Actually it turns out that Intel was right...

The article was wrong.

In total, each processor offers 128 I/O channels. In two socket configurations, 64 channels from each processor are used for Infinity Fabric connectivity, leaving an aggregate of 128 I/O channels still available. As such, both one socket and two socket configurations offer nearly identical I/O options. The main thing the I/O channels can be used for is PCIe connectivity, with up to eight PCIe 3.0x16 connections per system.
