Benchmarks & Specs

Last updated:
The Intel Atom E3805 is a processor specifically designed for embedded systems. It is based on the Bay Trail architecture and is manufactured using the 22 nanometer process. Its design aims for remarkable energy efficiency. This makes it an excellent choice for applications that consume little power.

It often even enables the construction of fanless devices.High reliability is a key advantage of the Intel Atom E3805. This characteristic is crucial for continuous operation, such as in industry or with thin clients. The processor also offers good integration into compact systems. Thus, it is ideal for solutions where a small footprint is important.The Intel Atom E3805 has a 1 MB L3 cache.

It also supports the PCIe 2.0 standard. The maximum memory bandwidth is 9 GB per second. Although it does not achieve top scores in benchmarks, it remains very functional for its area of application. We still see it in many specialized devices today. There, it shows that consistent performance can be more important than pure computing power.

This processor is a good example of a durable design.
  • High energy efficiency
  • Designed for high reliability
