The change is reflected in the latest microcode revision guidance (PDF) from Intel, which now lists a new "stopped" status next to a handful of processor families.
The chip lines affected are largely older, and include: Bloomfield and Bloomfield Xeon, Clarksfield, Gulftown, Harpertown Xeon C0 and E0, Jasper Forest, Penryn/QC, SoFIA 3GR, Wolfdale C0 and M0, Wolfdale E0 and R0, Wolfdale Xeon C0 and Xeon E0, Yorkfield, and Yorkfield Xeon.
"After a comprehensive investigation of the microarchitectures and microcode capabilities for these products, Intel has determined to not release microcode updates for these products for one or more reasons", the company noted.

On March 29, Russian Federation ordered the expulsion of 60 U.S. diplomats and the closing of the United States consulate in St. Last week, however, America joined or Western countries in imposing harsh reprisals on Russian Federation for chemical attack.
Some of the affected processors are more than a decade old, dating back to 2007, and the majority were sold between then and 2011-Intel's SoFIA Atom processor is a lone exception. The document offers information on the status of microcode updates to help users and OEMs track patches.
"Based on customer inputs, most of these products are implemented as "closed systems" and therefore are expected to have a lower likelihood of exposure to these vulnerabilities," explained Intel.
It is based on Coffee Lake platform, the new chips, according to Intel will deliver up to 41% more FPS (frames per second) in gameplay, allowing 59% faster performance in video editing apps, in comparison to the previous generation chips that used the same discrete graphics hardware.
If you have one of these chips, Intel seems to suggest buying a new CPU and motherboard is your best option. though they don't have to be from Intel, now do they?
