Summary

The Intel Xeon E3-1515M v5 is a processor that once formed a solid foundation for mobile workstations. It utilizes the Skylake S architecture and was manufactured using the advanced 14nm process. Particularly noteworthy is the integrated graphics solution, the Intel Iris Pro Graphics P580. This offered considerable graphic performance for an integrated unit at the time.

This was a major plus for many professional users who did not want a separate graphics card. With its 8 MB Level 3 Cache, the processor also delivered good overall performance even in more demanding tasks. It was developed for users who were dependent on reliable and stable computing power even on the go.

We were surprised at how well it can still hold up in some specialized applications. It remains an option where the stability of the Xeon segment counts. This processor remains an interesting choice for those who were looking for an integrated graphics solution with higher performance.
