Nowhere in the linked article is there any mention of 40th anniversary. The title is simply "Intel’s 28-Core 5 GHz CPU: Coming in Q4" and the first line of the article is "...the launch of Intel’s first 5 GHz processor, the 6-core Core i7-8086K, Intel today also showcased a 28-core single socket machine also running at 5 GHz." A bit of Googling verifies that you are at least partially correct: "Intel announced that it is releasing the Core i7-8086K, a special edition processor that commemorates the 40th anniversary of the 8086..." and "...reports speculated that Intel would only produce 50,000 units. Our sources have confirmed that this is a limited-edition chip, so Intel isn't positioning it against AMD's competing Ryzen processors."
