WCCFTech reports (LINK) that in a survey report of machines running PassMark (Australian CPU benchmarking company), the company reported AMD's market share increasing to 40% for the first time in a very long time. Lats time Intel and AMD were close were in 2005 when AMD was still operating its Fab in Dresden, Germany.
AMD has since then moved to fabricate its processors first at Globalfoundires and then moved over to TSMC. The current Zen 2 based processors are made using TSMC 7 nm while Intel runs its own 14 and 10 nm technology. Intel 10 nm and TSMC 7 nm are roughly comparable when it comes to scaling dimensions.
This graph counts the baselines submitted to PassMark during the period and therefore is representative of CPUs in use rather than CPUs purchased (PassMark).
