In a highly unusual move, Intel is allegedly rolling back the production of some of their chipsets to 22nm. Earlier this year, Intel suspended H310 chipset production due to 14nm production troubles, while other sites reported that Intel was outsourcing some chipsets to TSMC's 14nm node. But mydrivers.com claims that Intel is manufacturing the "H310C" chipset on their own 22nm node. Photos of the H310C chipset suggest it is significantly larger than the H310, and the website claims it will feature support for Windows 7, which likely an effort to appeal to the Chinese market.
The new respin is expected to replace the older chip on the newer process (confusing, I know) eventually. It's not clear how widespread this move is, or if Intel will take similar action with other chipsets that it builds. Intel has never stated how much of its factory floor is devoted to manufacturing specific hardware, but chipset manufacturing should be a relatively small percentage of the total compared with CPUs, particularly given the size of some of Intel’s largest CPU cores. One thing to keep in mind is that these plans would have been put in place months ago. The news might be new, but the timeline isn't - this has always been part of Intel’s plan to deal with its own 14nm capacity shortage given how long it takes to ramp a part on a different node.
