU could be found in many laptops of its generation. There, it reliably contributed to system performance.

Even today, it is still possible to work well with devices that use this processor. We think it proves the durability of Intel's mobile processors.
