Is SGS Thomson selling and manufacturing the Cyrix 6×86?
A. 6x86s with a ST6x86Pxxx+ label on the front of them are 6x86s that are being manufactured and sold by SGS Thomson. SGS Thomson is a giant global independent semiconductor supplier that designs, develops, and manufactures semiconductors. SGS Thomson has a manufacturing agreement with Cyrix very similar to IBM’s. The great thing about this is there is another set of serial and revision numbers to keep up with and we all can be confused about them even more than we already are. However, the ibmm1.exe utility should still report the proper revision number. My recommendation: buy and be content with an Cyrix/IBM 6×86. Stay away from SGS-Thomson. According to Directlink.cgi-EBN19970331S0007 (www.techweb.com) their manufacturing process was so poor that Cyrix themselves didn’t even buy the 6x86s that came off their fab lines.
