The Bloomberg article words this very differently:
> The chipmaker had 113,700 employees as of July.
> Some divisions, including Intel’s sales and marketing group, could see cuts affecting about 20% of staff, according to the people.
To infer 20,000 total employees from that is making some assumptions, and also misrepresents the article it cites.
(Not to take away from the overall message that this will be a big cut.)
