The Intel CPUs that we recommend in our System Guides may be fine for the average builder, but workstations are a different beast. Those systems have requirements that regular PCs don't, like support for ECC memory, and they usually come along with a Quadro or FirePro graphics card, making integrated graphics redundant. Intel is extending Skylake performance and workstation-friendly feature sets to the lower end of that market today with the Xeon E3-1200 v5 product family.
These quad-core chips all support up to 64GB of DDR3L or DDR4 ECC RAM. The major differences between the various models are clock speeds, integrated graphics, Hyper-Threading support, and TDPs. The lineup ranges from the 25W, 2GHz Xeon E3-1235L v5, to the 45W E3-1260L v5, to the 80W, 3.7GHz E3-1280 v5.
E3-1200 v5 chips with integrated graphics come with Intel's P530 IGP, which the company says is ISV-certified for compatibility with common professional graphics applications. Intel also claims that E3-1200 v5 chips provide up to 27% better performance in computing and graphics tasks than their Xeon E3-1200 v3 predecessors.
