Intel Xeon E3-1265L v3
Benchmarks & Specs

Last updated:
The Intel Xeon E3-1265L v3 is a special processor based on the Haswell S architecture. It was manufactured using the proven 22 nm manufacturing process. This chip was originally designed for energy-efficient workstations or compact server environments. One of its outstanding features is its remarkably low power consumption.

The L in the name clearly indicates this feature. This makes it an interesting option for systems where efficiency is paramount. In addition, the processor has an integrated Intel HD Graphics (Haswell GT1) graphics unit. This allows systems to operate without an additional, dedicated graphics card.

This saves both space and potential costs. With 8 MB Level 3 Cache, it offers a solid foundation for data processing. We appreciate the reliability that you can expect from a Xeon processor. It uses PCIe 3.0 for connecting expansion cards. Its maximum memory bandwidth is 26 GB/s. Even though this processor is no longer the newest, it still performs its tasks stably and reliably.

It remains a proven choice for specific applications where stability and moderate power consumption are required.
  • Low power consumption
  • Integrated Intel HD Graphics (Haswell GT1)
  • High Xeon reliability
  • Solid 8 MB Level 3 Cache
