Benchmarks & Specs

Last updated:
The Intel Xeon E5-2643 v3 is a remarkable processor. It was originally designed for demanding server and workstation environments. This chip is based on the proven Haswell E architecture. It was manufactured using the robust 22 nm process, which speaks for its solid and durable construction.

A particularly positive feature is the generous 20 MB L3 cache. This allows fast access to frequently needed data, noticeably supporting overall performance. Additionally, the processor offers a maximum memory bandwidth of 68 GB/s. This ensures efficient data exchange for demanding tasks. The Intel Xeon E5-2643 v3 also features PCIe 3.0 connectivity.

This is important for the use of various expansion cards. Even after some time, this processor still delivers reliable performance. It is still well suited for specific, computationally intensive applications. We can confirm how robust this type of processor was built. The Intel Xeon E5-2643 v3 remains a solid and quite capable choice.

It is not a sprinter, but rather a reliable endurance runner.
