Already in June Intel brought its 3. Gen Xeon Scalable CPU family, also known as the Cooper Lake, but still based on the 14nm architecture. Now some people in mainland China (where else?) have gotten their hands on the first QA (Qualified Sample) of Cooper Lake chips, which have an interesting design for the family.
