Benchmarks & Specs

Last updated:
The Intel Atom Z3785, a member of the Bay Trail family, was a noteworthy processor when it was introduced. We often saw it as the centerpiece of many mobile devices. Manufactured using the 22-nanometer process, it enabled high energy efficiency. This led to impressively long battery life, a great advantage on the go.

Its integrated Intel HD Graphics (Bay Trail GT1) provided reliable graphics performance for everyday tasks. This was perfectly adequate for videos and simple applications. Another advantage was its ability to power compact and affordable devices. The processor contributed significantly to making tablets and netbooks accessible to many people.

With 2 MB of L3 cache, it offered a solid foundation for its class. The maximum memory bandwidth was 21 GB/s. Even today, it is no longer one of the fastest processors. Nevertheless, the Intel Atom Z3785 fulfills its purpose. It remains useful in many basic scenarios. It remains a symbol of the development of mobile, energy-efficient computers.

It proved that even smaller CPUs can have a big impact.
  • High energy efficiency
  • Integrated graphics for everyday tasks
  • Enabled compact and affordable devices
