Now that Intel has launched more than 30 Xeon E5-series CPUs, we felt it necessary to revisit the product family and help you sort out the company's nomenclature. We're even taking the opportunity to list out all of the specifications in one place!
We got an early look at Intel's latest business-class processors with Intel Xeon E5-2600: Doing Damage With Two Eight-Core CPUs. However, that piece only covered one SKU (the workstation-oriented E5-2687W) in a very crowded line-up of dual-socket-capable chips.
Recently, the company expanded the dual-socket segment to include more entry-level models (the Xeon E5-2400s) and added a number of four-socket-capable processors (the Xeon E5-4600s).
The following list comes from our E5-2600 story and covers all 17 of those models.

In addition, there are now eight Xeon E5-4600 CPU models and nine Xeon E5-2400-series processors. The more detailed breakdown of those goes as follows:

I'm wondering if Intel included too many models. It's a bit crowded, and could easily confuse people looking into these products and cause analysis paralysis.
How about some clock speeds?
And no mention of DDIO and other E5 Xeon-specific features?
To darn high, for the most part.
