Right - Intel had bad manufacturing problems at the time.

After the broken 486SXes started making money for Intel, they figured out how to make better 486DXes, and also a few 486es without the FPU. So they kept SX supplies up for a while longer, at lower cost and higher profit, until the Pentium replaced all 486es.
