AMD gave Intel a run for its money when in the mid 1990’s AMD’s K5 processor had all features of Intel’s Pentium processor and was sure to grab a lot of Intel’s market share.

The opportunity AMD had got with its K5 chip to topple Intel’s market leader position was squandered when the K5 chips came to market later than expected due to issues in getting the chips delivered to market on time.

Adopted from Jim Collins’s book titled “Great By Choice”
