- #Intel vs AMD
- CPUs lacked brand names until the 1990s, identified by part numbers and clock speeds.
- Intel introduced the Pentium in 1993 as the successor to the 486, marking the start of branded CPUs.
- The Pentium was significantly faster than the 486, with initial speeds of 60 and 66 MHz.
- Intel faced competition from AMD and Cyrix, who also produced 486 and Pentium-class CPUs.
- AMD and Cyrix developed their own Pentium successors, like the AMD K5 and Cyrix 6x86, but struggled to match Intel's performance.
- Legal battles over CPU cloning and naming schemes led to market confusion and the need for trademarkable names like Pentium.
- IBM and other manufacturers produced 486 clones under licensing agreements, affecting Intel's market dominance.
- NexGen, IDT, and Rise attempted to compete with Intel but faced challenges in performance and market acceptance.
- AMD emerged as Intel's primary competitor, especially with the Athlon and later Ryzen series.
- Modern CPU branding by Intel (Core i-series) and AMD (Ryzen series) simplifies performance class identification but retains complexity in comparing generations.
