Benchmarks & Specs

Last updated:
The Intel Atom C3958, based on the Denverton architecture, remains a notable option. This processor was manufactured in the 14 nm process size. It showed its strengths particularly in environments that emphasized efficiency. With 16 cores, it offered considerable computing power for its class.

This made it well-suited for versatile network applications and microservers. Another positive detail is the generous 16 MB Level-2 cache. It ensured rapid data processing and contributed significantly to overall stability. Its connectivity was also well-thought-out. With PCIe 3.0, it enabled flexible expansions, which was important for its area of application.

The maximum memory bandwidth of 38 GB/s reliably supported data-intensive tasks. We still often see the Intel Atom C3958 in specialized appliance systems today. It continues to provide a solid and reliable foundation there. Its design for stable performance with moderate energy consumption still makes it interesting.
  • 16 cores for diverse tasks
  • Generous 16 MB Level-2 cache
  • Solid connectivity with PCIe 3.0
  • Reliable and energy-efficient
